Built this over the last few evenings and just finished today. I kind of regret adding speakers/amp at last moment as I could have fit it in a much smaller package - and I regret getting 6.5" speakers since the grills overlap. It definitely sounds better than the several portable bluetooth speakers I've used and has many more options.
2 x Boss Marine 6.5" speakers
Lepai 2020A+ amplifier
Cheapo bluetooth USB audio receiver
Bussmann fuse block fed by 8ga wire, all wire to potentially high draw areas are 10 or 14 gauge wire with appropriate fuses
2 x Blue Sea Systems panel mount 12v sockets
Dual 12v sockets for inside (controlled by right switch - bluetooth adapter plugs in here)
Cheapo voltmeter controlled by left switch, powered directly from battery
Diehard 100w inverter for air mattresses and small stuff controlled by red top center switch
18 amp hour SLA battery and Sunforce 10 amp charge controller.
Tested last night, an hour of a 20w lamp through the inverter and 2 hours of extremely loud music via bluetooth and I went from a displayed 13.0 on voltmeter to 12.8. Not bad, should easily play music, run lights, and charge phones all night when camping. I have a 15w panel on my 4runner and a 100w panel on my truck, so it'll easily recharge during the day. All in a Dewalt 24" tool box, under 20lbs total.
Powered off
Everything on... Still need to do some work with black silicone around switches to stop light leaks and make more weatherworthy
The guts... I just finished and tested everything, so I'll clean up everything and shorten wire runs + put on wire loom. All connections were either crimped quick connects or soldered and double heat shrunk.
Charge controller, gotta round out the holes I cut a little more to make the tray sit perfectly like it originally did. Stupid on my behalf to have put the inverter switch so high. Also stupid was drilling the front dual 12v sockets, forgetting I had decided to lay battery in the middle for weight distribution. Oops.
