Voltage Help

[thegreat22 1]

I have an 01 tahoe with 2 15's kicker cvr dvc 4 ohm wired down to 1 ohm. Us amps xt 4000 1500rms@1ohm and a crunch 1400 4 channel and a 4 farad performance teknique power cap. red top under hood and db electrical ho alt. Have not did the big three yet. At idle my voltage drops to 13 or even 12 when bass really hits. Will the big three help with 0 gauge wire. Should I buy a powermaster D680 or D975 and get rid of the cap

A cap is like putting a bandaid on a severed femoral artery

I say first do the big three and drop the cap. 12v aint all that low.
