This weekend, I finaly hooked up my amp and sub. Hooked everything up right and of course I drained the battery setting the stereo. Got the battery re-charged and all was good. Well today while I was driving, my car stalled for a quick second then was fine and then all of a sudden the battery guage maxed out and the check guages light came on. So I pulled over and disconnected the amp. Battery guage went back to normal and no issues. Could it be grounded bad. I grounded it to the metal tire mount but I am thinking I should have mounted it right to the bare metal on the body. Could this be what is causing my battery issue?

 

The amp wouldn't work if it wasn't grounded though...?

 

ya ur supposed to have it grounded to a bare metal surface that is directly on the chassis.

 

I know, but usually something doesn't work at all if it's not grounded properly, so if it works I would assume it's a good ground..

 

It just doesnt make sense that the battery guage will shoot up in high RPMs and check guages light pops on. When I stop the guage drops back to 14 and the guages light turns off. When I disconnect the amp everything goes back to normal.

 

what do u have the main power line to the amp hooked to, the alternator or the battery.

when i did my system in my 92 chevy lumina, (thats right ur jealous) i hooked it up right were it is going in the relay box

 

get power and groung direct from battery
