The box will be 2.25 Cubes at 31.9hz and will go between my back seats in my 01extra cab tacoma. This was my first time doing a flared port or any kind of kerfing. I reinforced the kerf with fiberglass resin and mat. Stay tuned to see how it turns out. I plan to have it done before monday when my amp comes in.

Looks great. What is the process for bending MDF like that?

I used Baltic Birch so it might be a little different since its's layered, but you basically make 10 or more cuts depending on how big and tight you want your radius to be. I made 5 in of cuts spaced 1/2in apart for my kurf, but it just depends on what you want to do.

The sides are painted and the top is lightly stained with about 5 coats of a protective clear coat sanded lightly inbetween each coat.

I finished the box up today. Put the sub in with bolts and T-nuts. Fiberglassed the speaker terminals, put the box/sub in the truck and bolted it down. Had to take the driver side seat out to get the box in the back. I ran all the wires for my amp. All i have to do now is wait for my amp to come it. The shipping got delayed today.

The paint is Rust-Oleum American Accents. I think the gray I have is the darkest shade of gray, but I could be wrong.

I appreciate your opinion but when you want access to the storage under the seat and the option to seat 4 people there really isn't any other place to mount it.

Thanks for the replies! UPS lost my Amp, so the search and claim process is in effect right now. It doesnt look like I will see that amp tell 2 weeks or more if at all. It was fully insured, which is good news if ups can't find it. In the mean time I picked up a Alpine mrp-m1000. The sub sounds amazing! In some songs it sound like a giant mid. It is about as loud as my old type R 12, except sounds 1000x better.

^^Thats what i thought too and the vid of my sub was over 100mb and it was only 1:10 long lol......had to cut it down a little.

motoamster13200
08-01-2008, 10:39 PM
So i positioned the box every possible way I could in the back and found that with the Sub facing either the pass or driver seat to sound the best. Facing the sub towards the back sounded a little better then firing forward in the center, but I found behind either seat to be the best. I found that firing the sub towards the back right or left window sounded the second best.

Found to sound the best: Maybe kinda bandpass effect?
