You need to know the trunk opening as that's the limit to what will fit. Can you go through the rear seat? What kind of car/year?

Once you have a solid idea of what should fit I'd build a "test" box out of 1x2's, so it's just a frame of the actual box you'd want to build. If it fits then you're golden.

I had the same problem a few years back on my beamer. Here's what I did, worked out good for me.

Pull the rear seat out top and bottom. Take a sawzall and cut out the steel on the back wall. If ya can try and keep the seat brackets in place on the back wall when cutting, if not make a brackets for it later. You can keep the metal ya cut out around in case ya want to put it back in but I didn't, ya don't need it I just tossed it. Slide your box in, might have to take out your front seats depending on size of box. Buy some flat stock steel and make a few braces for support that go up and down the opening. Put your seats back in and your good to go.

x2 as that will honestly be the easiest way to do it, unless you're comfortable building the box in the trunk.

Thats actually a really good idea... im really surprised i didnt think abou that... i considered cutting the steel wall out and making it a wall off but because the battery sits there i couldnt do that and i didnt want to have a 4 door car that sat 2 ppl lol and i never though of bolting brackets back in place for support ...

thats definately the best idea i have heard yet but if there is anyone who can give me demensions for a box so i can just slide it in i would rather do that...

thanks a lot injected 54
