It doesn't need to be 2 channel then. there's a reason 95% of all sub amps are mono blocks.because its pushing 2 subs
You are very confused on speaker impedance. Dual 4ohm subs means they can each be wired to 2ohms, or 8ohms. You can also wire them together for a final load of 1ohm or 4ohms (mono). But no, you cannot wire each one to 1ohm.ok how about this MBQ 1500 vs Audioque 1200, are they both stable at 1 ohm? also my speakers are 4ohm that means i can run them at 1 ohm a peace right?
