Any suggestions would be appreciated. I'm pushing 2 13.5 w7s with a 1200 1v3 slash and a stinger 2 farrad cap. In a 2012 buick enclave. Bought a box from sonix enclousre stage 3 for the pair of w7s tuned at like 34hz. Do I need to upgrade my electrical? And what else can I do to make these bad boys shine?
