Re: What amp would better power this sub?
PA Mofos are 2 ohm impedance per coil. So you should be getting ~200 wRMS out of your Rockford amp.
note: For the record, that's a cool old RF amp. I wouldn't just toss it on craigslist, unless it's in bad condition.
Upgrading to the MTX 6500D would mean running it at 4 ohms - which gives you 250 wRMS. Not really worth your time.
If you have an old Mofo,
It's rated above 2000w RMS, but I'd feed it between 1000-1500. Audioque's 1200 is on sale for $230, Hifonics bxi1210d is ~$200... lots of good choices out there.
If you have the new Mofo,
It's rated at 3000wMAX, so I'd keep 750-1000wRMS, considering the way PA rates their stuff.
Just make sure whichever amp you choose is either:
- a mono amp, rated to 1 ohm
- a 2 channel amp, bridgeable at 4 ohm
