Jeep YJ roll bar speaker boxes for 5.25" speaker

thingiverse

You're looking at speaker boxes for 5.25" speakers in various designs. They were designed to clamp onto the roll bar of a Jeep YJ. The YJ roll bar measured 58mm, so these will clamp onto any 58mm bar. They were created with M4 washers, nuts & screws in the clamp portion. The M4 nuts press fit into the speaker body (use your screw and a washer to pull them in). The little lid portion was designed for use with M2 washers, nuts & screws. The nuts slide in the inside wall, then hot glued to stay in place. I have a cheap 20 watt stereo, so these were designed as powered speakers. I'm installing a cheap 100 watt inline amp that I found on eBay: https://www.ebay.com/itm/DC-12V-24V-TPA3116-D2-100W-Mono-Channel-Digital-Audio-Power-Amplifier-Board-N3K4/183905025196?epid=13023215407&hash=item2ad197fcac:g:vfsAAOSwZwdcf7z2 Paired with these speakers: https://www.amazon.com/gp/product/B00022OBO2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I'm also installing 12v outlet & usb outlets: https://www.amazon.com/gp/product/B07DH7R6MS/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 I've got everything installed, it fits great and works! I have all four of my speakers amplified with the amps listed above. The only way I could get them to work was by not connecting the negative speaker in from the stereo. I also had to adjust the volume down on all four amps. So far, I'm really impressed by how loud this system is. I've posted the Fusion 360 export of my design, so it's assumed to be editable – something I've never done before.
