I just put together a sound system for my 03 and I have a problem that I can't figure out. I hooked up the component speakers to a 4 channel amp(rears to be installed later) and everything is wired correctly from the battery to ground to remote to the deck. My problem is that the speakers will only play the radio but not a disc(tried a few of them). I don't understand, can somebody please help me out? thank you!

 

I don't have an answer for you, but you might want to try to electronics forum. There seems to be lots of smart folks over there.

 

stock head unit? aftermarket?

 

alpine head unit

 

sounds like a problem with the headunit since the amp and speakers are getting signal from radio...
bring it in to where you got it, see if they'll exchange it out

 

problem fixed. had my remote wired up to the antenna power (blue wire) and not the blue/white remote wire"dummy me". good thing im finished. thanks for the somewhat help guys. no more drama from me.
