Can the SR 6.600 power a three-way active front stage?

Yes. Its six channels and adjustable crossover sections support an active three-way front configuration. Channel power can be allocated across woofer, midrange, and tweeter duties.

Can I use this amplifier with a factory radio?

Yes. The SR 6.600 has speaker-level inputs as well as RCA preamp inputs. It also includes USS and selectable ART automatic turn-on functionality for compatible OEM-system integration.

Can channels 5 and 6 run a subwoofer?

Yes. Channels 5 and 6 can be bridged for 370 W RMS at 4 ohms or 600 W RMS at 2 ohms. Use a subwoofer load that meets the specified 2-ohm minimum for the bridged 5/6 pair.

What speaker impedances can this amplifier handle?

Channels 1-4 are stable down to 2 ohms, while channels 5-6 are stable down to 1 ohm. Bridged channels 1/2 and 3/4 require 4 ohms minimum, and bridged channels 5/6 require 2 ohms minimum.

Is a bass remote included?

Audison lists the VCR-S2 remote level control as an optional accessory. It adjusts the output level for channels 5/6 and connects using a Molex connector.

Does the SR 6.600 have a digital audio input?

No. The specified input types are preamp-level and speaker-level analog inputs. Digital input is not listed for this model.

The Audison SR 6.600 is a six-channel Class D car audio amplifier designed for multi-speaker systems that need flexible channel allocation. It can power a fully active three-way front stage, front and rear speakers, or a front system with a bridged subwoofer channel. Its channel layout makes it suitable for system upgrades where one amplifier must cover several speaker duties.

With 1,120 watts RMS total power, the SR 6.600 provides staggered output capability across its channel groups. Channels 1 through 4 are suited to higher-power speaker applications, while channels 5 and 6 support low-impedance operation or bridging for subwoofer duty. This arrangement supports systems that need more output for woofers while retaining dedicated amplification for midrange and tweeter channels.

Audison D-Class technology combines switching amplification with a compact chassis and rated efficiency above 87 percent. The amplifier has a specified bandwidth of 10 Hz to 42 kHz and is presented by Audison as Hi-Res Audio certified. It is intended for listeners building a detailed, actively crossed-over system without using a large conventional amplifier.

The SR 6.600 accepts both RCA preamp-level signals and speaker-level signals, allowing it to work with aftermarket receivers or many factory audio systems. Its balanced, high-noise-rejection inputs and Universal Speakers Simulator are designed for OEM-integration applications. Selectable ART automatic turn-on can switch the amplifier on from compatible BTL speaker outputs when using speaker-level inputs.

Built-in crossover networks provide full-range, high-pass, low-pass, and band-pass options across the channel groups. This enables active three-way, front/rear/subwoofer, and other multi-channel configurations without requiring an external analog crossover. An optional Audison VCR-S2 remote level control can adjust the channel 5/6 output level from the dashboard.

Key Features

Six-Channel Layout: Supports active front stages, front/rear systems, and subwoofer configurations.
1,120W RMS Total Power: Provides substantial combined output across all six channels.
Bridgeable Channel Pairs: Allows channels 5/6 to power a subwoofer at 2 ohms.
Dual Input Compatibility: Accepts RCA preamp signals and speaker-level factory-radio signals.
Adjustable Crossovers: Enables high-pass, low-pass, and band-pass system tuning.
ART And USS Integration: Supports factory-source turn-on and speaker-load compatibility.

Design & Installation

The SR 6.600 uses an extruded aluminum chassis with fanless convection cooling. Its compact enclosure measures 314 x 155 x 47.4 mm and weighs 2.52 kg. The Class D platform is specified at greater than 87 percent efficiency.

Install the amplifier on a secure surface with adequate ventilation and use properly fused power, ground, remote, signal, and speaker wiring. Match speaker loads to the applicable channel minimums: 2 ohms for channels 1-4, 1 ohm for channels 5-6, 4 ohms when bridging channels 1/2 or 3/4, and 2 ohms when bridging channels 5/6. Configure the onboard filters for the selected system layout, and use the optional VCR-S2 if dashboard adjustment of the channel 5/6 level is desired.
