Default So I got this idea....car audio home theater!

Alright guys so I thought up this (slightly) crazy thought of using a bunch of cheap car audio equipment bought off here, to make a stereo type setup in my room! To say this now, I know the car and home are VERY different environments, acoustically, and I know that I won't get the best sound quality from a stereo of this nature. Soo this is more for shits and giggles and something to do.
But there are several problems with having car audio in the house like this, the BIGGEST challenge will be getting a constant 12 volt current to everything. My solution for this would be using a decent sized battery and basically keeping a charger on it at all times, at least while I'm playing the stereo. This SHOULD keep everything going, but I'm sure it would put a strain on the battery. But ANYWAY.......
My plan is....
To get an old HU, along with some speakers, older sub, and a couple amps.....One 4 or 2 chan and a mono for subs. I was thinking of building like a box out of like 1/2" MDF?? Or similar material to mount the headunit in and putting a 12 volt battery inside of that to power the amps, and on the top or outside of the box I could mount the amps and run all the wires through the inside of the box, see where I'm going with this? Maybe paint it a nice black and clean all the wires up to get it looking nice. The box wouldn't be huge, just big enough to house the HU and battery.
Basically I just like the idea of having a HU, subs etc. in my room to listen to music on, since I like listening to music in my ride so much, I figured this would be something cool to do.
Let me know what you guys think of this, or if any of you have ever heard of anyone doing anything like this. Thank you for reading

You can use some subs, and some of the speakers from like parts express, but I wouldn't use headunits or anything like that. A pretty cheap home receiver will have 10x the processing capabilities of car stuff. People have run power inverters to run amps etc, but you aren't going to be able to run them long off of a battery. You could run a headunit with a couple speakers off a deep cycle for a pretty long time though.

Yeah I've heard of power inverters, and that seems to be the optimal way to power all the stuff. But I'm just trying to think of ways I can run this stuff the cheapest way possible. You guys don't think if I were to run a charger on a battery, at all times while the stereo was on, would be able to keep up? I don't plan on doing anything super crazy, maybe like 500 watts for the sub and maybe 200 for the highs/mids.
And yeah a home stereo receiver does seem to be a better option than a head unit. Any cheap receivers anyone can suggest? I just think the look of a nice colorful HU would be appealing in my room lol.

No. Battery won't push enough juice for long. Even using an inverter, my friends amp clipped badly and he didn't have 500 watts. This was also 20 years ago so the technology is better I'm sure

I used to think about this too. My idea was to get a small electric motor that i could plug into a wall and run a car alternator with it to power the battery. This may sound dumb but always wondered if it would work lol

This also works to heat your room and provide a fire hazard. It's cheaper, safer, and easier to use equipment meant for 110/120 ACV (not including speakers).

Just a hint here: the more times you have to transform power from one state into another, the more waste is produced (usually in the form of heat).

get a dc power supply diagram online, or go to your local hardware shop and look for the power supply that powers halogen lights for your living room that's 12v DC, I've used it before to power tools that require 6 or 12v DC (ie. replace the rechargeable batteries), works well and cheap.
