Inside of the Quad Cab, stock leather and suede SRT seats reside along with the factory navigation headunit which is equipped with a SIRIUS satellite radio. Scosche EFX mids and highs replaced all of the stock speakers. Two Scosche amps power those speakers as well as a custom sub box under the rear seat. Kraemer's performed all of the audio work inside the SRT-10.
Subtle? Yes; but without question, it's custom. Casey's Dodge is a perfect example of how cool a truck can be without going overboard. If you see a silver streak while you're up in Oregon, don't worry, he has insurance.
