I have a 95 caddy deville tryin to put 2 18' in it and the space im working with is 51x32x18. Need help please

 

and what do you need help with?

 

need more info

 

power, woofers, budget?

going to run two sharks 2500.1 PSI Platform 3 fully built  and needing the best advice on the box i am going to cut a hole in the back seat where the arm rest is at to allow more air to push threw taking the 6x9's out the back deck.

Even though that is a big trunk you are still barely squeezing 18s in there. I would recommend going with 15s and to look at other options than the PSI woofers
