January 18, 201213 yr Author Thread moved.thanks...Also, I'm going to be only pushing 340RMS @ 4ohms max on the SA8-v2, and another question since my Alpine MRV-T420 is 4 ohm stable so SA-8v2 D4 is what I need? I just see on some other thread about D2 can be wired as 1ohm or 4ohm, so that made me confused. please direct me to right track! thanks...

I myself build about 6-8 enclosure for my previous setup never know about tuning it right, I just build it randomly so it would fit the sub! lol but I guess they were all around 50- 70hz which is way out of range. I been around with a few set of sound system over 9 years, never though about tuning a box!!! I heard a little but never understands from researching on other forum untill I found this forum!!! you peoples up in here ROCKS!!!Anyways, I've settle with this final sketch, since my space is limited, so the best I can do is 1 3/8" x 7 1/4" port to get probably 0.6cu ft @ 36hz with the SA-8v2 in.
