Accurate, detailed, efficient sound

Nicely detailed sound. From the few 6x8 and 6.5" I listened to in Crutchfield's local store, these had the most detailed, nuanced sound, especially in the vocal frequencies. Powered off of an aftermarket Sony head unit, they sound great and controlled even at higher volumes. It's a 6x8 with no amp in my case, so naturally the lower frequencies may be a little lacking for some. I added a Kicker 10" powered subwoofer to complete the package, and am very happy with the major upgrade over the factory Ford speakers. Install was a breeze, plug & play with the supplied (free) wiring harness adapters. What you get for what you pay, I'm not sure how you could do any better.

Pros: Clarity Ease of install Power efficiency Price
