Re: Ampin the EB
hmmmm, capacitors are much more for show than anything. If you have trouble with power drain, id consider getting a new battery. (eg, a Gel Cell battery) these multiply power much faster and can hold a greater capacity. Unless you're running biggggggggg power subs and speakers, you wont need to run two batteries. In my old car (Ford Meteor) was running 2 12" subs @ 600wrms and never had any troubles.
As for an amp, if you havent already bought one. If you are wishing to run only the subs on it, i would consider buying a Monoblock amp, (designed for subs as they hold a greater charge for those *burps* eg. loud deep notes) but these amps are much more expensive than you're everyday amp. but if you're serious about your music, well worth a look.
Also, dont make the common mistake and run both subs AND speakers on the same amp. the subs will drain all the power out of the amp and leave crackly shitty, sweet f**k all power for your speakers. if anything, amp your subs, and keep your speakers running off your headunit. providing you have a decent headunit this will still sound awesome, mine did :)
hope this helps, and i apologize for the long post. if you have any queries feel free to pm me :)
