I bought 2 sets for my 96 Camaro. 1 set in the sail panel and 1 set in a pair of kick panels, powered by a Lanzar Vibe 1000W amp, and i was very pleased. Sounded 10x louder and crisper than the factory Bose system. I was a Lanzar believer years ago but since Lanzar has slacked off a bit but the Opti series has re-awakened me. Combined with the Lanzar 6.5 HR6's in the doors powered off a Lanzar 360W amp the car is like a rolling concert. The bass is awesome for a 6.5, the highs are so crisp, I heard things in songs I have never heard before. Bang for the buck is well worth it. I would put these against any component system on the market today.
