Album of Fi BTL 15 Pictures I have a Btl 15 fully loaded with Cooling, HiXm coil, Inner Heat Sink, daily Driver, dual 2s. I was recently looking at my sub and found that the spiders were starting to crack. I thought maybe the motor was bending the frame and causing the coils to scrape. I had a friend post on a forum about frames bending and they all said the frame would crack and break before it would bend. I do not know if I got a faulty frame or what but my frame is bent which made the sub not be centered and caused the coils to scrape on the motor and put extra force on that side of the spider . I have pictures and measurement to show what I am talking about. Also on my I heat ring where the plastic spacer is, found when I took it apart that there were little chucks of metal ca glued to them from factory. This would also not allow the basket to sit flush. I have a 4 cubic foot box tuned to 34hz in a 1995 olds cutlass supreme with the big three upgrade, 2 yellow top batteries, one in front and one in rear, with a Hifonic bxi 2608.
