Help: Static on left channel after comp. install

[BauerJackBauer]

I just installed PVI-269 MB Quart components and a RAB-250 MB Quart amp last night. I have a kenwood KDC-MP538U deck. After I got every thing all wired and mounted, I put the negative back on and turned on the car and deck. The Green power light came on for the amp and the red indicator light stayed off. When i switched from standby to CD on the deck music came out of the right and static out of the left 6x9 and tweeter. I checked all connections and they seem to be fine. I'm using 8GA power and ground and 14GA speaker wire. I'm grounded to one of the big bolts that holds the seat down. I sanded this area, but does this not go to the car's chassis? I dont understand if that was the problem because why would the right work? Any ideas what could be wrong?

Note: my speaker wire/RCAs are away from power wires.

static in one channel could be a bad deck or amp

I dont think it is because i had 6x8s with this same amp and deck it a previous car and it worked fine, nothing was dropped or hurt in any way

I'd spray some WD40 or contact cleaner on the tuning pots and twist them...there may be some dust causing it.....

I'll try that CRX. Stanky do you think it could be a bad crossover box? The component speakers and car are the only new items in this stereo system. I dont think its the speaker because of the fact its the whole left channel. When i get a chance I guess I can switch stuff to see what happens

try a different ground, an actual good ground not just a bolt you can easily use. it'll work with a bad ground put you'll have issues much like you have.

Yeah thats the first thing i will try. I just really dont understand how that would only effect (or affect, i dk) one channel. it would make more sense if it was both

Tried a completely new ground directly on the chassis and it did not help

did you put a DMM to it to make sure it was a good grounding point?

swap the speaker outputs at the amp and see if the sound follows. if it follows change the RCA outputs. if it follows the RCAs it's your head unit. if it follows just the amp. it's the amp.

I had a MB Quart/Kenwood Rep look at it and we did some test and long story short the channel is bad. He's hooking me up with a 4 channel amp that i will bridge and it will kill.
