Rockford Fosgate Power T400-4 4-channel car amplifier 60 watts x 4

Rockford Fosgate Power T400-4 4-channel car amplifier 60 watts x 4 Rockford Fosgate's Power Series AmplifiersRockford Fosgate has a well-deserved reputation for building high-quality mobile audio products. Their Power Series amps occupy the top of the amplifier food chain, with fine-tuned audio controls, extreme durability, and proprietary technologies that deliver stronger, more reliable performance than most other amplifiers on the market today. Dynamic Thermal ManagementPower Series amps use Rockford Fosgate's patented, award-winning "Dynamic Thermal Management," a 3-stage cooling system that uses forced air to dissipate heat evenly across the amp and out through the large heatsinks. This results in cooler internal components, higher efficiency, and lower distortion.MEHSA is a Rockford Fosgate proprietary process that increases heat transfer from the MOSFET devices to the heatsink. This allows the heat to escape more readily from the amplifier so that the transistors stay cooler. E
