Audison Forza AF C4D 4-Channel Compact Companion Amplifier — 4 x 90W @ 4Ω, 4 x 150W @ 2Ω, Fully Bridgeable

The Audison Forza AF C4D 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 90W x 4 @ 4Ω and 150W x 4 @ 2Ω (RMS, 14.4 VDC, 1% THD, all channels driven), and bridging channel pairs gives 300W x 2 @ 4Ω. Its compact design suits installs where space is tight.

Key Features

• 4 amplified channels: 90W x 4 @ 4Ω / 150W x 4 @ 2Ω, up to 600W total
• Each channel pair can be bridged, giving 300W x 2 @ 4Ω
• Latest-generation Audison D-Class (ADT) technology with higher switching frequencies, moving noise further from the audible band
• "All Channels Driven" design: the power supply is built to deliver rated power on all channels at once
• Plug-and-play signal input harness for connecting to AF bit amplifiers
• Use alone or as a companion to Forza bit amplifiers and standalone bit processors

Power and Technical Highlights

Like the other Forza D companions, the AF C4D uses a straight-wire design without crossover filtering, leaving all signal shaping to the processor. The CEA-rated output is 90W x 4 at 4Ω (1% THD+N, 14.4 V). It has no built-in DSP.

Ideal For / System Fit

• Adding four channels to a Forza bit amplifier system in tight spaces
• Powering rear fills or a front stage from a compact amplifier
• Processor-managed systems built around a standalone bit processor

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

Authorized-dealer listings show a supplied remote in/out lead and the Forza install kit. Check the supplied kit and datasheet for exact dimensions and cable contents before planning your install, and use correct fusing and power wiring.

What's Included

1 x Audison Forza AF C4D amplifier with supplied installation kit

Precautions

• Power ratings are measured at 14.4 VDC, 1% THD, all channels driven; real output depends on the vehicle's electrical system
• Match speakers and wiring to the rated impedances to avoid overload
• 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 C4D vs. Standard 4-Channel Amplifier

Frequently Asked Questions

What is the Audison Forza AF C4D used for?
It adds four channels of power to a Forza bit amplifier or processor-managed system, in a compact chassis.

How much power does it deliver?
90W x 4 @ 4Ω and 150W x 4 @ 2Ω RMS (14.4 VDC, 1% THD, all channels driven), up to 600W total.

Can I bridge the channels?
Yes. Bridging channel pairs gives 300W x 2 @ 4Ω.

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

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.

How do I connect it to a Forza bit amplifier?
A plug-and-play signal input harness makes the connection straightforward.

What does "All Channels Driven" mean?
The amplifier's power supply is designed to deliver the rated power on all channels at the same time.

How is it different from the AF M4D?
It is more compact and lower in power (90W x 4 @ 4Ω versus 160W x 4 @ 4Ω).
