Question: Dose it have a on and off switch
Document: No on/off switch so I pulled out the power when not in use.Nice little unit, pretty sick, wish i had a ATV to put it on.
I havent tried it on the trail yet but it sounds great and simple to install. The only negatives is that it doesnt have an on/off switch or a volume control.
Loud, clear, and easy to install...mounted on the front of my sportsman 800 in about 20 minutes...be careful though if you hardwire directly to battery you need to put a switch on the radio to keep it from draining your battery
As far as sound, it is amazing for the price and it has plenty of power to overcome the diesel engine at half volume. It could not have worked out better. This thing is made like a tank and sounds awesome. I would highly recommend it. The only negative I have is that it does not have a built-in power switch so it will drain your battery if you do not unplug it or wire in your own switch. Not a huge deal though.
This is a MUST HAVE for any ATV/music enthusiast. It was easy to hook up and when I got it linked to my GS4 via bluetooth, I was amazed by the sound quality.One thing that totally sucks about the unit is that it is ALWAYS drawing power from the ATV's battery. Even when the unit is off, there's a small LED light that draws power. I ended up getting an in-line switch so that I could physically turn this thing off when it's not being used.
It came with the 12 V battery connector which I just saved for something else because the chord stretched just perfect to my battery by itself. I put a led rocker switch on the rack to avoid  a constant supply which in turn would kill the battery. This took extra time because the rack had to come off to drill out the counter-sunk hole underneath the rack. I added a couple extra huge zip ties to secure it where it won't move at all.
I recently purchased a Kubota BX25D tractor and I wanted to put some tunes on it. Stereo's made specifically for tractors run $300 to $400 because they have to withstand the dirt, moisture, etc. I saw this bad boy in a few ATV videos and the light bulb appeared. My Kubota has ROPS so I was able to mount this to the top of the rollover bar with the included straps. I hot wired it directly to the battery with a switch and fuse in between.
I purchased this to use on my motorcycle. I mounted it to the luggage rack on the back of my suzuki boulevarde M109. I added an on/off switch, so I wouldnt get the static when not being used. Its very durable. I expected better sound quality coming from 6 inch speakers. Very little low end. I had to change my ipod eq to flat to cut out the bass and prevent distortion. At high volume, the sound really distorts.
worst buy ever , I hope they do everything fast , I bought because i was going to give it to my brother for his birthday , pay extra for shipping for no reason
works great but after having it on my ATV for about 3 weeks i noticed the paint and protective liner was rubbing off where it sat on the rack. overall the sound quality is good. it can be spotty on some songs if the volume is turned up loud but other than that it is a good quality sound for the price. very easy to install. 5 min and you are ready to go.
Answer: No it's powered by the 12V outlet, most wire the 12V outlet to the key switch. but you control the volume via MP3 player
