take it back and get you money back, caps are useless in caraudio...
1. the big 3
2. a good battery (optima or kinetik)
3. HO alt (if needed)
4. add more batteries (if still needed)
if you notice serious car audio competitors will never use a cap. they use racks of batteries for a reason. besides, for what you spend on a cap, you can easily spend it on upgrading properly. a cap will supply only short bursts of power to your amps. batteries and a good alt. will provide a constant supply to your entire car. also, a cap is useless unless you upgrade your big 3, a good battery and alt. anyways….adding an electrical component to an already struggling electrical system will only make matters worse. if you want to do some research, you can do a search here: http://www.caraudio.com/forum.
