Thinking about the 15' Alpine type r sub Alpine SWR-1541D model. Would two to these do good in 99 gmc yukon 4 door. I want more spl than sq. but still clean. Could get these subs for 200 a piece new. Worth it or look somewhere else for 2 15's?? Running each sub off a mtx 6500D. 500watts rms 775watts peak. Any input would be appreciated. All i need now in my car are new subs and speakers. Subs are hard to pick. So will the alpines do nicely? thanks.
