[QUOTE="shredder2, post: 8641846, member: 674047"] Well... that's not a ton of power, so using a little less port area might be doable (possibly less length). The manufacturer minimum ported volume is 1.8ft3, so I looked at it in Winisd in an even smaller enclosure, 1.6ft3 net to be specific... and using a round to save space, for your power, you could probably get away with 2 ea 3.5" rounds 27" long. That is what sux about round ports, the port area is set and you either get too much area (which translates to an overly long port) or too little and port compression will start to happen possibly. On the other hand a slot can be sized more precisely to your power, but a slot WILL use a buncha more volume as it displaces more. Really, I'd like to know how much space you've got available and what configuration you're lookin' for. What tune you realistically want and how LOW it should go. Giving up volume will severely affect extension if taken too far. Idk how much space you've got... this was for an F350 behind the center console/drivers seat, so it was really limited on space.
