Ok so yesterday my car went crazy on me, i turned it off, took the key out, and the car would still run, only until my toggle switch for my amplifier was turned to off. however when the car was on with the keys in it and i turned the switch off, the bass still remained. i got a new switch, that didnt work, unplugged everything from my amp and plugged it back in, everything went back to normal. now my problem is, without changing any setting on the amplifier, bass level ranges over time and clips at less then half according to the bass knob. before i had it so i could crank it up all the way and bass would remain constant and not clip. can someone help me in diagnosing this problem?????
