i was helped by one of the member back in UBRF…I wonder where he is right now. I would suggest not to go to local store like Circuit City or Best Buy, they sucked. Somebody here will definitely able to help you out… Too bad I sold the capacitor. It’ll be a great addition to the system. ---

if i’m not mistaken, i used 8-gauge cable for power cable… 10-gauge might not be good enough. the easiest way is to install it right away and test it.
