Ok, so I wanted to try an ABC box because I had heard some great things about them and I had just enough room to fit it in the space I was willing to sacrifice in the trunk. I know it looks like a mess but it sounds amazing. Gets super low and accurate. Loud but clean. I'm impressed.
1.3 net tuned to 33/66hz using 3" PVC with some old flared ends I had laying around. Fi BL 10" powered by a Cadence A7HC.
Starting to come together.
Side view. 14" total height, 10.75 deep. The lip on the bottom is 4" total. 2" inside and 1.25" under. Just tall enough to clear the gas tank hump. Fits like a glove and netted me another ~ .4cf over just resting it on the hump. The back seats aren't a 45* angle so I got another 3" on the top side, which was another .5cf.
Test fit pics.
Inside view of the mess of plumbing. I couldn't have gotten the tuning I wanted without porting externally.
All buttoned up and ready for a listen. Pre-carpet (obviously). I may still make a false wall which is why I didn't carpet yet.
Ok, well that's it. Like I said, it sounds great. Version 2.0 is going to be a down/forward firing set-up through the ski pass.
