Description

Use PXAPT when a compatible PXA400.4 or PXA1000.5 needs computer-based tuning through KICKER Powersports Tune. It unlocks the amplifier's internal EQ, crossover, channel-linking and tune-storage controls without adding a separate DSP chassis. PXAPT is only the programming bridge—the processing lives inside the compatible PXA amplifier. It is not a standalone DSP and is not the programming platform for the PXA mono amps.
