Description
Choose PXA1000.5 when one waterproof amplifier needs to run a complete powersports or marine system: four full-range channels plus a dedicated subwoofer channel. It delivers up to 150 watts x4 at 2 ohms and 600 watts on the 1-ohm sub channel, so it avoids adding a second amp in a tight build. It is also compatible with PXAPT programming for deeper tuning. Choose PXA400.4 when there is no sub channel needed, or a PXA monoblock when bass is being amplified separately.
