Why the hell can't I get any sound out of my D3.  Wired speaker outputs are fine. I did a search, tried the bypass, the initial menu etc...nothing.      I have a old fosgate punch 100 that I wanna use to power up my system in my 99 mustang.  I want to bypass the mach460 stuff power the door tweeters off the deck, the punch will drive 4 6x8's and the bass tube will have a LPF on it also off the amp.  Right now, I cant' get any sound out of the rca's tho.  I tried front, rear and sub pre outs.  I even tried to wire up sub out only to an amp with the "wired" speaker outputs and I still got nothing.  What did I wire up wrong?
