Budget PA Amp for Subwoofer
I have a Crown CE2000 bridged at 4 ohm running my 21" Dayton sub, works fine but its pretty weak. Was planning on using the crown for the mains and getting something with much more power for the sub. I don't understand how pa amps ratings work, but this thing doesn't do anywhere near 2000w, id say it maybe does 500 if I had to guess. What should I be looking for as far as used pa amps, preferably less then $700 what will actually make some power. Do I need to get a "8000w" pa amp to get 2000wrms into this subwoofer or is this particular crown amp I have just a slouch? I'm thinking 3000wrms would be ideal as its rated for 2000w and with a 5" vc I'm sure it could take a little more .
