WHATS IN THE BOX | A compact yet powerful 4 channel amplifier and a part of our flagship PRIMO line of Amplifiers. Beautifully finished in a polished aluminum with our logo glowing radiantly in Blue. As a result of the PX4R’s configuration flexibility you have the ability to design your system around it without sacrificing sound quality.
MASSIVE FEATURES & VALUE | PX4R Power is conservatively rated at 350w x 4 @ 2 Ohm RMS / 250w x 4 @ 4 Ohm RMS / 700w x 2 @ 4 Ohm Bridged, Freq: 10Hz ~ 2kHz. The PX4R is a Full Range Digital Design and has our Advanced 5 Way Protection Circuitry to prevent accidental thermal overload, impedance, voltage, short circuit, and clipping. Additionally, the PX4R supports a "Docking Port" to plug in an optional custom matching 4 Farad Railcap Booster (RCX). X1 / X10 Crossover Switching.
WHY YOU NEED THIS | This amplifier represents true value in every sense. Additional features include a built-in OEM Line Converter with input sensitivity adjustable up to 10V RMS for use with any system including those with factory head units. This feature eliminates the additional cost of adding outboard devices. Built-in Noise Reduction Circuitry, Auto Sensing Turn-On Function, 12V Remote Output for External Devices (Hi-Inputs), and Mil Spec Double Sided PCB design with SMD parts.
QUALITY TESTED AND GUARANTEED TO GO BEYOND RATED POWER| Each Massive Audio PRIMO Amplifier is compliant with the Consumer Technology Association’s CTA 2006 Standards for Car Audio Amplifiers. 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. (In Car Performance) is the main design goal Amplifier is guaranteed to meet and often exceed its rated power under typical use.
SATISFACTION GUARANTEED | Since 1999, Massive Audio has been an industry leader in high performance audio products. Massive Audio laid its roots in high quality audio reproduction through in-house engineering and a dedication to customers.
When something is called "PRIMO" it has to be the best! So Massive Audio released "Primo Series" amplifiers. Simply the best for audiophiles behind a wheel! PRIMO amps use Mil Spec PCBs, SMD parts, 5 way protection, full MOSFET high grade switching devices and comply with the “World Wide Standards”, “ROHS”, “E-Mark” and are CTA2006 Compliant. The PX4S features Built-In OEM Line Converters @ up to 10V In with ATO (Auto Turn On / no turn on wire needed) and 12V out. Clip front and rear LED indicators further let you fine tune your system safely. The PX4R comes in a polished aluminum fin-less heat sink with a blue back lit logo. Only top quality 1% resistors, caps, connectors complete the "no compromise design". Each model supports a "Docking Port" to plug in an optional custom matching 4 Farad Railcap Booster (RCX).
