Very very well. The port is pretty small but it works. When I bench tested the box the was quite a bit of port noise but when its under the back seat you dont hear it at all.
Yes it is, I test fit it in the truck tonight and ran some test tones through it from 29hz to 60hz on 1k. The results of the test were as follows: "ZACH YOU ARE 30 YEARS OLD, THAT IS EMBARRASSING, TURN THAT DOWN!" I was in the garage and she was on the other side of the house lol.
