Question: Is there connections in the rear of the unit for both a sub AND a cd changer?
Document: Overall pretty good receiver.I would have given it 4-stars.However, if you are using line-outs to power a 4channel amp, you will find that the line-outs are for rear are specifically tuned for sub-woofer use. There are options to change cut-off fretquency to as high as 200hz, but that still leaves out everything from 200hz-20khz NOT PASSED THROUGH REAR LINE OUT!WTF?
easy to install, a previous Pioneer radio -cd was in place. wiring was simple and instructions ok to use..quality of the stereo unit for adjustments was excellent.
It works well, and I love the choice of screen and button colors. The only thing that would make this unit better is a rear USB port. One feature I particularly love is the option of controlling an iPod on the unit or with the iPod. I find head unit wheels to be cumbersome when scrolling through music, so I appreciate the ability to use the mp3 player.
This head unit was good for a few months and after those few months the head unit decides to fry its own internal amp and stop sending sound to the speakers but it lets the sub woofers still hit this thing is a piece of crap
I still don't know if there is actually a way to turn the unit off.Many of these sub-menus are very esoteric and don't need to be accessed this way. The other buttons are also fairly small and easy to miss, particularly in the dark (the back lighting isn't as noticeable as it could be).
Nice Cd/USB/Ipod reads all the files. Great mixing of songs and nice bright colorful display. Enhanced the sound of my subs greatly
Well... When I got the deck and hooked it all up I found that the cd player wouldn't take in cd's. This wasn't too much of a problem since there's usb input, but now two months later that shorted out too.... This thing is definitely not worth buying just for the FM radio..
No complaints - bought it to replace a worn out factory cd player. I can't believe how cheap these have gotten. I bought one several years ago for my first car which came with a cassette only and spent $300 for one that didn't even have all the features this has.
I bought this cd player to update the cd player i had in my 1996 volkswagen jetta, I absolutely love this cd player, the sound is great, its easy to use and the color changing is awesome! Great price, great value!!!! Definitely recommend it.
In the resulting menu, turn the M.C. knob to highlight "SP-P/O Mode" and press in on the knob to select. Turn the M.C. knob to highlight "Rear/Rear" and press in on the knob to select the desired setting.This option will provide full-range and fading output from the rear amplified speaker outputs & the rear pair of pre-amp outputs.Upgraded review from two-stars to three. Why not higher?
Answer: There's a cd changer on the front of the device, had unit installed by geek squad, so i don't know about rear connections.
