Well I recently switched out my Viper D1200 for a Sundown SAZ-1500 and all I can say is wow! I am running 2 Type Rs in a TCAB and it is friggin insane...I am wondering if I should upgrad to 3 12" Type Rs or go to 2 15" with the power I have...I am going for all out SPL and the type Rs are my choice of sub, so what would you do?
