I have an 03 Cl changed the battery and alternator and main relay beforeI put in an aftermarket sound system. I have a Dual Dv271bt double din radio and a Kicker CXA 600.1 Amp 600 amps and the CompC 2 10 " speakers. The Battery I have is 600 CCA and my alternator is oem .
The Problem Im having is I was driving home yesterday and I noticed my abs and tcs light was on and my sub woofers were acting weird. By weird I mean some of the bass was hitting then you'd hear it cut out. As soon as I got home I noticed my dash lights were flickering meaning my Millage and how many miles i put in the car "trip a & b " etc. I turned the car off and tried starting it again and then it was clicking fast I let it sit for 15-20 mins and went to go start it again and It started fine but my battery light was on. Then I let the car sit for a whole hour and Started it again my battery light was gone. The next day which is today My car ran fine I drove to work fine also driving to school in a couple hours too . What could be my problem(s)?

 

Sounds like bad grounding for your amp. Where is it grounded?
