Iam running the high end old school Mb quart 6.5 components in the doors and Mb Quart 6x9s in custom enclosures in the wall behind my seat. Iam using a 10 inch Infinity Kappa series sub running at 2ohms in a Pro Box subwoofer box. I must say the Infinity Kappas are the cleanist sub I have heard in a long time. Everyone should check them out.
