Wiring Question

Recommended Posts

Whats going on SSA. Need some advice on this wiring/electrical decision I need to make. I was running ~1000wrms on my old setup, I currently have a single run of 4 gauge Knu OFC (~20 feet) to the back where I have a distribution block. Now I upgraded amps and I will be running ~1400wrms (changed amps more because of space constraints, bigger box so less space for amps). Amplifiers have fuse ratings of 120 and 50 amps.

Now Knu claims a maximum rating of 150 amps on their 4 gauge (even though they provide a 120 amp fuse for their kit), I was wondering if I should add another run of 4 gauge to the back so I would have separate runs for each amp. Or would a run of Knu 8 gauge be enough for my mids/highs amp, it has a 50 amp fuse rating, will be running about ~400wrms off of it?

Thanks for any input!
