The number of responses you've received is a direct result of the quality of the question asked and information provided. For starters, please read the Noob Posting Guidelines With the lack of information you provided, anything we say will simply be a shot in the dark. I don't know if I need to suggest a $100 5.25" 2-way component set or the $7000 Rainbow Platinum 3-way component set. We don't know what size speakers you are looking for, your budget, your goals for these speakers and setup as far as output and sound quality, which speakers you plan to replace (both front and rear or just front?), how you will be powering the speakers, if you are powering them from an external amplifier what amplifier and how much power you would be using, how you plan to install the speakers (stock location w/ no modifications, stock locations w/ modifications possible, kickpanels, etc), what music you plan on listening to, what your sound preferences are, how much experience you have w/ past products and what you like/didn't like about them, etc. It's sort of like I Robot.....In order to receive a response, you must first ask the right question.
