So I know there have been a lot of Stereo/Sound posts going on, but I felt like bringing some closure to this thread...
I finally got around to finishing the first phase of my stereo project. I made two enclosures out of MDF whose internal volume is .3 ft^3. the same as my original "mock up". These were soundproofed internally the same as the 3/8" plywood one. Interestingly, me and my brothe are currently compiling the results of a comparison test between the two construction materials.
There are some pic's documenting the project attached.
These subs are powerful, and even just breaking them in they are more than adequate. I will not exceed half Gain on the amp for at least 20 hrs of runtime. But trust me, you do not need more than that. I'm not the type to blast my favorite techno in front of retirement homes, but I do like to here a well rounded sound and "Rock Out" as they say. haha
The bad news is that these thing really bring out the weakness of the system put in by the PO. What I have learned though, is that I will not be investing in any new speakers for the rears. As I have it right now I have them faded almost completely out, and are there only for imaging. Instead I will invest that money into an Alpine Center speaker or possibly some component tweeters for the dash. That is pretty far in the future however.

Very nice. I'm going to be tackling something like this!
I'm not worried about delamination, because I'm gonna reseal my hatch. Actually... No. I'm gonna get a different one. This one has crappy tint on it and I'm tired of it peeling. If you're gonna have a job done, don't half-*** it! Not even financially!

its pretty rough actually lol, just got a piece of cardboard, cut it to fit the space between the fenders and then made an MDF copy, then centered 2 points for speaker holes...
then just got a big sheet of carpet and trimmed it to fit tight...wood staples are your friend lol
speakers are blaupunkt 6x9s that sound excellent, have a good bump for bass, and they cost me $15 for the set NEW from fry's.
used some 1/8" steel i had laying around and made brackets for each side, they attach to the stock seatbelt bolts and also bolt to the panel. the little black nub you see is the bolt cover from the seatbelts lol

Well MDF or not, the rule of thumb when designing any sub enclosure is:
Make it strong enough, with bracing and materials, that you could give it to an elephant to play with, and it would come back ok. If you've done this, it doesn't really matter what material you use.
Oh, and no parallel walls.
Just some friendly advice from the people at JL Audio.

Nakamichi SP-80 Sub Enclosures
Made these ported enclosures 23 years ago. Just recently re-carpeted in black......AND found someone who was selling BRAND NEW IN BOX Nakamichi SP-80's for $50. Couldn't resist; so I replaced my Naks (23 yrs old) and sold them on craigslist for $50. Fit looks OEM; sound is tight, not boomy.
