see i had a problem were mine was dropping to 10.1v at full tilt and shutting down. i checked all wiring and connecttions. batts and alt were all reading good. but the amp read 10.1 at the terminals. so i was losing power in my fuse block, it shorted or sumthn i gess. but i removed the block and it was hot for some reason so i hooked the wire to amp(no fusing), and tested it, and has not dropped voltage of shut down since. i had my fuse 10" from the amp terminals. so now im not using any fuses. i just watch my voltage very close
