dude, you can only use one channel more than likely. Most 2-channel amps can only read a 4-ohm load when bridged. anyway to get a two ohm load wire it in series. Connect the neg(-) terminal on the amp to the pos(+) terminal of one of the voice coils then lead the wire to the - teminal of the voice coil then to the + again then to the - again and then to the amp's + terminal. rockford fosgate website has a wiring wizard that can explain it much better.
