Electrical for Q1-4500 and Q4-90

[cjm86]

I'm starting a new build with tax returns and was wondering what kind of electrical upgrades I'll be needing. Q1-4500 and a Q4-90. Subs will be (2) HDC4 12s (if I can fit a 5cu ft box in my Cavalier and have room for the batteries) or (2) HDC3 10s.

Was thinking HO alt obviously, I think 270amp is the biggest I've seen for my car. 2 runs of power and ground, big 3 obviously and 3 batteries in the back.

Will that be enough?

What size wire are you using?

[cjm86]

1/0. Probably Sky High

Sky high 0/1 ofc will work.
