I am debating on wether to put a capcitator in my system?

I am getting installed a JL12w6 and Audiobahn A1800E amp. The amp puts out about 400 watts. Should i get a cap or no?

well.. do your lights flicker when the bass hits? if yes, then it wouldn't hurt to have a capacitor

 

If you get an alumapro 5farad cap...it'll be cheap, easy to install, and keep power problems away.
