Currently doing a spl install in a 94 thunderbird lx, need some help and ideas on how to get more "flow" through the car. the trunk is basically detached from cabin on this car. its completely walled off. had to drill holes through backing behind rear seat to run wires. anyone got ideas on how to get more spl into the cabin? the rear deck is sold since there is no speakers in it. and behind the rear seat is all solid.
so far my thoughts are to cut a large circle on each side of rear deck and mount a round port into the holes. and also thinking of cutting out the square in the middle of rear seat were the arm rest folds down.
any other ideas would be great.
