hmmm what exactly is a capacitator used for? Im about to get 2 12"s and either a 600, 800, or 1200 watt amp, will I need one of these?
They store power, help maintain continuous power to your amp. I think you should get one. Mine is Rockford Fosgate.
IMO, they steal power...but for dialy use it might help...
capacitors don't steal power
you first have to charge them before installing them, and they store electrical power like a small battery, so when you turn up the bass and the battery can't keep up, the capacitor keeps the bass pumping and therefore the lights and other electrical components will still work at their max potential.
