Do I have enough electrical?

[Spldecendant 10+ year member]

I have a 07 Tahoe with 2 xsd3400 upfront with a big 3 going to each with 4/0 connecting the 2. Then I have a mechman 270a alt all knuconceptz wire 2 runs of 0 gauge to the rear with 2 300 amp fuses then a d3100 in the rear this is power a lanzar opti7001d it's rated at 5100rms at 1 ohm and I have it wired to 1ohm then I have a 400rms highs amp just ran of the d3100 of the back battery. Will there be sinificant voltage drop or should I be able to stay about 12.5v?

considering you won't be close to 5100watts with imp rise, I'd be beyond pissed if it dropped to 12.5v....

Yea it probley rise into the 2ohm range which is like 3000rms So I should have almost no rise maybe with solid voltage I'm gonna wire to .25 lol 2 more d3100's
