Bobwires Killer Audio System
 
Hello All

I'm a stereo guy, and here's my shop truck in the works. It's going to be tuned up for some serious sound quality, with some crazy bass thrown in there as well.

I'm installing a Sony head, JL Slash amps, Hybrid Legatia speakers, and DD 8" subs.



Box comes first. (2) DD 1508's at 2.2ft3 tuned to 34hz.

I'm keeping it really simple, no molding into any trim or anything.

3" PVC for ports. This box is tuned at the advice of Ray West - a serious SPL guy.

Gooped up good. I did put a brace in the middle, by the way.

Nice even glue dripping. I hate caulking the back seam, and on this box it would be impossible. I opted for a buttload of wood glue instead of gorilla.

This box is screwed along the side edges. This is the first box I've screwed together since I was 17 and got a compressor and nail gun.... I did it because I want to put a pretty large radius on the sides and not risk screwing up my honking router bit. Those puppies aren't cheap.

Plaster for the shape. I'm sick of slaving away on bondo..... well actually I just had all day to tinker on 3 different things, so I figured I had the time to wait for plaster to dry and I could take advantage of it's ease of sanding. It's plenty tough for this job.

Seat all the way back

Scooted up where I actually drive this thing. I sit farther forward than usual because of the long clutch travel.

I considered doing these end caps several different ways, with several different shapes, but here's what I did. I rounded all the edges, but kept the insert corners sharp. top and bottom of the box are 3/4" radius, sides are actually a 1-1/4" radius but not with the bit all the way down. I think it will look pretty cool.

I was also going to do the port insert later, but figured I'd just hog it out and fill it all up/in when the insert is removed. I'll level out the side with the ports quite a ways. It's coming along nicely but leaving my shop in the biggest cloud of dust I've had in a long time. Not since I was sanding plaster with my 8" rotary on the display.

The ridiculous cloud of dust.

In retrospect, the plaster wasn't even close to strong enough for this aggressive of an insert, So i knocked the end caps off and redid the profiles with duraglass.

I couldn't help it, had to shoot some primer. I'll get the last bit of filler on there and have it blocked out and wrapped up as soon as I can....

I blasted them with Urethane primer today. I had some sitting around thickening up.... figured I'd use it to black out the box.

I'm not going to wrap it until I have the console built and the transitions figured out.

Oh wow, thats VERY nice!
It is going to be nice to have those 2 speakers sitting a few inches away from you :)

I am running 2 10" subs @ 400W RMS in my current car... my new Quad Cab RAM is only going to have 1 9" sub, not sure what its at... I don't know how well I am going to adjust to that lol.

This is a little different that sticking a pair of subs behind the seat. I'm really into box design, and I even consulted a real expert (Serious SPL competitior) for this one. It's tuned up to get the best response in this particular truck. Forward firing subs, side firing port, loaded off the side wall. I expect to hit 145 DB with a pair of 8's.

Very nice build sir. Been checking out your logs over at DIYMA too. Everyone can trust this guy, he's good.

SS4Luck 01-11-2012 06:31 AM

Gotta love the DD stuff...

Id imagine with Ray throwing his hand in this (design wise) you will at some point put it on a TL and get a score?

That's impressive right there, nice build on the box. Hope to see some video of it to get an idea what it sounds like.
