well, most of the time, but nto always
I personally dont liek the RF comps, i prefer the infinities, teh alpine type r's (make sure you ahve a dwide enuf doorfor them, as they will only fit ina few vehicles) but i dont really liek the Rockfords. Try JL, Infinity, Alpine, and a whole bunch others, hopefulkly someone out there can throw out some more names.
The RF's are decent, but in my eyes, over priced for what you are getting.
