I just purchased a 400.4 Diamond amp. I hooked up my RF power components to 2 of the channels, and now i have a 10" rockford P3, 2ohm dvc sub brideged to the other 2 channels, my problem is that the amp continues to clip on me, i dont need alot of power because its all in a pickup, But can someone pleaase tell me how to wire the sub because i think i might be doing it wrong. Thanks

you need the coils of the sub wired in series for a 4 ohm load if the rear two channels are bridged.
otherwise just wire one rear channel to each coil of the sub unbridged for a stereo 2 ohm load.
that'll stop the clipping.
parallel wiring the sub makes it one ohm, then on a bridged amp it'd see half that and clip in a heartbeat.
