^^^^^^^this. ill bet money its this or the outputs i have the rca's plugged in to the top left and bottom left inputs im pretty sure thats right correct? also yes as of now i just guessed on the gains. i cant get ahold of an o scope or anything of the sort until monday. but my point is, it should still put out sound lol its not even close to being as loud as my t1500 was on my subs. turn your gain up a little more! lol whats ur box tuned at?
