[QUOTE="82 cutlass, post: 7204503, member: 561239"] It's going in a 92 cadillac brougham . Going to fire through the rear deck and seal it off from the trunk . I have a lot of space to work with so adjustments shouldn't be a problem with port and tuning . As for the result i'm looking for is just some loud daily SQL . How's this look ? The box is 1 cube bigger in both the ported and sealed side tuned to 50 hz.
