[QUOTE="LongThrow, post: 8423248, member: 661351"] I've done much research on this (as far as google goes) and I have never so many mixed reviews on the necessity of this in my life. I'll start with my problem. all my equipment is in my sig, but for the lazy scrollers, 94 ford explorer - normal battery from autozone - brand new 95 amp (same rating as the stock alternator) alternator which is specfically for this vehicle. 4 guage KnuConceptz wiring. 500w sub amp wired to 2 ohm. Tested battery at autozone, it's fine. Alternator is fine. Wiring and connections are secure. Fuses are fused properly. Ground is clear of paint and is perfect. Tested battery again with DMM, showing 12.89 at idle with car off. Car running at idle shows 14.34. However, every now and then, when my car is at a stop light, I'll have 2-4v voltage drops. I'll turn my stereo off, still having dips in the voltage. This is only when stopped, while driving is fine. was told a capacitor would fix my problem, no more than a 1.0 would be needed. is 500w + the 150w of my door speaker amp = 650w of power be too much on my stock system? Have not done big 3 uprade was told it was unnecessary for the entry-level equipment I have. I'm wearing a fireman suit so I don't get burned by the flames I'm about to encounter. [/QUOTE]
