Love it so much

I did this in 4 hours (2 people) as my first box and let me tell you IT HITS. I don’t even have a good amplifier but it’s one of my best boxes I have. And it cost us lest then buying it personally. I spent about $25 on wood, $5 nails. and it was good knowing that I did this and can show it off to other’s.

Excellent SQ Enclosure

Great SQ Enclosure.... it hits the highs and LOWS equally. It doesn't seem to really peak at any one frequency, even where it is tuned to. This design requires only one sheet of any 4" x 8" material you decide to use and will fit in most medium sized trunks with an opening of 17" or greater.
