i have an RF 1051s amp and would like to bridge this amp into 4ohm (1050wrms) and parallel 2 infinity kappa perfect subs (400wrms/1600wrms) so my question is, would this setup out powered my subs? HELP! i wouldn't want to smoke neither of my toys.
You would be pushing it. It also depends on the enclosure you put them in. A tight sealed enclosure will be better with the power than a big ported one. I'd either run the subs at 4 ohms on each channel for 265RMS, or you can bridge it if you are VERY careful not to push the subs too hard.
