Put Rockford Fosgate's elite technology and obsessive attention to detail to work in your vehicle! Their Power 250M full-range mono amplifier will have you basking in 125 watts RMS of pure power. Better yet, string together two 4-ohm subwoofers (for 250 watts RMS at 2 ohms), dial in the wired remote low-frequency boost (up to 18 dB at 45 Hz), and bring on the boom! A variable low-pass crossover (50-250 Hz at 24 dB per octave) improves performance by blocking unwanted frequencies from your speakers. The cast aluminum heatsink dissipates heat with 30% more cooling efficiency than standard heatsink designs. Heavy-duty power, ground, and speaker terminal connectors accept up to 8-gauge wire. If space is an issue in your vehicle, you can remove the amp's endcaps for a wider range of installation options.
