Rockford Fosgate T500-1bd 500 Watt Class-bd Mono Amplifier

The T500-1bd produces the same amount of REAL power than it's predecessor, even though it's nearly 50% smaller in size! In about the same space as a college sized history textbook, you can now use a dedicated subwoofer amplifier to drive two 4-Ohm DVC subwoofers. This amp will provide enough bass to separate you from those envious car audio geeks.
