18 XXX box that will fit in my avenger?

l*w*h/1728=feet^3

Do your own calculations. Build a box out of cardboard or styrofoam...if it fits then start building, if it doesnt...crunch some more numbers.

 
fiberglass mold of the entire trunk wit hthe baffle on top sub facing up. Thing is that is going to cost alot more than $20..a lot
I have 2 sheets of 3/4 MDF already. (two 4' x 8' sheets). I wish i could fiberglass... but i have no idea how to even start that junk. What if i basically used my entire trunk as the box? I mean like... put a baffle facing my back seat, moved back enough that the sub wouldnt flex and hit the back seat though. When i didnt have a backseat rider i could pull down my seat. Of course, i dont have the money to use all that trunk sealer stuff. Shit is expensive.

I was thinking i could just cut a square to fit into where my spair is. Build up from there.... But i thought it would be really hard to glue the wood and everything since i would be building it inside of my trunk. A sealed box can be any shape right?I dont want to waste money by building a box then having it sound like shit.

 
just do some volume calculations and see what you come up with. RE says 4.2 cu. ft. for a sealed 18xxx. if you can fit that in there, then go for it. most likely you will have a problem getting the box inside the trunk. do your seats fold down? you can put it in that way too.

 
Yeah my seats fold down... i dont know if i could get it through the doors though. I just need a calculation thats the 4.2 and ill make it out of cardboard. I need LxWxH dimensions to make it is all.... if it fits then ill build it. If i can go bigger i will.
