Whats the lowest impedance I can run on a Rockford Fosgate amplifier?
The RF, Punch & Punch Power 250.1, 250.2 & 500.2 amplifiers are all rated for use to 2 ohms per channel or 4 ohms when bridged. The Power 50.1 & 50.2 amplifiers are rated for use to 1 ohm per channel or 2 ohms when bridged, although many of our customers use the 50.1 & 50.2 at 0.5 ohm per channel or 1 ohm when bridged.
