Description
Fusion Signature SG-DA82000 8-Channel Marine Amplifier
The Signature SG-DA82000 is a Class D marine amplifier providing 8 full-range channels with bridgeable channel pairs. RCA inputs and accessible setup controls make it suitable for a correctly designed marine audio system using compatible speakers and a source unit with suitable pre-outs.
Power and system design
- 100 W RMS × 8 at 4 Ω, 140 W RMS × 8 at 2 Ω, or 280 W RMS × 4 bridged at 4 Ω, measured at 14.4 V DC and under 1% THD+N.
- 2000 W is the stated peak-power figure, not its continuous RMS output.
- Adjustable input sensitivity and selectable crossover filtering for each zone.
- 10.8–16 V DC operating range. This is the 12 V model, not a 24 V amplifier.
- Marine-oriented construction with a stainless-steel cover and conformal-coated circuitry.
Installation scope
This listing is for the SG-DA82000 amplifier and standard supplied installation accessories. Stereo head unit, speakers, subwoofers, RCA leads, power cabling and vessel-specific protection hardware are not a complete included system. Match speaker impedances and continuous-power handling to the selected channel arrangement, then set gains and crossovers correctly. The amplifier needs suitable ventilation and electrical protection even when fitted inside a boat.
Installation and safe use
Install in a dry, ventilated location, not exposed to water. Disconnect power before work; use the manual-specified cable gauge and near-battery protection. Maintain ignition protection by replacing the 4 × 40 A amplifier fuses only with SAE J1171-compliant fuses. Do not connect a load below 2 Ω per channel or below 4 Ω when bridged. Connect to a suitable 12 V system only. Excessive listening levels can damage hearing.
