I have 2 eclipse 88120 DVC subs in a sealed box powered by a JBL BP1200 running at 1 ohm (i think...i have the pos of both coils on both subs going to the pos amp out on one side [left channel] and the negs of both coils on both subs going to the neg amp out on the other side [right channel]...these subs are 4 ohm DVC so that should be 1 ohm impedance right?) I have a dodge neon so i knew that i would need a bigger alt so i bought a 135 amp alternator. Well even during the day with no headlights on or anything the HU still dims when the bass hits and i don't have the gain on the amp set above half. The bass boost is only at about 1 and the low pass is set to about 40. So i'm wondering what do i need now? I was thinking about a 2 farad cap but i've heard ppl say that they don't really help and are just a bigger burden on the alt. And i've heard that a deep cycle battery is an option but then don't you need to hook the alt to it in order to keep charged? Thanks for your help
