More info
The Punch P400X1 mono amplifier is specifically designed for medium to high-powered subwoofer applications. It's variable crossover and built-in Punch EQ allow for precise tuning of Bass frequencies, and its 2-Ohm mono stability is perfect for running up to four 4-Ohm DVC subwoofers. You can also add-on the PLC2 Remote Punch Level Control to control equalization from under the dash or center console. Sized to fit under any seat, you can hide this amplifier and have them guessing where the amp is.
