Celica Forums General Discussion Exterior Cap

i am a noob...wat is a cap and its use ???

from what i hav read and learded about caps it seems very important for high powered systems...i hav a high powered system (HU: Pioneer AVH-P6500, Subs:(2)JL Audio 12w7, Amps: (2) Jl Audio 1000/1's (1) JL AUdio 450/4, Speakers: all stock speakers replaced with JL Audio XR650-CSi) and i was wondering if i needed multiple caps???? also wat cap do you think would be good for me??? thanx in advance

A capacitor will smooth out the power delivery to your system. If your lights are dimming when your bass hits this will help.

In this use, a capacitor acts as a reservoir for charge. Kind of like a buffer between your stereo system and electrical system so that when your speakers would draw more current than your car can deliver, the current is drawn from the capacitor which is always being charged. They are very cool. Get a big one that looks like a can of soda.
Like said above, you don't really need one if your lights aren't dimming when your bass hits.
