Massive Audio PX4

Inside you will discover full MOSFET high grade switching devices and you can be assured your investment will last as a result of 5 way protection circuitry and LED Clipping Indicators for front & rear. Massive Audio's built-in OEM Line Converter enables installation of this Amplifier in any system as a result of its input sensitivity adjustable up to 10V RMS with our Auto Turn On circuit and there’s a 12 Volt remote output for external 12 Volt devices.

Outside you will be impressed by a smooth polished aluminum surface with the logo glowing radiantly in blue, announcing to the world you’re in possession of PRIMO equipment. The end caps feature individual adjustments for level and crossover frequency for front & rear channels, plus a 0 – 12 dB variable Bass Boost on the rear channels. Additionally, the PX4 supports a "Docking Port" to plug in an optional custom matching 4 Farad Railcap

  • You avoid incompatible radios, speakers, or wiring
  • Installation is smoother, faster, and frustration-free
  • You get the correct accessories the first time

Whether you're replacing a factory stereo or upgrading your entire audio system, the Fit Finder eliminates uncertainty.
