Kangaroux's 99 Pathfinder

[Kangaroux 47]

I have a build log going on over at caraudio.com but I switch stuff around so much that I hardly ever post up anything anymore. I'll just start a fresh build log on here instead and just give you guys a rundown of what I have done so far.

Vehicle: 1999 Nissan Pathfinder

Subs: 18" Xcon D2

Amps: AQ2200, Concept HP65.4

Speakers: Lanzar OPTI6PM

Headunit: Pioneer MVH-8200

Electrical: Batcap 2k under the hood, C&D 270FR in the back, 2/0 big 3

I need to go through my build log and pull up some pics but as for now I'll just post up pics of what I got done today...

Here is the setup as it sits. I had built the frame for the false floor about a month ago but never got around to actually cutting all the wood and getting it assembled.

The sub is missing because I sold my HDC3 and am currently waiting for the xcon to arrive

Gutted and started laying down the first piece

Made sure the support where I planned to put my battery and amp was was secured down well and also loctited in place.

Since the frame wasn't built to be convenient (I blame my wheel wells) I whipped out some chalk line to lay out where I needed to secure everything

Everything screwed in

Level like a mofo

I still need to make some trim pieces for the sides just so I can cover up some of the crap under the floor itself, plus I need to make a small battery holder for my C&D since I don't really like the idea of loosely having it under the false floor. I won't be using that same box you saw as that was made for an HDC3 so the specs are a bit off, plus it's too wide for my vehicle (and it's made out of MDF )

I think this is gonna be the final box design...about 7 cubes tuned to 32hz with 87 in^2 of port. I was going to do a kerf port but I have no place to setup my circular saw to do the kerfs, and doing kerfs with a table saw is just a pain in the ass, so I settled for just a big 45 instead. I want there to be absolutely 0 port noise and also have it be somewhat meter friendly.

jesse you just need to wall it man! lol

Doing a kerf with a table saw is not very hard, and I would use more port area. So far the false floor is looking good!

I really like that design. Just finished building my first enclosure over 4 cubes. I swear 11 cubes gross didn't look that big in sketchup.

I agree though a little more port area wouldn't hurt anyone. It isn't bad though. Much better than some that I see with a little 4x5 and 2 15's.

[Kangaroux 47]

I was gonna go with 100 in^2 of port (basically making my port 1" wider) but if I go with too much port it will cut off too much of the low end below tuning. So I have 2 options: tune the box lower down to ~30hz then up the port, or keep the box tuned a little higher towards 32-33 and keep the port slightly smaller. I talked with a few design guys just to double check (RAM_Designs, Robin over at BHE, DC creations) and they all agreed going slightly smaller on the port would be my best option. I want to be able to play down to 25hz without unloading too much as well.

I know it's not hard but it'd be much easier for me to just use my circular saw. Also, I don't have any fiberglass resin or anything to put on the back of the kerf to have it harden up, so I wouldn't feel very safe having the kerf with just some glue on it lol.

Wood glue works fine. I usually use resin but I have used glue without any issues.

I'll think about it then. I'll prob drop a 45 right behind it to help stiffen it up. Maybe do a test kerf on a small piece of scrap just to see how it comes out. A kerf was my original plan but I figured the 45 would be a bit more idiot proof lol

It is, but it sure isn't as pretty. If you put a 45 behind the kerf and use some titebond it won't be going anywhere.

Design take 2. Added .5" to the port width so now it's ~94 in^2. No more complaints, lol.

[ricksi30 923]

APPROVED!

[swift 501]

That's gonna be nice

[ssh 924]

The color red absorbs wavelengths over twenty two feet (80hz and below) by upwards of 30%, so your definitely going to want to use neon green instead.

I'm just fucking with ya.

I'm just pucking with ya.

Lol! That works in my favor, I was only gonna use this as a midbass anyways lmao

looking good

[Kangaroux 47]

looking good

Thanks! Now the question is...do I have enough scrap wood here that I will need 1 sheet or two, lol

[Kangaroux 47]

Pics of the vehicle/setup as it sits:

Once I get the materials for it I'm going to run 2 pieces of threaded rod that go through the little battery cage and attach to the bottom of the false floor. Then I'll take a piece of scrap wood or thin metal or something and run that between the 2 rods so it holds down the battery .

This looks so much better man...

Yep should sound pretty good. Once these paypal funds clear I'll be able to get some wood for the box, woot.

[Kangaroux 47]

Did a test on some scrap wood here. First time ever doing a kerf port. Came out pretty good imo.

[StreetLegal 119]

Looks like a pro

[ssh 924]

Yeah man, it came out great.

[Sencheezy 689]

Wow nice

[Kangaroux 47]

Thanks. That was a 3.5" kerf. The one I'm doing for my box is a 6", lol. Gonna be real fun cutting that..
