My R speakers tear up my buddys subs, especially when you focus the bass on the 6x9s. The door rattle is terrible though. Cant wait to get R subs, might spring for Xs but It will be a while. So I do back the Rs
i've had both type r's, s types, and x type speakers and subs in my trep. X type by far is the best. They sound amazing. You wont regret spending the extra cash. I really didn't notice alot of diffrence between the s and r's. S types a pretty good and an excellent value. Go to a local shop and listen to all three and see what you think. Then order from ikesound.com, best prices your gonna find. they sell 'em for pennies over wholesale.
