Hi,
I have an old active sub box with two 10 inch subs, that has a plate amp that has died. I'm trying to figure out if I can find an amp board and power supply that I could get working rather than replace the plate amp (because it's probably not worth spending a lot of money on).
It appears to have had a 200 watt plate amp. The speakers are both single coil, and they are wired in parallel. When I put a multimeter on the speaker wire with both speakers connected, I get an ohm reading of 4.
Ideally I would have liked something simple like a "AIYIMA TPA3116 Subwoofer Amplifier Board TPA3116D2 Audio Amplifiers 100W Bass Output DC12-24V" with a laptop power supply, however I think 100watts isn't going to be enough considering it used to have a 200 watt plate amp.

Can anyone recommend something similar with more power? I realize I probably wouldn't be able to use a laptop power supply for something with more power, so I'm open to other suggestions for power.
Would 2 of the above boards connected to the same laptop power supply work (1 to each driver)? Or would they each need their own power supply?

There's a whole mess of them on AMAZON
Lots on Parts Express
And they aren't all that expensive. I figure by the time you gather up an ICEPower module, chassis, power supply and assorted bits and pieces, you'll have one that's about twice as expensive with fewer features.
