Item(s) Description/Condition:
Items are NIB, never used.
I purchased these as a project. I bought some aluminum stock and drilled and tapped for liquid cooling without having to run a bulky heatsink. I never got around to completing them, so here they are 4 boards to use as you please.


Punch Series 2-Channel Class AB Car Amplifier
RMS Power Rating:

4 ohms: 50 watts x 2 chan.
2 ohms: 100 watts x 2 chan.
Bridged, 4 ohms: 200 watts x 1 chan.

MOSFET power supply
Remote bass level input (remote level control sold separately)
LED power, thermal, and protect indicators
Tuned Bass EQ (0-18 dB bass boost at 45 Hz or 0-12 dB bass boost at 12 kHz depending on crossover selection)
On-board differential inputs eliminates noise picked up by the signal cable
2/1 channel operation
Integrated Trans•ana technology simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality.
RCA Pass-thru outputs
Featured custom designed TO-247 MOSFETs have 60% more metal tab area providing more power handling capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in most competitor's amps.
Built in NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
Cast aluminum heatsink evenly distributes excess heat across entire amplifier heatsink
Nickel-plated RCA level inputs
Nickel-plated screw terminals
Variable high-pass filter (50-500 Hz, 12 dB/octave)
Variable low-pass filter (50-500 Hz, 12 dB/octave)
CEA-2006 compliant amplifier
Frequency response: 20-20000 Hz

325 watts, Punch Series Monoblock Amplifier
RMS Power Output:

4 Ohms: 175 watts RMS x 1 chan.
2 Ohms: 325 watts RMS x 1 chan.

Variable high- and low-pass filters (40-400 Hz, 12 dB per octave)
Wired Punch Bass EQ (0-18 dB at 40 Hz)
Focused Mass Heatsink design
Removable connector cover
Special-design TO-247 MOSFETs run cooler than standard transistors
CEA-2006 compliant
Preamp inputs and outputs
