Personally I like capacitors. I still believe in going with a quality battery (optima blue top), running 2 gauge wire from the battery (I have another battery in series with an isolator) to the 4 farad capacitor, 4 gauge to the distribution block and 8 guage to the 3 amps. If done correctly I get incredible sound and clarity out of my 14 speakers! My speakers are kickers and clarion (so not high end) but because of the clean power I get kudos from everyone aboard. The system really rocks!
