Got mine today and my parents got me some wallmart 8inch sub box that were clearnced. i saw them before they gave them to me, they hide them in the wrong place and asked me to get something from where they were at. I really need to build boxes for the 8's they are the TangBand 740's from DOTD. In the sealed boxes (wally boxes) with each 8 wired sieres to the amp, means the amp was putting out about 75w/rms. Using the sub input with the +6db @40hz. Things were rattling on walls and cabints... All i hear was nice clean bass till i ran it full tilt and hear some type of escaping air do to the cheap box. The plastic handles were just screwed in just like the backplate with no "speaker sealent tape". I used some THX mp3's i got a while back online. My fav on the subs was the Dino come walking and kills its prey... all i need now is 2 more of the sub and good 350watt or higher amp. I was suprised just how loud the subs got with just 75watts est.
