the last system i had in my 97 blazer was 2 L7 12's on an old school 1500.1 (sharkfin) which hit 144.6 (TL). I sold it am now looking at new subs. My buddy works at best buy as an installer and like the Alpine type r 15's (He drives a 01 Jimmy with 4 15" T1's so he knows loud) When i went to the two local shops they both suggested Alpine R's. One shop offered me the 15's for 350.00, Which is a great price. Oh and i need the new setup by this Sunday for a local show. The L7's won me third last time, will the R 15's be louder?
