Summary: I have these in my '05 GTO bring powered by a JL 500/5 I have a set of their coaxes for rear fill. They are pricey, but the sound is breathtaking. I'm also using the Sub P25 10" in a sealed enclosure. It's the nicest system I have ever owned. Spend your money on good drivers & clean power, the neon panels & painted consoles can wait.
