Default Subwoofer Plate Amplifier Base Plate supplier?

So I was thinking of putting together a DIY class D amplifier for a subwoofer with a few features that I imagine aren't typically found in your average amp. Probably something in the 1 to 2 kW range.

My primary interest is in the electronics/processing capabilities of the unit and not the plate portion. I was wondering if anyone knew of a supplier for buying just a standard base plate or would I be better off just buying the $99 dollar plate amp from PE and scrapping their amp section?

If nobody sells these standard chassis, does anyone know of a company that would do prototyping for such a chassis at a reasonable price in the 10 to 20 unit volume?

Thanks for any advice,

Jason

Hi Jason

Before you actually buy some custom plates you should make up a prototype unit, as you need to define the number of pots, switches, heatsinks, etc. and their placement in your design. Using a pre configured plate may lead you to making compromises in layout.

I suspect that the Class D amp may also need to be completely encased in a grounded shield to avoid RF problems.

But, it sounds like a fun project, I hope you keep us up to date with your progress. Good luck!
