Haven't done audio in @ 14 years now. Just picked up a DXI104 SVC. Have a limo golf cart that we take camping. Planning on dropping the speaker in the bag well under the rear seat. Need to make a custom box to fit. Not trying to blast the old ladies out of their campers, just trying to let them know I'm there. Want a good clean sound out of it for a limited radius. Should I go for a sealed or ported box? Any recommendations on what to use to make it? How to make it? Any help would be great. Thanks.
