    4 runs?

    Planning on hopefully getting a Memphis 4k. I heard it wasn't as power hungry as some amps in its class. So I was wondering for wire if I could do 4 runs of ofc 4 gauge from knu? Or should I do 2 runs of 1/0 ofc? It's like the same price but didn't know if I'd get a tiny bit more with the 4 runs.....? Getting batts and alt too so just the wire is the main question right now.



    Current setup
    OZ audio power 12.1s x2
    DD M3
    Alpine cde 9852
    4.2 cubes @ 36hz:

    really? Will a 275 amp alt be able to keep up as long as I don't go max vol for long periods of time? Like no more than like 20 mins at a time then let it charge for like 5 mins? Gunna hopefully have like 3 deka g31 batts or whatever they are. Haha

    You need 2 power and 2 ground runs. One run of 1/0 is only good for 300 amps for that lenght

    Ya was thinking I'd ground in the back till I get more wire then do 1 run to the front and have the 2 grounds in the back. Gunna have a buss bar on batts in the spare tire well and just connect both grounds to either side..... Would that work ya think?
