Excellent especially for the price.

Review written by Lite Skin from San Diego, CA

This cap works very well, and it looks excellent in the back of the car. My battery doesn't die, my lights don't dim, and I have a very high powered amp with a 12" w7 JL in the trunk. With components and so forth. So, I guess it's doing it's job! Oo yes, and it has a nifty litle light presentation when you open the trunk. Sweet

I installed this cap in my wife mazda millenia pushing 2 10's in a bandpass box with a mono kenwood 300w and a lightning audio on my front mids and highs.This cap works great minimizing my headlight dimming considerbly.It gives my system a very strong boost and all around sound.I liked it so good that I bought another one for my Saturn Vue.In the vue it powers a RF Power 500T which then powers 2 Kicker L5 in a ported box. This setup really pounds like you would not believe!The price was wonderful as well.Best bang for the buck!!!
