Speaker Problems (strange) Polk 691dB
Folks;
Car: 2007 Cobalt LT, 2 door Coupe, Competition Yellow, with original head unit (not the Pioneer version). Manual door locks and windows, etc. Nothing fancy.
Backgound: I had the original stock speakers replaced with Polk 6x9's in the back and 6.5's in the front. The installation was done by a now-defunct retailer so, I can't go back to them for help or assistance on the problem.
Problem: Every so often my speakers will go dead for a few seconds
and then come back to life with a totally different sound (base, loudness, treble all change). I don't experience any other electrical problems, the lights don't dim...everything else fucntions as it should.
Questions:
A). What could be the cause of this weird problem????
B). What can I do to solve the issue???
C). and, a side question: Does anyone know the specifications for the factory Head Unit on 2007 Cobalts (I have looked everywhere and I can't seem to find any information....).
Thanks for any aid and assistance/advice you can provide!!!!

Loose connection in either headunit side or speaker side.
Fix loose connection at point of looseness.
I don't think it's much published. Anyone who's interested gets an aftermarket radio.
