I have an older home stereo system and i took both speakers out of the box to install into my truck, and i hook them both up and man they sound great.
But the problem lies here, they are a little to big to put the trucks speaker cover back on.

So with a little help here, i was thinking of building a box or something, or doing something with the previous box that the speakers were in, but the thing is, just putting each speaker box in the truck is so bulky.
So maybe i could build something for them.
I'm at a stand steel here, so any help is appreciated.

 

Do you have measurements of the speakers?
