What about going to a C2 Audio Team 1k 12"? 2 cube box tuned to 33-34 slams! Chris let me play with the prototype and it gets down and moves a lot of air!I've been waiting MONTHS for the Sundown X-8's to release, they finally start the pre-order, and they want $800 shipped for a pair. No thanks. My Tc2 15 sounds great, but I had to lose the backseat in my 2010 F-150 to fit the huge ported box. If C2 released a 500-600wrms 8", I would definitely stay on Team C2, but as of right now, I need my backseat back. Help!!!
