[QUOTE="ashren315, post: 8536248, member: 670616"] I have an old school 800a4 fosgate amp that I had in my old truck. I stopped using it and just disconnected it because after awhile of playing music through it, it would get really hot to touch (much hotter than any of the 3 800a2s or the 600a4 I also had in the truck) and start playing this loud screech sound through the speakers it was hooked up to. I still have this amp and have something new I would like to use this amp on now. Could an improper or undersized ground or power wire have caused it to do that? I had zero gauge running from a bank of 3 batteries that were installed in the bed of the truck with the amp (it had a hard top cover) running to a distribution fuse block and had 8 gauge power wire running from the distribution block in about a 3 to 4 foot run to the amp. The ground was similar. Zero gauge grounded to the frame of the truck running to a distribution block then 8 gauge in about a 3 to 4 foot run to the amp. Each distribution block (ground and power) was responsible for two amps each. So was it the wiring that was likely causing this or is it something else internal in the amp. It sounded great up to the point where the screeching sound would start. It never shut off or anything but I always turned the power off immediately when it started doing that sound. Thanks. [/QUOTE]
