I have a 03 VW Jetta fold down rear seats.
I have a sd1500d and a dd 3515 d2, and im rear firing with a rear ported box.
Should i seal (bondo/sludge/hushmatt and or some how seal) the rear deck and leave the seats down. Or cut/gut the rear deck except for the strips to hold the cover if I ever sell it. leaving me with 3 big wholes for air, and then bondo/fiberglass the reast to make it smooth and solid?... and also put the seats down or up???? once the rear deck is gutted...
Suggestions on which route to take.
