How's it going guys/gals. Just found this site from a buddy over on stangbangerz.com, of course after i've already began the construction of my rear seat delete/stereo install. I have a 93 Mustang Lx hatch, and i have everything listed in my sig, and am going to attempt to build a box out of 3/4" MDF for the rear section where the Alpine 12" type r 2 ohm sub will be mounted, and powered by an Alpine MRP-T757 2 channel sub. The rest of my speakers are powered by my Alpine MRP-F345 amp. Just thought i'd say whats up, and if any of you wanna steer me in the right direction to building my tire well sub box, that would be great, i know basically nothing about stereo's.

Also wanted to add, that i'm using 10 guage wire for the subs, Memphis RCA's for the amps, 16 guage for the speakers, and will also be looking around on here, on how to hard wire my Sirius Sportster Radio with my headunit. Also have a 170 amp alternator.

You want some input on building the box? What model sub do you have...is it this? https://www.alpine-usa.com/en/products/product.php?model=SWR-1222D

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Wow. Gutted the entire interior, eh? Are you planning on putting down some dynamat? Now would be the time to do it!

Your insulation foam stensil looks good. Are you going to completely seal the enclosure with fiberglass?

I would love some input on building this box.

Welcome to the12volt. :-)

I actually didn't gut the interior, it never had any to begin with. I will be putting all of it back in within the next two weeks. The only thing i'm putting under the carpet is the factory insulation stuff under the seat, i'm trying to keep weight down. I didn't plan on making the enclosure with fiberglass. My plans are to just finish up the stencils, and trace them onto my 3/4" MDF that i bought, and 1/2" MDF for the front half, cut it out, carpet it, and stick it in there. Does the sub need to be enclosed or anything, or can i just screw it into that hole i cut out?

Also what are you guys using to make the carpet fit cleanly? I'm wanting this to look like ford did it.

The sub does not need a typical enclosure, but the front should be entirely sealed off from the back. If you do not do this cancellation will occur and less than optimal performance will result.

The easiest way to obtain the seal is to build an enclosure. I would build a fiberglass enclosure into the wheel well and use your MDF as the front baffle.

On the other hand, if you're just doing this for looks, continue as planned. :-)

Build your sub box as shown under "optimum vented box" in the manual. I checked it out in a box-building program and this will give you the best response in your limited space. Because of your space confinement, build the slotted port on the outside of the containment. You can extend it along the floor. I suggest you use strictly 3/4" MDF or fiberglass of equivalent rigidity. And I strongly encourage you to use damping on the floor, lid, and some of the sidewall areas of the trunk to minimize the noise that the sheet metal will make...regardless of weight gain.

I'm not sure what manual you are refering to?

I'm only running one Type R, and the weight from the rear seat delete, cancels out what i have added so far. If i add more weight, i'll be going over what it was originally. I guess i could if i had to, but i prefer not to.

Stevdart is referring to the manual for your subwoofers. It is likely available online.

Also, i'm not familiar with what "build the slotted port on the outside of the containment, extend it along the floor", means. Do you have any pictures of this?

Anyone have any experience hardwiring their sirius radio?

Can i just build a square "box" underneath the sub, and be done?

I meant to say "enclosure". It's just saying that you don't have to build the port into the box. This sub calls for a long port, so you can build it outside the box if you're pressed for space. Just follow the general rules of venting: leave a space at each end of the port of at least a few inches.
