Stretch the budget a bit and you could get the Dayton SA1000 which is one mighty fine sub amp and the one I use in my DBA. https://www.parts-express.com/dayton-audio-sa1000-subwoofer-amplifier-rack-mountable--300-811I'm using 2 but you really only need one of these to run four subs. That's what Tim does with his and what Duke sells with his Swarm subwoofer system.
Replacement amp for subwoofer
The 200W amps built into my 1982 a/d/s subwoofer finally gave up. It would or cost more to fix that replace.
Any suggestions under $300?
Would prefer a standalone box since no plate amplifier is going to fit in the old space.
This is downstream of the outboard crossover.
Thanks
