2011 Dodge Ram The new Alpine radio is a huge improvement over the factory radio. We chose the Arc Audio amplifier for its compact chassis and outstanding power. The crossovers for the front doors were neatly wired and secured to the door. To ensure a life of service, we use plastic for all our speaker adapters. The rear doors got plastic adapters, sound proofing, foam rings and new speakers. Securely mounted in the front doors, the Arc Audio woofer sounded great! The Arc Audio Black tweeter is their premier high frequency driver. The 3d printed tweet pods were just what this truck needed! This picture illustrates the “stealth” in Stealthbox. Almost no space is taken up. An incredible amount of accurate bass now inhabits this truck, thanks to the JL Audio subwoofer.
