Pros
  • 1556W RMS at 1 ohm at 14.4V for a compact chassis
  • 92.5% efficiency at 4 ohms keeps current draw and heat down
  • Temperature-controlled fan plus thermal protection
  • Selectable LPF and subsonic filters with 24dB slopes

Questions and answers

Is the PX1500.1D worth it?
At $180.99 it is cheap for a 1-ohm-rated monoblock with fan cooling and 24dB crossovers. It makes sense if you already have a subwoofer and a charging system that holds near 14.4V.
Does it really make 1556 watts?
That figure is RMS at 1 ohm at 14.4V, so it assumes a healthy alternator and short, thick power wire. Expect less output at 2 ohms and at lower voltage.
Can it run a 1-ohm subwoofer?
Yes, the amp is rated down to 1 ohm. Check that your sub's final impedance is 1 ohm and upgrade wiring and grounds to match the current draw.
What crossovers does it have?
It has a selectable low-pass filter and a subsonic filter, both with 24dB slopes. The subsonic filter protects the sub below tuning in ported boxes.
Does it come with a bass knob?
Bass control is listed as a feature, so a remote level knob is part of the package. Confirm the cable length suits where you plan to mount it.
When is it cheapest?
The only price recorded since November 1, 2026 is $180.99 at Genius Audio USA. With one store listing it, discounts are unlikely, so watch for direct sales from the brand.
