Hi guys, I currently have two regular pioneer 10" shallow mount subs in the back of my dodge ram. i was planning on upgrading to the the premium pioneer 10"s ( the s4 model) this friday. I have a rocksford fosgate r500 d series amp. the old subs run at around 200-250 rms i belive, and the new ones would run at 300 rms. my amp pushes out 500 raw rms. i am not sure ( despite what they told me at the aduio shop) wether or not my amp will be enough to properly power the new subs. The guy says whenever he does a system with the preium pioneers he uses the r500 amp. However, i'd hate to upgrade only to see a minimal change in performance. does anyone have any kind of experience with this sort of thing?
