SPLChris

So my game plan is to do 2 twelves facing front with port facing driver side rear fender area. The box width is going to be just wide enough to accommodate the subs so a little more than 25" but would it be better to have the height about the same as the subs or would it matter, in terms of SPL? If it's around 13.5" (internal height 12") then I wouldn't be able to stack the 4" aeros. If it's 15" then I can stack them but to me, I feel as though the more streamlined shape of the other box would allow for higher SPL. The taller enclosure would be shorter on depth too, obvioulsy. I could also just be thinking about this way too much but whatever

It's worked well for me in the past so why not?

I love my SPL 15's. They are probably one of my favorite street beating subs. Mine are different because I only have the soft parts and different baskets. Is the backplate vented now?

Some buss bars under the hood and my XA3000D

I'm building up a "foundation" for a future bass race setup in my Jeep. Right now, it's just for two 15's but I would like to get some heavy duty 18's in the future once I add more power to the mix.... The rear chamber is 9 cubes tuned to 33 hz and the front chamber is big with a big port The port and subs from the rear chamber will be facing right in front of the loading wall. For anybody that asks why I used particle board....Lowe's was out of MDF, plus it was cheaper. Not a big deal to be honest. We'll start off with what was in my Jeep before: Start of the tear out...

Yeah, very little ones though. It's very cold out and rainy and it sucks. I ran all new 0 guage so I have a total of 6 runs. Knukonceptz KLMX cable. My Powerbass came back from repair! It got a whole new board. It's wired at 1.4 and it's audibly louder than my xd1800 wired at .7 I'll get some pics up when it stops raining.

It looks like the Qts of the speaker rises with each larger speaker. If that's the case, you should make an 18". I'm looking for a nice driver for open baffle use in my HT

SPL 15's for sure and I don't think building a wall would be necessary

Some hair tricks with the same setup so far. I still need more power, though. http://www.youtube.com/watch?v=988kmzEybpo with the passenger side door open, it isn't as great. http://www.youtube.com/watch?v=MLJ_vx-GrLs

Yeah, I still have a lot of stuff to do with it, if only I could find the time.

Yeah, that's my sister

SPL 15

Yeah, and remember, this is with an American Bass XD1800 so I MIGHT be getting 2000 watts. Hopefully it'll move more air once I get my XA3000D back.

Some short videoes of my 6th order wall in my Jeep. Mach 5 SPL 15's and an American Bass XD1800. My Powerbass XA3000D is in for repair. Still have a lot of tweaking and testing to get this build running full tilt. Thanks for the views! Door flex from the inside. 22 hz. http://www.youtube.com/watch?v=2kVUFE3LjUo Roof flex/wave. My camera didn't pick it up very well. It's violent, though. 33 hz. http://www.youtube.com/watch?v=xf__x8HY5As Some door flex at 20 hz. http://www.youtube.com/watch?v=oEwtb79NM-g

The rear chamber is 9.5 cubic feet tuned to 31 hz and the front chamber is ~23 cubic feet tuned to 60.

yah. It's very efficient but I think the combination of the 2 ported chambers actually lowered my rear chambers tuning frequency because it plays ungodly low and this isn't even with my XA3000D so it should be much louder once I get that back in. I need to figure out why the 30 hz region is lacking, though.

I posted this over on the Mach 5 Audio section, too. Some short videoes of my 6th order wall in my Jeep. Two Mach 5 SPL 15's and an American Bass XD1800, so not a whole lot of power. My Powerbass XA3000D is in for repair. Still have a lot of tweaking and testing to get this build running full tilt. Thanks for the views!

It's finished for now but my XA3000D blew and I have no idea why. I wanted to start testing and fine tuning it this week but I guess not If anybody wants to give me an amp that would be great!

Found my camera. I couldn't get a good angle for the rear chamber on some of the pics.

Okay, I can't find my camera but I got the baffle for the rear chamber on and most of the front chamber has a nice layer of resin and the wheel arches have been fiberglassed over. So far everything is nice and strong.

Not much done today so I didn't take any pictures. I filled in some screw holes and smoothed some stuff out with body filler. I might have to pick up some more wood tomorrow morning.

haha, there's glue. I've gone through about 3 tubes of PL adhesive and 4 tubes of liquid nails.

The loading wall has a little over eight total 2x4's Cat
