• Answer:

  first I would drop the caps. they won't help you any. Next you will definitly need to upgrade your alternator to run those 4 amplifiers. thats way more power then a stock charging system can handle. now you can hook up each subwoofer to a hifonics amp. and then you have 12 speakers to go with 2 amps. there's a few ways you could set that up. Maybe use one of those kicker amps to power the speakers on each side of the car. (like one amp for the speakers on the right and one for those on the left). or an amp for the 6" subs and rear speakers, then the other amp for the front speakers. so 6x9's and subs on one kicker. 5x7's, 6" 2 ways, and tweeters on the other amp. however you do it, just mkae sure you don't present any of your amps with an ohm load too low for it to handle and you'll be ok.
