Originally posted by IowaBoomer If your electrical system is under a serious strain, a cap is nothing more than a band-aid on a headshot. Not gonna help ****. If this is the case, a new battery/alternator combo is the only way to help it, short of redoing all of your car's wiring.
Now, if your elec. system is pretty well okie dokie while playing regular music you listen to daily, a cap can do no harm. A cap will store batt. power and send it out when the amp needs it. And yes, 3.0 fareds on a 1000 watt amp is overkill. 1.0 should be enough, but you can go 1.5 or even 2.0 if you are paranoid/upgrading later.
