i got a 1996 ford contour gl. i want to put subs in it. i already put in new speakers and head unit. i was wondering if anyone has done this b/c i dont know if i will need a capacitor or not. some people tell me i will and others say i wont. others tell me to just get a high output alternator. i will only be running 600 watts at most but most likely only 300-400. has anyone done this and if so what have u done. thank you so much for your help!
