I just purchased 3 JL Audio 10W6V2, and a Zapco Reference 750. Currently i am running 2 JL Audio 10W0 being powered by JL 250 Wt. and MB Quart components up front pioneer 6X9 rear all powered by JL e4300. If i put the W6's in do i need a power cap? Would i need to add another battery ( Currently 3 month old Optima)? Do i need HO alternator? ( i have pulley kit on my car, should i remove?) i guess i also need a distrobution block. Amp requires a lot of current.

 

Most people would recommend a cap but I don't believe in them unless its 30 farads and above. Your battery is fine but if you are really concerned, spend your money on an Ohio generator HO alt. Its money well spent trust me.
