I need advice on my car audio !

[bsantana]

I have a orion HCCA 2,000 Watts RMS, A separate voice box 1,200 watts rms and I have 4 interior speakers totaling about 800 watts rms. My Stock alternator does 130 amps. I was wondering if I throw a yellow top or xs power battery in the back with 0 gauge wiring and do the big 3 will I be fine ? or will I need a mechman high output alternator.

Welcome! Definitely do the big 3 and add the batt. Then check your voltages and see where you're at. Skip the yellow and go with the xs.

You'll need an extra battery with that setup
