Well, some of you might have seen me mention the custom subwoofer box I'm working on for the stang....here are some teaser pics (battery died after these two were taken). I test fitted it tonight where the back of the back seat used to be and it fits very well (though snug). Tomorrow I'll be putting the carpeting on and possibly testing it out prior to installing it. I'll snap some more pictures when the camera batteries are charged. The box is sealed and fits 2 10's and 2 6.5's and has 1.39 cu. ft per sub. The two subs are separated and the 6.5's are isolated from the subs. The frequency response should be relatively flat. The speakers are just what I had laying around...nothing too fancy as I'm tight on money at the moment. I plan on powering the subs with a 600w peak amp (~150w RMS X 2 ch @ 2 ohm (subs are dual voice coil)). The 6.5's are going to be powered with some cheapo 110w peak noname amp I was given a while ago.
