Only two speakers work when a CD is being played...either MP3 or regular CD's. Why are the other speakers and subwoofer not playing sounds. Model DV7500

I'm not an expert but often people connect subs to normal speaker wires in back of the radio. You need a dedicated subwoofer line so high frequency sound doesn't go to the subs. Only bass. Sounds like it wasn't wired properly.

It's either a bad audio chip or if you are playing mp3's (or some other form of compressed audio) the mp3's may be of poor quality. Especially if you downloaded them from a free mp3 site. Try playing a regular CD in the drive and see how that sounds. If you are using a CD in the first place then try cleaning the CD/DVD drive.

i know this may sound dumb but did you check the cd for scratches or fingerprints?
is this a cd that you burned from the computer? if so is it the correct type and in the correct format..
Sometimes when burning cd's on the computer depending on what software you are using if the bitrate is set to high (above 128Kbps) then the cd will not play on normal cd player
Also when burning cds on the computer the session must be closed completely before it can be played on a regular cd player

Try a brand new store bought type cd and see if it works if it still does not play then it is possible that the laser has somehow become "out of alignment" and that is too difficult to fix and better to be replaced

But by your description it sounds more like the cd is dirty or scratched

It is also possible that the stereo is wore out or malfunctioning

hope this info helps

If the cd is an mp3 cd it will only work in a aftermarket or mp3 compatible cd player.
cd-r's aren't always compatible to begin with in older model cars. Best bet would be to by an aftermarket cd player and you can play whatever cd type you want.

it sounds like you are using the blue wire (antenna remote turn on) instead of the blue/white (amplifier remote turn on) wire to turn your amplifier on.

cd decks that can play mp3 format cds should be able to play regular cds. there is not mp3 mode per se.

after you play a cd while the cd is playing go into your audio settings and adjust theres settings foe each part on a stereo if u set the audio for AM//FM then play a cd the stereo changes to the cd settings

try recording a cd as a wma instead of mp3 format. i had this problem before and that worked for me

My issue was that I didn't have the blue "amp" wire hooked up and I had a factory amp.

Hi i have just looked up your stereo and that kenwood doesnt support mp3 playback.
Unlucky mate.
In order to play a cd like that the head unit must support mp3 playback
