I recently ventured into the Campervan world. A friend gave me a couple of older nice waterproof Polk audio speakers. Mounted them in the back of the van on a custom rubber shock mount I build from random pieces at the hardware store.

I wanted a way to power the speakers and send music via bluetooth 5. All powered off my 12v solar system. Looked around at all the 'commercial' offerings and found nothing attractive. Everything was over priced or just didn't have modern features.

So... I searched around on Amazon for the right keywords. Ended up getting one of these little class D 100w+100w amps with treble and bass knobs off Amazon for $30 [1]. Got a 12v->24v step up for $16 [2] to give the amp a bit more power and less distortion.

Works amazingly well for a fraction of the price of anything else.
