I also have the PowerCell Cap too, the asking price is $225 for both. I had it powering my 4 speakers and a JL 12w3, so it can handle a lot of power. You can bump it for hours on end, it never overheated.
Here is a link with a review of the amp:

Either private message me or call me, my # is (925)360-3395. I really would prefer someone in San Diego, that way we could meet up and you can check the stuff out yourself. My name is Chris.
