Okay... did you guys know your amps have caps in them to stabilize the power rails inside them?
So... if you have a properly built amp, the internal components will do the same as your suggested cap. So if a cap helps you, get rid of your amps.
Boxes... if you're concerned with them making noise, make them structurally sound by BRACING and RE-ENFORCING them.
Batteries only help when the voltage drops to 12.5-13 V where you shouldn't be because you're damaging your alternator at that point.
Point is, alt is what powers everything in your car when its on, so don't think all this other bull**** is going to help you when you have nothing to charge it with in the first place. If you have enough to charge that ****, then you're better off not charging it and using that energy in your amps.
