1980 cadillac eldorado 6.0l v8

I have a 1980 cadillac eldorado that is having issues with the stereo.  Everytime I give the car gas the stereo cuts out, after i let loose the gas pedal the stereo kicks back on (mainly the subwoofers cut out...the front speakers and head unit stay on).  I believe the subwoofer amp is the one that cuts out.  Also when going over 50 mph the stereo cuts out.  This usually happens when the gas pedal is pressed and engine is rev ving.  can anyone help?Nitin Nelapudi

Okay found out what it was. First off I'm using a Kenwood 1000 max power amp @ 2ohm's, 2ohm stable. (or 600 watts max @ 4ohms). The first set of subs i was running that were problematic where: 2- polk audio db 10" subs, 8ohm each. the old...old school polks in a sealed enclosure. I believe this was the problem because the speakers were 8ohms and i split to make it 4ohms the amp couldn't handle the 4ohm load??????? (or it was hooked up backwards :[ ) After installing : 2- diamond audio d3 12" subs, dvc 2ohm running parallel to the voice coils and series to the subs...running 2ohms total. (i may have it backwards but i checked it using the guide on this site, followed exactly) the problem stopped and my car is LOUD!!!!!Nitin Nelapudi
