Re: Pioneer TS-D6902R vs Alpine SPR-69 vs CDT HD-690CFX
The CDT 6x9s are 3.5" deep, and according to the Metra fitment guide you have 3.5" of mounting depth. They will need a good amplifier to get the best punch to the bass. 100W x2 will be great. They use silk dome tweeters for smooth sound on the midrange and treble. You'll also need to do sound deadening, of course.
