Im looking to use a Hifonics Brutus 1700.D to power my 2 JL 12W6V2s. I have a stock battery and am going to run it at 4 Ohms, which is 600 RMS. The specs say I need to use a 160 amp ANL fuse and 2 gauge wiring. I currently have 4 gauge power and ground in my car, so I dont want to redo all of the wiring. Would this be okay since I will not be using all of the power that amp can supply. Also I wanted to see if using a 150 amp ANL fuse in my fusebox by the battery will be okay? Just dont want to risk blowing the amp.

Thanks
