You should have set the NORMAL/BRIDGED mode switch to, "BRIDGED." See pages 3 & 4 of the operations manual(http://www.hafler.com/techsupport/pdf/P7000_amp_man.pdf) Rockford-Fosgate can fix your amp (http://www.hafler.com/techsupport/index.asp?ID=1)
Biamping Dahlquist subwoofer
I have a Dahlquist DQ1 sub and pair of DQ10s, and wanted to biamp them to Hafler P7000 and DH220 through a Dahlquist LP-1 active crossover. I hooked up the P7000 to sub (red posts of channel 1 and 2), set switches to Normal and Biamp, used Channel 1 as input, hit Power and instantly SMOKED one of the MOFSETs in Channel 1. Expensive mistake. where did I go wrong?
