The c5's come in compnents or coax's..The reason I am recommending them is because they are the same quality.. Usually when you buy a Coax set they are cheaper because its easier for the manufacturer to produce them, and they dont generally use as good cross overs.. I just installed the 5x7 coax c5's in my mercury cougar and they sound awesome
