Thanks Ron, I am pretty sure everything is set right on the HU, and I even switched them around to see if there was any noticeable difference. I tried disconnecting the bass remote knob thinking that thing could be messed up and still same result
RCAs are labeled since I used the remote line that is integrated with the RCAs... I labeled one set "R" for "rear" and "remote"... Simple and idiot proof to avoid problems hahaha. Friday night I took apart the dash and pulled the HU again and re-soldered and verified all connections. I might have to take Big up on the offer just to get another set of good eyes on it. I'm a DIYer and can usually get the job done but this has me stumped.
Like I said, I've done installs before when I was a young punk and they sounded better than this and were definitely done a hell of a lot messier, i.e. twist the ole wires and wrap em in electrical tape! Never had components and just supplied as much power as I could to everything!
