Rockford Fosgate Prime 150 Watt 2-Channel Amplifier - R150X2

Online Only

The PRIME R150X2 is a 2-channel amplifier that can pump-out 75 Watts into both channels at 2-Ohms, making it perfect for full-range or component speakers. The R150X2 can also run in bridged/mono mode for use with subwoofers.

Rockford Fosgate amplification at an unbelievable value. The R150X2 2-channel amplifier pumps out more than enough to power a set full-range or component speakers, or you can bridge it into a 4-ohm load to produce 150 watts for a single R1S410 10" or R1S412 12" woofer.
