I know who manufactures the woofer. That was not the question.

There is no loud feature.

This is quite obviously an input element. I only have 2 rcas going from the deck into 3and4 (of 4) inputs on the amp.

When I run them into 1and2 I get more bass in the woofer but my 6.5s dont work at all. In 3and4 the 6.5s work half decent (no good bass, but I get highs) and the woofer is working at least. So currently Im running in the amp inputs 3and4 only.

So my question is: Why is it doing this? What happens when I get a deck with say 3 sets of preouts -- front, back, and sub? I can only plug 2 sets into the amp.... so which do I use?
Why would the power output increase from the amp as someone has said above with a new deck with decent preouts? *even if my deck is messed up... the amp should still be amplifying the wacked out singal correct?

THanks
