Amazing sound very clear and crisp sound. Great choice for my anniversary camaro project put two sets of these in no mods necessary. Then followed up with 6x9 gto 928s in the back and this system is beginning to come to life

Loved the speakers! I installed them in my 2006 Acura TL, and with slight modifications they fit perfectly and sounded great. They give off a clear sound and would definitely recommend to anyone looking to purchase these speakers.

Really, really, very nice speakers. The balance between bass and highs are excellent. The bass is solid, not a 'woof' bass. The highs are crisp and not overly bright. I find little to no need to change the bass/high balances. That's a pretty good indication of accuracy in the design. There is normally less bass during cold weather until the car/truck warms up. For the money, these are a package that is extremely difficult to beat. If I needed to, I still find them worth buying again.
