Audison Forza AF M4D 4-Channel Companion Amplifier — 4 x 160W @ 4Ω, 4 x 260W @ 2Ω, Fully Bridgeable

The Audison Forza AF M4D is a compact 4-channel Class D amplifier that adds clean power to Forza bit DSP amplifiers or to a system managed by a standalone bit processor. It delivers 160W x 4 @ 4Ω and 260W x 4 @ 2Ω (RMS, 14.4 VDC, 1% THD, all channels driven), and bridging channel pairs gives 520W x 2 @ 4Ω. The straight-wire design keeps the signal path clean, and the audio band extends to 40 kHz for Hi-Res playback.

Key Features

• 4 amplified channels: 160W x 4 @ 4Ω / 260W x 4 @ 2Ω, up to 1040W total
• Each channel pair can be bridged, giving 520W x 2 @ 4Ω
• Latest-generation Audison D-Class (ADT) technology with 83% efficiency at rated power
• Audio band extended up to 40 kHz (10 Hz – 42 kHz bandwidth), earning High-Resolution certification
• Plug-and-play signal input harness for AF bit amplifiers, plus Pre-In and Speaker-In inputs
• Automatic remote turn-on from the speaker-level signal

Power and Technical Highlights

THD+N is 0.05% (1 kHz, 4Ω, 70% rated power), damping factor is 160 and signal-to-noise ratio is 103 dBA. Supply is 11–15 VDC with 2 x 30A fuses, with a maximum current draw of around 47 A at 14.4 VDC. Minimum load is 2Ω with four channels driven, or 4Ω per bridged pair. Weight is about 2.04 kg. There is no built-in DSP or crossover.

Ideal For / System Fit

• Expanding a Forza bit amplifier system with four more channels
• Driving front or rear stages in a processor-managed active system
• Bridged to run two higher-power speakers or a pair of midbass drivers

Not a stand-alone tuning solution: it has no DSP or crossover, so it needs a processor or Forza bit amplifier in front of it.

Installation Note

The chassis measures 240 x 47 x 156 mm (9.44 x 1.85 x 6.14 in). Authorized-dealer listings show a supplied kit with 4-channel speaker-out and speaker-in cables, a Pre-In cable, a remote in/out lead and the Forza install kit.

What's Included

1 x Audison Forza AF M4D amplifier with supplied installation cables

Precautions

• Power ratings are measured at 14.4 VDC, 1% THD, all channels driven; real output depends on the vehicle's electrical system
• Do not run loads below 2Ω per channel, or 4Ω per bridged pair
• Professional installation with proper fusing, grounding and wiring is strongly recommended
• Use with a DSP or processor for crossover and EQ; the amplifier has none built in

Audison Forza AF M4D vs. Standard 4-Channel Amplifier

Frequently Asked Questions

What is the Audison Forza AF M4D used for?
It adds four channels of power to a Forza bit amplifier or processor-controlled system.

How much power does it deliver?
160W x 4 @ 4Ω and 260W x 4 @ 2Ω RMS (14.4 VDC, 1% THD, all channels driven).

Can I bridge the channels?
Yes. Bridging channel pairs gives 520W x 2 @ 4Ω.

Does it have a built-in DSP?
No. It is a straight-wire companion amplifier and relies on a processor for DSP functions.

What inputs does it have?
Pre-In and Speaker-In, with a plug-and-play harness for connecting to AF bit amplifiers.

Can I use it with a standalone processor?
Yes. It works with systems managed by a standalone bit processor such as the bit One HD Virtuoso.

Is it Hi-Res compatible?
Its audio band extends up to 40 kHz, which earns Audison's High-Resolution certification.

How efficient is it?
83% at rated power (4Ω, all channels driven).
