[QUOTE="helotaxi, post: 427903, member: 550915"] Where exactly on the sheetmetal do you have it grounded? If you can get it very close to one of the bolt that attaches the cab to the frame of the truck, you might have better luck. You still want to make sure that you have a bare metal connection and that your power and ground wires are not excessively long. With only 8 ga (and that should be plenty for that amp) you won't see any benefit in running the ground back to the wire. If you were using bigger wire or had a unibody car with the amps mounted in the trunk instead of a truck then it migh make a small difference, but not with your setup. Make sure that you have good connections all along your power supply path. Try a new fuse. The one you have may not have as good an internal connection as it should. Any bad connections will cause a rise in resistance and a significant voltage drop during high current demands. The drop in voltage will cause many amps to shut off. Good luck. [/QUOTE]
