I just finished and installed my DC audio M3-8. I built the box out of Baltic birch (the real shit) and installed LEDs and polycarbonate. Let me know what you think. The subwoofer sounds amazing and its not even broke in yet. Hits the lows very well for an 8" sub.

The box specs are. You can see my build by clicking on the link in my sig.

Oh its in the back of a 1999 Toyota Tacoma 2wd

11.5 H

26 L

10.5 D

Gross volume 1.28

Net volume .76 this is after sub and bracing displacement.

Physical port length 30.25"

Tuning is 36.15 HZ

Port height 9"

Port width 1.5"

Port area 13.50

Port area per foot 17.85

Port ratio 1:6

I just bought a m3 8 and am in need of a box design. Your dimensions would fit my trunk perfectly. Would you be willing to post a design, or a cut/build sheet?

Right. But I found your Torres sheet in your thread and typed it in myself. I can't seem to get anywhere near .75 net tuned to 35hz myself... Waiting on an amp before I build my box but it would be awesome to have a box design ready. Mine will basically be like yours but rear facing

Well I didn't save a pic of the calculations I did. I did put the numbers back in and came up with something real close. I added 1 extra 1/2" baffle and the getting the Physical port length you enter 33 in the port length. I put in .05 for bracing and 2 common port walls. Try that. If its close to my numbers you should be close. I am sure mine isn't exact to the specs you see or even tuning unless you have a way to measure it. I don't.

Right, thanks I'll give it a try. How much power are you giving it? Sorry, 60+ pages is a lot to read thru.
