Knowledge is Power
Most definitly If you are using a single sub setup, and looking for SPL numbers above sound quality even though RF has no SQ, Get a 15" you have to get the 15, the 12 just wont make you smile Like the 15 will. Its all about the smile when the install is done. This guy I know has cab 1/2 chevy sonoma with 2 power 15's and 2 bd1000 he hit like 157 I wanna say, but im not positive.
