98' F150 ideas needed, see my pics. Rear seat bottom/centre enclosure.

[westvan_dude]

Did a bunch of work on it over the weekend. Got 80% of the mdf in. The sub mdf rings are mounted. Still have to build the seat tops either side of the subs (in the centre), seat fronts and outboard seat sides. Then build the slot vent which is going to be one convoluted m*****f***er. Finally stretch cloth over the rings, glass it all in.

So I'm maybe 25% done at this stage. Sorry no pics. Wife went on a 3wk bicycle trek and took the camera. Did get a friend's film camera and got some shots of the progress so far. Perhaps post those up next weekend if I get a chance.

Holy jeez a 3 week bike trek? Where the HELL is she riding to Alaska?!!!

Sounds like its coming together nicely though! We're awaiting scanned images...

Nairobi, Africa to somewhere south of that. http://www.tourdafrique.com/tourdafrique/

Ok boys & girls. Got pics up of the mdf work. It's finished except for the wall piece at the back/centre which will hold the amp bolted on from the backside. The modified slot port will be finished in behind the top woofer and it's backside being the piece where the amp is bolted on. More pics later.

Just a couple pieces of mdf to cut, plus measure the overall volume of the enclosure for port tuning and I can start the fiberglass work. Pretty excited so far to see it coming along. It's about 18hrs worth over 4-5days at leisurely pace. Had to change things on the fly sometimes. No setbacks yet.

Ok. Did another couple hours of work on it.

Had to calculate the vent size/design.

Had to move the top woofer ring up about 2 1/4 inches and slightly more horizontal from original positioning so it would adequately clear the fiberglass of the port where the mdf which you can see runs across and about 6" high to the backside of the top woofer ring. With the original position, the magnet/motor of the top sub would of interfered with the fiberglass of the port.

Added jpeg images #25 to #31. Last few pics show rough fleece cloth positioning. Basically I will start by stretching it over the lower front facing woofer ring (which has the mdf ring loosely placed in the pics). Fit that real nice and tight and mount the mdf finish ring to the flange ring. Then stretch it up over the top mdf flange ring and mount the outer finish ring. Then just start from the bottom, pull the fleece real tight around all edges and staple it to the routered edges.

The diagonal piece supporting the front of the top ring is only temporary so the ring doesn't flex too much while stretching cloth over it in the next step.

After that it's fiberglass resin time. I can't wait to start but tomorrow night I'm out for dinner and tonight it got late as well as the temp is dropping overnight. Right now it's just before 9pm and it's dipping down below 2deg C. Almost freezing. No good for glassing. Hope it warms up a bit over next couple days.

It worked out to about 5 1/4 cubes internal volume. Ideally I would of wanted 6cubes but oh well. Them's the breaks I guess. Will be tuned to 37hz according to Audiobahn specs. The port size is about ~20% more than my test enclosure. I had 45cu.in before, now it's 55cu.in. Not as much as I wanted and I'm sure way less than some of you guys use in comps but it's only a daily box. My box size wasn't quite ideal so didn't want to take up more interior volume as well as not wanting to move the top sub any worse than it is because the port is right behind it. The back wall is still missing, where the amp will mount. I left it off on purpose to make it easier to goop fiberglass resin on the inside of the box. Less messy that way. Will mount that mdf piece closer to the end.

Just hit my photoshare link in the previous post to see all the pics.

Here's a few more shots. Got the fleece all resined up. Time to work on adding glass to the inside.

60grit industrial sanding pads for the orbital sander make quick work of the body filler compared to the standard 60grit wood sanding pads. Also don't clog up, especially when the filler is cured 24hrs. It'll be another 2-3 evenings to finish off the body filler.
