Just thought I'd chime in... haven't been around any forums lately, and I haven't talked to Scott/Nick/Shawn for a couple of months. I'm glad to see business is still booming. I purchased my first 18" fully-loaded BTL in August I believe... waited for my 20.1 to come in. Got the 20.1... and we built a 10 cube ported box, tuned to 30hz in the trunk of my 1996 Chrysler LHS. I gained close to 6 decibels going from an 18" SX and an Orion 1200D to an 18" BTL and a 20.1. My buddies Tom (forceofwill) and Robin (iamamp3pimp) with the BTL: After a local show (not sanctioned): It was loud, lasted me a few months... but then I had the desire to do a wall. It started out as a small idea, but quickly things came together. I got together with my friends Ruckus and Tom and we started to build a wall. We didn't do enough research, and before the wall was finished, we knew what we did wouldn't be sufficient. I got together with Tom weeks after and following advice of someone else, we went to work on a 9 cube box for the wall. After it was half done, we realized how small that really was.. and Scott advised me it would probably be a failure. I had made the commitment to go to the CarAudio.com Florida meet on December 30th... and we were already quickly getting into December. I was talking to my buddy Jon Kent, the owner of Epicenter Designs in Bradenton, FL about my car and what my goals were. I wanted a 150 decibel daily driver, and I wanted an indestructible wall. He told me he could meet the deadline, so I got my car up to him and he got to work. I did a lot of research, and got advice from a lot of people... Shawn, Nick, Noah, TommyK, Scott... and I passed on everything I could to Jon. Jacob from Sundown Audio supplied me with a sponsorship and I picked up four SAZ-1500Ds from him. Scott got me the second BTL. I took a bus up to Jon's house and stayed with him for a few days and finished up the wall with him. I drove up to Shawn's place, bought some batteries from him and he helped me out with the battery box. We didn't test the coils, and wound up blowing a BTL... no one's fault, just a combination of things overlooked. Scott did his best to get me a recone quick, and I attempted my first recone. It was a success! I had reconed my first sub, and it worked great. I purchased a DMM and everything necessary to remedy the situation a few weeks later, and I got to hear the wall fully-functional for the first time. I took out the TermLab and tested different things... and, well, let the pictures speak... What happened? The car couldn't handle everything. The transmission started slipping and leaking transmission fluid, the power steering fluid was leaking, the rack and pinion needed to be replaced, the A/C was leaking freon, the sunroof was popped out from the pressure and the car had so much additional weight in the back that my exhaust was scraping the road. I sold everything, and purchased my dream truck... a 2002 Chevrolet Blazer, one I had admired for months. I just got my 15" SSDs (with copper coils) the other day, and I'm planning my next system. Let's see how loud a Blazer can get!
