What you need to do is look below the speaker connections and it show which two terminals to use to bridge, this will be the same for both sets. Make sure you switch the input switch to front only os it will use the same signal for both subs. To do this though your subs need to be single 4 ohm, dual 2 ohm (wired in series for 4 ohms), or dual 8 ohm (wired in parallel for 4 ohms). If you need further help e-mail me at GLN305@hotmail.com

Later,

Glenn


EDIT:

I just noticed that you have the sub currently hooked up to one bridged set of channels. Treat the bottom row of terminals and top row of terminals seperately. Basically, just remove one sub from the bottom row and move up to the top, observing polarity (+ and -).
