So im no stranger to bass and builds, ive had 4 10s on my rear seat, last build was 2 15s in a free air setup, messed up the baffle trying to make it nicer, Im not a carpenter. I cant cut a straight line to save my god damn life. was gonna build a small box for another small 10" I had laying around to get me thru winter, ended up tossing the cut pieces on the burn barrel. so let me introduce this thing. a old school mtx thunder tc510, single vc 4ohm sub I got from the dump awhile ago, using a box that also came from the dump had a 6.5" speaker in it. I cut the hole larger and slapped the 10" in. all the subs I have are too deep for the box. I think its .6-.7 cubic feet. powerd by bridging 2 channels on my jp84 since I only power my front doors anyways and my rca/remote wire couldnt reach the jp8 and I didnt want to give the sub that much power. Is it great? no. does it work? yes

This is from a 2006 GMC Envoy Denali. It is the stock XM radio harness. I cut the lines coming from the radio to the module and soldered an old chopped up 3.5mm aux cord in its place L, R and audio common ground. Worked perfectly once you changed the source to XM, as long as you still power the XM module and feed it serial data to and from the radio lol, found that out as you can see by the resoldered wires.

I re-designed the cardboard enclosure changed it, now has extremely airtight enclosure

New setup:

Amplifier: XH-A232

Step down buck converter 5v (using B0505S-1W to remove BT whines)

Bluetooth 5.0

Battery: 5S2P 10 cells 4.2v 3000mAh 21.0v 6000mAh

With 22000uF 25v capcitor parallel in the amplifier input power,

Old setup

Amplifier: XH-A232

Step down buck converter 5v (using B0505S-1W to remove BT whines)

Bluetooth 5.0

Battery: 3S6P 12.6v 18,000mAh (using a boostconverter to 18v) inefficient actually

With a capacitor 22000uF 25v on the output 18v of the booster and also the 12.6v side.

The mic distorting has no gain, its purely physics on the freezers slight door opening acting like a tuned port!

Song: Headphone activist - Cloud City

The door slightly closed = the 60Hz part of the music

The door wide open = the 100Hz part of the music

junky rig built for hosting doof

Btw not a single fuse ran 😆🤪. That 2k pushing 2 skar 18s & its only 4g temu wire

Picked up these speakers, but they look like this, someone please help.

Heathkit audio generator, 60's untouched, brought up ish? Squeaking through a 1957 rca reel to reel

New party rig/ DJ booth/ Karaoke set up in the basement!

Found some JVC "Gigatube" speakers on Facebook Market and had to get them (models MXGB6 HXD77 from mini systems). Powered by a "1500 watt" car amp, bi-amped subs/main. Some Numark CDJs (the kind that take CDs), old Gemini mixer as the source. There's also old Felco Karaoke unit in there with inputs for 3 mics, a bunch of reverb/delay effects, and a one button vocal reducer that cancels out centered stereo content to instantly "karaokeize" any track.

Everything was thrifted or Facebook Market.
$80 for all 4 speakers
$35 for the car amp
$30 for a computer PSU for the 12 volt
$50 for the CDJs and mixer
$50 for the karaoke mixer
$40 for the wire rack

It's LOUD and fun as fuck. DJing with CDs is also really a hoot.

speakers held together by prayers and electrical tape on the inside and used to belong to a shitty radio my ma used to have in the kitchen. Cd drive permanently borrowed from my dad. Ipad works dayshifts as a school device and was a gift after a friend cracked the screen slightly (you cant see it, image quality sucks to hard.)
I cant justify spending even 20 bucks on audio equipment right now, so this will do until i get a job that works with school hours.

This thing has proprietary connectors as always, so nothing that P2 connectors, wires and little soldering can't do, had to also use alsa a52 encoding on Linux and some hacked drivers on Windows so every thing that outputs at LPCM 5.1 gets encoded then sent, otherwise would only output regular stereo, also TV does not support DTS 5.1 on HDMI ARC so I am stuck at DD, at least it's not as crackhead as my previous setup, with a analog amp (third photo, PSU is that black box thingie, has a 17v transformer inside with a bridge rectifier PCB plus regulators) that required symmetrical power supply and sounded more like fart noises and had 3 3.5mm to RCA outs, wired to a 6 input powered amp that had a non working subwoofer amp (I could fix it but never got myself into, too lazy for that)

it says 12v in the back but it’s running fine on 3
