I was just going with and all Infinity System. The dash has the Infinity 3 1/2 REF3002CF, the rear doors are going to have the 5 1/4 component REF5000CSl, and last Infinity Kappa 10 sub. As for the front I was looking for a better speaker for SQ. After reading about CDT Audio (seems like everyone is going that route), I was thinking of gettting the CDT Audio 6 1\2 CL-62 for the front doors.
Will combining reference Infinity's mess up the SQ of the CDT's? $150 is the budget for the front doors.
Power will come from a Soundstream D'artagnan 5.1 Amplifier
