How bigs your alt? You may be fine with just the big three upgrade. But if you do see decent voltage drop then go for a second or better battery

big 3 in 1/0

upgraded battery under the hood

1/0 from battery to amp

that should suffice depending on your stock alt amperage.

if you still have voltage drop get a HO alt

140- 150 amp

you'll be fine with your stock alt, like was previously stated, upgrade the Big 3, and use 1/0 from your battery to your amp, also make sure you fuse that run for your safety. Looking into a new agm type underhood battery wouldnt hurt either.
