Plate amplifier DIY suggestions / plans

Hi All!

I bought a known faulty subwoofer as a bit of a project, the PSU & supporting electronics are beyond economic repair, but I quite like the chasi and the driver is in good condition - (Its a monitor audio radius 370HD for what its worth)

I'd quite like to retrofit a DIY plate amp design to its existing back plate and use it as is. are there any plans / open source PCB schematics that people recommend, looking for a minimum of 100w into 4ohms though the driver is rated upto 250w so more isn't an issue

I'm not at a level where I can design my own circuitry... (else I'd already be doing that!) - but I'd quite like to build my own DIY board where someone with a lot more understanding has done the PCB layout / schematic and I can build it up based on a recommended BOM - I see a lot of stereo designs but a little less with respect to subwoofer plate amps.


I hope you can offer some suggestions, or maybe point me in the way of a good challenge.

All the best

Dig through the Solid State forum... lots of good amp designs, many of which could easily be turned into a plate amp. Lots of the Apex designs have PCBs laid out, and many of them will be laid out such that each channel has its own PCB. Nothing too special about a sub amplifier- just choose something nice and beefy since it will be worked hard.
