Here's a link to a few bare board amps with bluetooth that should do a good job if you want to do a full integration job or a pre-built all in one with a remote as a convenient bolt in option. These amps have wired and bluetooth inputs and can power both standard 8 ohm speakers and 4 ohm vehicle speakers. These are by no means audiophile quality amplifiers however I have a basic 2 channel one hooked up to a pair of Sony monitors as my computer and have no complaints about the sound quality.


How many and what size speakers is the cabinet cut for?
Parts express is good place to find speakers and other components.

Beyond replacement parts I would look into baffling and adding some additional internal panels for better acoustic quality and, since you live in an apartment, sound isolation.


That looks like it will be a fun project, good luck and keep us up to date.

Thanks for your reply. I'm not sure about a metal tab connected to ground. This is the amp. Best I could tell I think this is the same one too?

I had a pair of speakers and sub on the shelf from another project that fell through so I decided to make use of them.

speakers


subwoofer


amp to power them


battery dock for m12 batteries


25 watt solar panel


converter for solar from 22v down to 12.4


volt/watt meter to monitor solar/battery


Dimensions are 24 wide 10 high and 6 deep so it’s fairly big. I never took pictures of the wiring inside but it’s not complicated at all. I think it weighs about 25-30 pounds. It’s no lightweight
