Living up to that standard we proudly present another entry in the Massive Audio PRIMO series of \u003ca href=\"https:\/\/www.massiveaudio.com\/collections\/amplifiers\/class-d\"\u003eClass D Amplifiers\u003c\/a\u003e, designed and engineered in the USA. This PRIMO PX4 is a multi-channel Amplifier that easily delivers up to 150 Watts RMS to each of 4 Channels @ 2Ω and 300 Watts to 2 Channels @ 4Ω. All PRIMO series amps use Mil Spec PCBs with Surface Mount Devices.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInside\u003c\/strong\u003e you will discover full MOSFET high grade switching devices and you can be assured your investment will last as a result of our 5 way protection circuitry and  LED Clipping Indicators for front \u0026amp; rear. Our 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. Adding to its “street cred” is its compliance with the Consumer Technology Association’s CTA 2006 Standards for \u003ca href=\"https:\/\/www.massiveaudio.com\/collections\/amplifiers\/\"\u003eCar Audio Amplifiers\u003c\/a\u003e. Not only does it comply it actually outperforms these stringent standards All models are pretested and will outperform their published CTA 2006 rating. I.C.P.
