yesterday i disconnected my battery to clear a cel. i reconnected it and went for a drive. whenever i accelerate hard the sound completely cuts out, except for my sub. i can hear the bass coming from my trunk no problem, but the speakers inside go out completely until i let off the gas and the car sorta evens out, as in no longer squating from the acceleration. i have the ifinity stereo (ssl package) and a sony aftermarket head unit which i hate. i checked all the wires and everything seems connected properly. i dont know what the issue is, im wondering if theres somehting wrong with the factory amp under the seat. it only does this on hard acceleration, otherwise its fine.

 

I bet the battery terminal is loose.

 

well whatever it is it stopped. i dont htink it was the battery, the voltage wouldnt drop when this was happening
