I'm gonna have to agree with the JBL plate comment. A store i worked for was a JBL dealer, and those plates were pretty impressiveI've never heard a Kicker speaker that didn't irritate my ears, regardless of the level. Now, the last time I listened to a set was many moons ago. At that time I was pretty impressed with Pioneer's Basalt cone speaker series, whatever the F it was. If JBL still made their Power Series 4x6 Plate, I would recommend that. I have JBL Power Series in my Town Car and Fireturd, best bang for your buck around.
The Kicker comment, agree to disagree maybe..... I've done some pretty impressive stuff with Kicker in customer's and personal vehicles.
But once again, just my opinion......
