Massive Audio PX4-100 Watts x 4 @ 4 Ohm, 300 Watts Features

• WHATS IN THE BOX | A powerful multi-channel amplifier, beautifully finished in polished aluminum that you can count on for rigorous competition and flexible and affordable enough to use as any system anchor. PRIMO is our flagship line of Amplifiers. As a result of the PX4’s configuration flexibility you have the ability to design your system around it without sacrificing sound quality.

• MASSIVE FEATURES & VALUE | PX4 Power is conservatively rated at 150w x 4 @ 2 Ohm RMS / 100w x 4 @ 4 Ohm RMS / 300w x 2 @ 4 Ohm Bridged, Freq Response: 15Hz ~ 25KHz. The PX4 is a Full Range Digital Design for high efficiency and has our Advanced 5 Way Protection Circuitry to prevent accidental thermal overload, impedance, voltage, short circuit, and clipping. Additionally, the PX4 supports a "Docking Port" to plug in an optional custom matching 4 Farad Railcap Booster (RCX).

• WHY YOU NEED THIS | Clipping LED Indicators for front & rear channels. Individual adjustments for level and crossover frequency for front & rear channels, plus a 0 – 12 dB variable Bass Boost on the rear channels. Built-In OEM Line Converter eliminating the need for additional components and their associated cost. Built-in Noise Reduction Circuitry, Auto Sensing Turn-On Function, 12V Remote Output for External Devices. Top it off with X1 & X10 Switching for greater frequency control.

• 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.

About Massive Audio PX4-100 Watts X 4 @ 4 Ohm, 300 Watts

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 PX4 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 PX4 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).
