i currently have 3-12w6 JL subs, running off of a 600 watt ppi amp. now! i have a 215 amp high output powermaster Alternator, and an Odyssey PC1200 battery. and i have a 1 farad cap. every time my bass hits, my lights dim and my guages freak out. can someone please give me suggestions??????? caps just don't work so please don't suggest another cap. ive spent too much money on useless caps.
