Yes atm i have a little 12v mini fridge in my bedroom for the odd sandwich and can or few bottles .. i have a stella fridge in converted shed ... maybe could go on a project for a custom build boot for it , fridge in the middle and amp one side, sub other side with 2 speakers on the top of the custom build boot ..
Or sub in the middle, 2 12v mini fridges in the corners at an angle, with speakers each side with amp build in the bottom of the build with fans for vent
im in the process of making a boot build and am incorporating a fridge in. i doubt i'll ever use it (like the xbox i wired in) but at least i'll be able to tell people i have a fridge in my car! and it'll look cool!
i have a playstation in the car with an inverter and a 7 inch LCD digtal TV all wired up to it but the problem was that i did not want my car battery going dead so i bought an extra battery and a cable that link's to the car battery and the spare battery so that the spare one never runs out and the car one never does too the spare one is in the boot with a nice little boot build can basically power anything off it. it's a good idea to do it if you work from your car alot thats why i feel comfortable in my car alot more don't have to spend money on hotels any more got it all in my car that i need!! the next thing is to retrim all the fabric the previous owner put a cig hole in the back seat then i will be comfort able!!
