There are coaxial speakers with built in crossovers and there are coaxial and component speakers with seperate crossovers. Where are you guys installing your crossovers? If I had a setup such as a 4 channel amp and 2 pairs of 5x7's with seperate crossovers, do I just stuff them in the doors somewhere or what? Or would it just be better to run some 5x7's with built in crossovers. This system would have no subs now or later, ever. I have been looking at some coaxial JBL's. MSRP in Canadian money would be $250/pr. for some with seperate crossovers and $150/pr. with built in crossovers. What do you think?
