if ur paying $144 for alpine type s speakers then ur getting bent over to begin with. i usually get type r's on ebay for just over $100.

as for the main topic, i havent the RFs so i cant say, but i do love the type r's in my car. however, if you go with type r components, youll need an amp to power em. i have a 60x4 alpine h/u, and when i go above like 26 volume (alpine goes up to 35 for u noobs lol) , the tweeter cuts out for its own protection.

good luck
