Front door speakers issues

[Brandon M 03 ram]

I have a 2003 dodge ram 2500 laramie with the infinity sound package. I have upgraded all 4 door speakers and they previously all worked great until i installed a pioneer avh-4200nex head unit myself. The balance doesnt work properly and the front door speakers hardly work since, all i hear are the tweeters from the front, any advice? I supposedly bought all of the correct harnesses and there isnt any exposed wiring, having trouble figuring out what the issue is.

if it all worked great before hand it must be the harness, unless u messed up some of the wiring from the radio to the harness, (ive dont a bunch of radio installs and it happens to the best of us) as far as the harness, they try to make them so generic that it might be wrong, ussually a different brand will work.

I absolutely agree. I've received many stereo harness adapters that had incorrect wiring and wouldn't work at all.

Have you tried to look up a wiring diagram so you can verify the correct connections were made?
