Hey new here but looking for advice on an enclosure idea I thought of. I currently have one SDC2.5 15 in a 4.5 cu ft enclosure after displacements, it has 132 sq in of port area tuned to 38 Hz powered by a MTX TC 6001. I am thinking about adding another. The enclosure sits in my gutted back seat of my 03 neon, I was thinking either seal off trunk from the car and build a bigger enclosure same design or build an enclosure in the back seat and then have the port extend back into the trunk and leave it open there are no 6x9's installed at the moment. Also have 100 sq ft of deadner.
