I have a question about wiring with my system. I plan on running 4awg from the battery to my distribution block which is (1) 4awg in and (2)8awg out. I have a 500w 4-channel amp and a 650w mono channel amp. I’ll also be running a 150amp ANL fuse.
Will this be sufficient?
depends on the amp … how long of a wire run … fuse rating of the amps …
you should have no problem … make sure to keep your grounds as short as possible
150 amp is a touch on the high side for 4 ga I back it down to around a 100amp
