Massive Audio EX44N 4-Channel Amplifier

Product Overview

Build a four-speaker car audio system with the Massive Audio EX44N 4-channel amplifier, rated at 100W RMS per channel at 4 ohms. Its flexible input options, built-in OEM line converter, and crossover controls support a range of system setups.

Use all four channels for front and rear speakers, or bridge channels for higher output to a compatible mono driver. The compact chassis measures 9.5 x 5.9 x 2.1 inches.

Key Features & Benefits

• Flexible power options: Choose four-channel operation or bridged output to suit your system design.
• Hi- and low-level inputs: The 0.4–10V input range accepts speaker-level or RCA signals.
• Built-in OEM line converter: Connect a factory radio without adding a separate line converter.
• Auto turn-on: DC-offset sensing can reduce the need for a separate turn-on wire with compatible head units.
• Adjustable sound controls: Bass boost and X10 crossover controls help tailor the signal to your system.

Technical Specifications

• Bass boost: Adjustable from 0–12 dB.
• X10 crossover controls: On 2/4/5-channel models, the switch supports high-pass or low-pass filtering at 3 kHz (up or down), or band-pass operation.
• Additional outputs: Includes a 12V output for external devices or processors and a separate 12V-trigger-style output to power or enable other devices.
• Rail CAP connection: Optional docking input supports a Massive Rail CAP up to approximately 4 Farads.
• Design and protection: Class AB design, full MOSFET switching, Mil-Spec double-sided PCB with SMD parts, built-in noise reduction circuitry, Next Gen Advanced 5-Way Protection, and CTA-2006 compliance.

Why Choose This Product?

The EX44N offers flexible channel use for a multi-speaker car audio build. Its listed ratings support four-channel operation at 4 ohms or 2 ohms, as well as bridged operation for a compatible mono load. Input flexibility and onboard signal controls give you options when integrating the amplifier into a system.

Installation & Compatibility Notes

Check available mounting space against the 9.5 x 5.9 x 2.1-inch chassis dimensions. Match speaker loads to the listed minimums: 2 ohms per channel in stereo and 4 ohms in bridged mode.

The inputs accept high-level or low-level signals across the listed 0.4–10V range. Auto turn-on uses DC-offset music sensing; confirm it suits your head unit and installation. The source lists no bass remote.

Frequently Asked Questions

How much RMS power does the EX44N deliver?

It is rated at 100W x 4 at 4 ohms and 200W x 4 at 2 ohms. The listed bridged RMS rating is 400W x 2.

What is the minimum speaker load?

The minimum is 2 ohms per channel in stereo or 4 ohms when bridged.

Can I connect a factory radio?

The built-in OEM line converter accepts speaker-level signals, and the amplifier also accepts low-level RCA inputs.

Can I adjust the bass from the driver’s seat?

A bass remote is not listed for this model. Bass boost is adjustable from 0–12 dB on the amplifier.

What should I check before mounting it?

Compare the chassis dimensions with your available space and confirm your speaker loads match the amplifier’s minimum impedance ratings.
