    No one likes the idea of capacitor for your sub so, I never got to try it or use it. I got nothing against that particular brand but you can't find an installer who is happy to hook it up in your car. It is not happening. Don't buy it unless you really need it. I think it is a good product but not for improving sound quality or adding power to your AMP or bass.

    Purchased and had BB install this and rewire my entire stereo. Had a install done elsewhere and it was a mess. I gladly paid BB to completely rewire it. Capacitor works great. No dimming lights from pulling my battery.

    I got this capacitor and had to take it back three times the last time it was totally broke, and the bottom was blown out on it. Unreal!!! Poorly packaged.

    Maybe it was just the one I got but I doubt it. First of all when I got the product one of the holders was broke. Then I had this hooked up in my car for a bit and went too work on muy system. When I did I noticed the terminals were loose thought I had forgotten to tighten then. No that was not the problem the set screws didn't want to hold good so when I went to make sure they where tight the screw went all the way through and I have 0 gauge wire. Also when went too remove product the negative terminal moved on me so took it back for a refund. Which was a hassle because it w was after15 days. But they did take care of me.

    I had used this for my 1500 watt system and it worked great. When I went to a 2200 watt system, I found out I had to upgrade to a 3 farad as well as upgrading my vehicles charging system too.
