How do you like the sound? Box looks good. For these cars, if you don't do 4th order ported through rear deck, you're at the mercy of the trunk, which as you know, sucks for sound. You have to do everything you can to allow sound to enter the cabin. I swapped out my backseat to one that has the armrest, and cut out the material behind the armrest, when it's in the up position. You can also remove the stock speakers if you haven't already, to allow more sound into the cabin.
