Product Description
System Versatility & Unmatched Performance
P400X4
The Punch P400X4 is a 4-channel amplifier producing 100 Watts into all four channels at 2-Ohm. The P400X4 is perfect for a 4-way full-range system or a 3-way system having a front stage with subwoofers on the rear channels.
The stealth top mounted control panel not only provides a sleek finished look to the amp, but it also protects the vital controls.
Our custom heat sink design uses high aluminum mass where it is needed most to maximize heat transfer from the output MOSFETS to the surrounding air, keeping the circuitry cool even under high power and output demand.
