are batcaps bad for db drags? and do optima batteries placed in line before them hurt the amps ability to draw power? why do regular caps hurt the spl #s? i am new to this site and have never heard this before, can somebody please explain these things to me. i have two eclipse SW9152 15"s and a eclipse DA7232 two channel class d amp thats hungry for power. i have two yellow top optimas, one under the hood and one back in the trunk with two batcap and a 2farad cap. how should i use these? i have been hitting 147.4 on the termlab. can i do better #s with no cap and no batcaps?

Bottom Line on Power Supplies Fast power supplies are a myth, as all power supplies are inherently "fast" in this context. Regulated supplies are generally only used with Class-A amps to reduce ripple. These do not have to be fast, because the current variations are much lower with the Class-A topology. Most will have a fair sized electrolytic at the regulator output anyway, so they are "fast" again.
Massive capacitance and "audiophile" grade caps are not going to improve the sound of the DC from your supply, regardless of cost or claim. The power supply is a passive part of the amplifier, and has little or no influence on the sound, unless grossly and ingeniously poorly designed. I say "ingeniously", because it would take spectacular incompetence to so badly design a power supply that it audibly affected the sound at any signal level below clipping. From some of the posings I have seen on various bulletin boards, such incompetance may well be rife, since just changing a power lead makes them audibly better :-)
