Sound Quality and Equalizer

Hey community,

got the HU now more then 2 months,

im using PowerAmp as player, this player got a really good equalizer and PreAMP function.

But im still not pleasured with sound quality. Driving an Seat Leon Fr, this car is totally OEM

with speakers and stuff. (car is pretty much based on VW Golf V)

Without that player the music would sound really awfull to me. (no bass at all and bad quality)

The impedance of stock speakers is 4 Ohm. With my stock HU everything sounds really really great!

And now im wondering what the cause might be for sound quality and strengh went that bad.

Output should be 50Wx4, right?

When i max out system loudness, sound went really bad and strange noise in speakers.

Tried viper4android and similar programs but nothing worked really.

Now im clueless and hoping for some support of you guys. Eventhough i know its a pretty much complicated and vast issue :D :D

How yall feel aboud sound quality of HU? (enough kick bass and stuff)

Some recomendet players or programms?

Need Help :confused:

greetings

Maybe your OEM HU had a built in amp? Some have the amp built right in. Not sure about yours as we don't have that model car in the US.

As far as Viper, on my system it makes a HUGE difference. Are you sure you set it up correctly? Have you used Viper on any other device before this one so you're familiar with all its "tweaks"?
[Android Head-Units] MrG3kk0:
Hey, thanks for reply,

my stock HU has no built in amp. Its 4x50W max.

I used KingRoot to get root access for Viper, and i think i use it the right way.

In my opinion there is nothing to do it the wrong way :D

You have some tips for using it right? :)

It's here!

Unfortunately for my wife, my NU3001 arrived on Valentine's Day weekend. Time to tear into this thing! I'm going to set it up on a bench to get it all set up before installing. Anything in particular to watch out for as I get started? Pro-tips for getting this done right the first time? I've read the thread and the wiki, but I'm hoping to avoid any unanticipated landmines!
[Android Head-Units] zanix:
I think you pretty much have as much info as you will need. The only gotchyas at this point are specific to the vehicle you are installing it in. In my car I had to cut some plastic in the stereo cavity because one of the wires bumped up against it.

Took the plunge too

Dear all,

Has been reading this thread for the past 2 weeks. Ordered 3rd Feb and arranged on 9th Feb. However only got it installed yesterday.

Some comments on the set.

1) Benchmark at 18000+ but became 24000+ once I upgraded the benchmark app.

2) Nice screen but not very bright under sunlight.

3) Very crispy and beautiful sound compared to my JVC set. Even my installer was impressed.

Now some questions if you can help

1) How do I output to external roof mounted monitor? The yellow RCA cables are all inputs (3 including rear cam) but no output. My installer said that some china sets can "reverse" the in to out via settings. Is that true?

2) The rear cam is horizontally inverted. Is there a setting for me to inverse the screen?

3) Read that the music cuts off when reversing and didn't quite understand until I installed the unit. Is there any way to disable that?

4) How do you power up the set at home? I tried the nokia 5v 350mah cable and a android tv 5v 2000mah cable and both failed.

5) Is there a way to turn off the screen without powering off? I am asking as I want to play video for those seated behind. However, when I do the screen plays as well and where I am from, it is illegal to play a video when driving.

Thanks for reading. Might want to know that for problem 1, I bought a HDMI2AV set and managed to output to the external roof mounted monitor. However, it flickers and this can be quite distracting depending on the content played.

Thanks much and great information here!

Hi,

Which is the video out cable? From the wiki and my set all I see are three yellow cable for video in.

Thanks!

I use an USB to MINI USB cable plugged in USB power supply (xbox 360 works - laptop works - TV or dvd player doesn't work for me) + HDMI to MINI HDMI to connect it to my tv screen

Did you test "screen saver" apk? It show dark screen with clock or photos / images... but I fear that will be extended to the slave screens too!

I saw Picture in Picture demo... but as seen that there's no independent graphic card - it think slaves sceenn will obey to master HU...
[Android Head-Units] icyflame:
Thanks for the tips. I just did what you shared and it works. Just that my USB cable was probably too long and not too great a quality that the set keeps resetting (tried USB Xbox360, time capsule and XiaomiBox). As I couldn't find another USB cable, I had to search for alternative. Thankfully an old Garmin charger with mini-USB works and it is now running without resetting. Guess it needs at least 1 mah to run smoothly.

Can I suggest that someone update the wiki as it still states old nokia charger?

As for the screen saver apk I have not tried it but agree that it probably doesn't serve my purpose since the external monitor mirrors my screen. As a make-do, I am playing the videos with Mxplayer and once the video plays, I just swipe down on the left side to minimise the brightness so that I can't really see the screen during the day and not so visible from the outside at night.
[Android Head-Units] typos1:
Have you checked ? Some VW group cars have active rear speakers only.
[Android Head-Units] icyflame:
Btw, I have a question on hotspot from iPhone.

The set pairs up automatically for phone usage like calling and receiving calls and this is good. The other Bluetooth also pairs up automatically for airplay (although airpin lite is not giving me good results). However, I have to enable internet from the android setting every time I go back to the car even though bluetooth is already paired. Any way of auto-enabling the android Bluetooth settings to allow use of data from Bluetooth?

Thanks again!
[Android Head-Units] peregrines:
I have exactly the same problem! Its very annoying to have to reconnect wifi everytime, meanwhile bluetooth works perfectly fine! (also using iPhone 6 on IOS 8.3 )
[Android Head-Units] icyflame:
Yes I tried hotspot using both Bluetooth and wifi and both gives me the same result. Really hope it can just auto connect to the internet.

Btw I am on 8.1.3 too.

Can you upload the apk only?
[Android Head-Units] usafle:
Make sure you have Busybox installed. Viper4Android needs busybox installed for it to work.

When Viper is first run, make sure you allow the "Super Audio Quality" drive to be installed.

Change: Settings / UI / Expert

Download a Convoler from my GDrive folder and save it to your Downloads folder on your phone. I would go with one of the IRS files I already have unzipped on there (BBE / Tracs.irs)

Within the ViPER4Android app, click on "Impulse Response" under "Convolver". It will tell you that you have no impulse response files in the "[your internal sd card path]/ViPER4Android/Kernel" folder, but will also create the appropriate folders for you. Then, add the IRS files you want to use to newly created folder on your device's internal storage. The IRS files belong directly within the kernel folder. This means no subfolders.

Make sure Master Power is checked

Fir Equalizer: Acoustic

If you are using PowerAmp to play music, then there is a bunch of other steps to get PowerAmp to work with Viper.

Open up a audio file and start playing it. If you check / un-check the Master Power in Viper while audio is playing you SHOULD hear a delay in the music playing. This means you have it working correctly. Or, you can have music open and select "Driver status" from the menu and it should say "Audio Processing: Yes"

If I didn't have to go to work, I'd make this a lot more pretty with screenshots and etc..... but I've got to walk out the door.

I updated to Renedis 1.1.4 without soft keys but I still get soft keys... or am I blind?

More important: I hooked up the Android box to my tv this weekend, but ever since I put it back in the car I get zero gps signal. Maps just shows the general area (based on wifi settings) and GPS Status shows a lock on 0 satellites. Does anyone have a clue? I have already installed something like Fast GPS Lock that changed the gps.conf file... but no change :(

Wrong thread.. .

The setting is commented out. Edit the build.props
[Android Head-Units] zanix:
It seems that all of these are inputs only and there is no setting to switch them (that might be a good question/request for Summer!). There is a mini-HDMI port on the Android box that you may be able to use but the sound will re-direct through HDMI and no longer go through the head unit if you use it.

In the Update Settings app, uncheck "Whether astern mute"

You could try the screen standby app https://play.google.com/store/apps/details?id=com.nkahoang.screenstandby

I haven't tried it myself though.

I also wanted to try secondscreen https://play.google.com/store/apps/details?id=com.farmerbb.secondscreen.free to see if I could blank one screen and keep it going over HDMI, but since I do not use HDMI I haven't tried it out.

Use an automation app like tasker ot Llamma

Tips about background image

If you want change default background image (current orange with blue corner) you must to do next steps:

1. Prepare your image - light jpg (80% quality will be enouth), 1024x600 dimension

2. Create new directory rkfactory into /system/media. Full path will be /system/media/rkfactory

3. Copy your prepared (in 2) image into directory /system/media/rkfactory with name default_wallpaper.jpg

4. Reboot system

Good luck

Same here ... I used the one without buttons, but I got them :eek:
[Android Head-Units] MrG3kk0:
Thanks for that really nice reply, hepls me a lot!

BUT:

- i set up viper like you said

- my problem now is viper audio driver does not process at all :(

- i just use kingRoot and i think that kind of root doesnt work anyhow or maybe it wipes after every reboot saisson or so.

any solution for that problem bro? :D

Just Flashed V1.1.4 and MCU V34 tonight.

is there a rooted version available?

[Android Head-Units] icyflame:
I am using the mini-HDMI with the HDMI2AV device. Am glad to inform you that the sound is still directed to the head unit using this method.

Will try the to unmute when reversing tomorrow. Have also downloaded secondscreen and will try out tomorrow. Thanks for the info. Will update once I tried it out.

Tasker looks very complicated to me and Llamma only allows me to open settings if they don't detect the pairing with iPhone, but still save me some steps. Will try to look more at tasker after my exams tomorrow morning.

You have been very helpful. Thanks!

[Android Head-Units] usafle:
No, unfortunately the only pre-rooted ROM goes all the way back to version 1.x. Reddotnet made that but he is MIA due to personal issues.

Every time you upgrade your ROM, you need to re-root the device and then grant SuperSU rights to everything all over again.

There are two different root programs that people are using and they both sound similar. I, myself get confused as to which one is which. One is king root and the other is kingo root ?

OFF TOPIC: For those of you that are unaware; Xposed framework for Lollipop was released today along with a working Viper4Android lollipop version!

You're welcome ;)
[Android Head-Units] MrG3kk0:
i already re- rooted everything clean, but still doesn´t work :(

So i guess kingo root is chinese app and kingRoot is english app, thats the main difference in my opinion.

U think rooting with kingRoot is permanent and does not wipe every time i reboot?

how did you root your HU?

[Android Head-Units] usafle:
I used the English one. I can't speak for the Chinese root app. I think deeznuts has used the Chinese one. Maybe he can chime in?

Use Kingo Root. Sometimes it does not work. Just reroot it again. The second time always works.

I wish Newsmy would increase the internal memory size. It way too small. I have just a few apps installed. Out of space..... I wish there was an app that could increase the partition size without wiping data.
[Android Head-Units] deeznutz1977:
You need to root every update. Root won't persist
[Android Head-Units] zanix:
No, the audio is NOT directed to the head unit when HDMI is being used, only HDMI will have sound.

Tasker can be complicated, but there are good tutorials here on XDA http://xdaforums.com/showthread.php?t=1110775

Dang, measurements are not on the wiki. If someone does measure can they please add them?

Agreed, the internal memory really needs to be 2GB instead of 1GB. Someone here knows how to modify the update.img to do this. Tutorial please?
[Android Head-Units] icyflame:
Hmm, I have mine connected to the head unit with HDMI out to external monitor and sound still comes out from the head unit as my external monitor is not connected to the speaker. Having said that, my HDMI out is through a HDMI to RCA converter and I only connected the video av cable and not the red and white audio cables. Maybe that is why.

Thanks for the tasker link, will look at it once I am free.

As for internal memory and app installation, I am wondering too but have not found time to try it out. Out of the box, I realised that not many apps can be moved to SD. Does apps like Apps2SD work? If so, apps can be installed and moved to external SD like rooted android phones. If no one has tried it yet, I will give it a try tomorrow but that might involve full root?

Tips. How to increase /data partition

To increase /data partition upto 2GB you need make changes into parameter file into firmware.

1. Unpack firmware (using RK31xx tool or FFT)

2. Change parameter file (see attach)

2.1.

You need rename attached file into

parameter and replace old parameter file (with 1Gb /data)

3. Pack firmware again

4. Burn firmware ONLY with RKBatchTool (Upgrade or Restore mode. I think its equals), if your previous /data partition had 1Gb size

PS. I give txt extention only for download posibility!!!

ordered one for my SKoda

Been registered with this forum since few years back, but here comes my first post:

Always wanted to upgrade my Skoda stream to something better, got stream mp3, but burning CDs is pain in the neck .

Want proper android system in my car with ability to use waze not only from the phone but from the HU itself.

I got 10 vodafone pay as you go sim cards with 2 months x2 gigabytes of data on each, so got free internet for almost two years! Just need to plug in one of my spare USB modems hoping they work and keep swapping cards when the data runs out.

So ordered from Spanish website, went for EX-NU5261SKD due to my car being Skoda Octavia MK2 2005 with CAN-bus.

They seem to be on sale at the moment and selling it at €380 + €29 for the delivery to UK. Which is quite reasonable especially these days when pound as at 7 year record high against €uro (shame that most of my savings are in €uro),

Applied ECA2015FB voucher code on checkout to get €5 discount.

Paid with my credit card (so section 75 applies if anything goes wrong), but via PayPal and in euros - rejected PayPal currency exchange which is 5 cents less than the official MasterCard as I get official MasterCard rate and no fees/charges for foreign exchange, so saved almost 15 €uros.

Works out almost the same amount as ordering from China, but I'm sure delivery from Spain to Scotland should be much quicker and no risk of being stung by import taxes. So after all it should be even cheaper and quicker. Also since Chinese are currently having their New Year my chances of getting it sooner are much higher. I assume those guys in Spain got local stock?

Next thing is to get unit delivered and find the right facia for my Octavia. Anyone got one fitted to theirs?

Thanks for all those participating in this discussion and, that's mostly the main reason why I picked this unit instead of others - support from community. Well, also 2 gigabytes of RAM and quadcore CPU means a lot too :) Can't wait to get it delivered.

My Mrs will kill me....

Have one in my Skoda Superb 2012. Remember to check if you antenna connector is of the dual fakra type, then you need an adaptor to use FM/am. Was not included with my unit. Looks like it will fit right in your dashboard. Mine was a tight squeeze (lots of cables)so I did not connect the avin cables. You will also have to set your Swc manually. Canbus works great out of the box with the ac and open doors etc. Good luck, and post your findings!

[Android Head-Units] walio:
Don't care that much about radio, I could live without it actually. But I know mine is single, I found out that when tried fitting Bolero that eBay seller sent as good but wasn't so good after all. I also found that my facia wouldn't fit it, would have to get new one, so gave up, returned to seller, got my funds back, bought stream mp3, bought aux-in cable for it later, but too much interference with it, buzzing noise sometimes and picking up noises when accelerating and so on, too much hassle as well as hooking up phone to it, then changing songs on the phone... Not so practical.

Tired of those crappy Bieber songs and hundreds of boring ads on those few radio stations available in Scotland, thought would treat myself with something that can have multiple uses, and this hopefully will suit my needs.

My Skoda Octavia isn't that fancy, doesn't have SWC on the steering, but I am OK without them as long as the unit itself works fine. Also no A/C messages and doors open etc... No maxidot, just minidot (?) I guess...

Will post my findings when I get it, might even take pictures. Thanks! :)

Mine was came with 1.08 ready and the basic bluetooth works fine although you can't use the phonebook there is no any option to use it,but with an extra program you can make it available,anyway you mean to download 1.08 version from baidu site and to reflash it?and now do you have options from the second bluetooth or not?I don't know how do they mean really to work the second bluetooth and to connect with the obd,since there are not any settings about that and the manual is not efficient.

Root problems

Ok, I know we're all running under the impression that this is factory rooted. The su binary is definitely in /system/xbin. What I've observed is that this is only enabling a root ADB shell. Trying to install and use either superuser or SuperSU is failing. SuperSU complains about an old version of su then fails trying to update it and exits. Superuser doesnt work either.

Ive tried playstore installs and pushing via adb shell. Even tried extracting update.img and installing manually in system.img then rebuilding. Also tried manually installing updated su binary in various ways.

Was able to flash the modified rom but still no joy on superuser/SuperSu. In fact if I updated the su binary manually, SuperSU says there is no such binary anymore. Adb root shell still continues to function.

All the one click scripts and root tools ive tried have failed too.

I'm just an educated amateur here. Anyone else got any ideas?
