Post subject:  Chip-Amp based bass amplifier?

Hopefully this summer I'll be building my first bass guitar speakers and I'd like a DIY amp to go along with it. I'm curious if it's possible to build and amp that is capable of outputting at least 500 watts based on the Gainclone design? Where would I start looking for how to bridge and couple modules together? Is this even feasible?

It is possible. You could string them together forever. Could you do with 200 Watts? 300 Watts?
Well, here is a good place to start with bridging or paralleling the LM3886.

So that pdf will tell you how to build several different power levels. Some people have made a BPA300.

Yeah, getting to 500W with 68W chips will not be that simple and it will need a pretty serious power supply. Is something more efficient like Class D or Class T out of the question?

BTW - welcome to the forum.

Cheers,
