My original plan was to get one 15" alpine type r hooked up to a zx750.1, The 15" sub is like 70 or 80 bucks more then the type r 12. How much louder would the 15 be then the 12, would it be a huge difference.
it wouldnt be a HUGE diffence...and you can power the twelve with the same amp...so really up to you.. do you want to be 12" wangin or 15" wangin? THE CHOICE IS YOURS!!!!!!!!!!!!!!
