Thomas, I have two questions for you. First one should be fairly easy, I have a three way Diamond Audio Hex set up. 6.5, 4, and tweets. In my old car I had them with the 4's and tweets in a kickpanel and the 6.5's in the door. This worked out well but Im not willing to spend that kind of cash right now for the kicks in the Supra, plus that panel always got in the way. Right now I have the 4's in the doors, the tweets in the platic panels in the kick facing at an angle somewhat condusive for imaging, and the 6.5's in the back speaker location. I still have them crossed over the same way I had them when they were all up front in my old car. Should I build a small enclosure for the 4's and the 6.5's instead of having them thrown in there with no enclosure? Also should I keeop the 6.5 crossed over as just a mid bass driver with it being seperated in the back by itself? Any suggestions would be appreciated. My second thing is I want to put some subs in the back. Would it be possible to get either a 10" of maybe 2 8" subs on the sides where the foam pieces are without removing the spare. There seems to be alot of room, both depth and width, on the drivers side, and a little less on the pass. side where the jack set is(there is much less depth on this side). I have had people tell me that the Kicker L7 8's actually pound pretty good and have real low air specs. Let me know what you think. Thanks.
