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

Good question.
I don't know. I usually DIY amps. It is very good for me, with a low cost and good effect.
I design a PCB board and send it to

Only $7 I got my PCB assembled amps board for 5 pcs.
+ One on the Parts Express. All kinds of goodies, and options if they are out of stock.

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.
