Profile's California mono amplifier punches out 300 watts of primo power for your subwoofer setup — without a big price tag! And the amp's accuracy is impressive, thanks to its ultra-quick MOSFET power supply.

Profile built in a low-pass crossover (40-130 Hz at 12 dB per octave) so you can adjust low-frequency response to suit your vehicle. For maximum slam, engage the variable bass boost (0-12 dB, centered at 45 Hz).

High-level speaker-level and low-level preamp inputs simplify connection to any type of system. The 600MSX will readily accept up to 4-gauge power and ground wires, and up to 6-gauge speaker wire!
