I'm looking to get some outdoor speakers to connect to via bluetooth. just for listening to music, and maybe at some point to watch a movie on a projector with the kids, so they don't have to be anything amazing.

I grabbed some pyle speakers to try out: https://www.amazon.com/dp/B01954PYG6?psc=1&ref=ppx_yo2ov_dt_b_product_details and they're sounding pretty weak. I'm assuming the max-output of 240w means it needs an amp to hit that because they actually sound worse than my Echo, even if they can get louder... the bass is just not there. can I use something like this amp? https://www.amazon.com/Pyle-Auto-4-Channel-Marine-Amplifier/dp/B072BMP3YG

a bluetooth amp would be preferable as well, as these speakers make an awful loud chime when they connect... really annoying. So I'd be happy with returning these and getting some "dumb" waterproof outdoor speakers to power w/ an amp.

thanks
