4 gauge enough?

[NJTStang11 10+ year member]

System setup is

2 12" Pioneer Premier W3004SPL's (1000rms each)

Power Acoustik a2400db Amp

Set to 1ohm

I want to hook everything up and then do the big 3 with excess wiring. I have a 4 gauge kit lying around my house but on the front it says only 1100 watts. Should I just sell this one and buy myself a 2 or 0 gauge wiring kit? Would 4 gauge on big 3 be a waste anyways?

Also, a friend wants to know if his bmw 328i w/ 2 cvr's and a crunch 1000watt monoblock will be ok without the big 3?

I would run 0 gauge just in case and for headroom incase you want to upgrade later...Big 3, well, go big or go home. Do it in 0...

you can do it, wont be hitting every dB you could but if numbers dont matter it will run on 4ga fine. I did it with 2200 watts daily.
