About the Fusion SG-DA61500

Tough marine performance

Fusion's Signature Series marine amps are made to deliver power reliably in the most challenging conditions. They're designed to resist moisture while putting out the power your music needs to be heard clearly over the wind and waves. This Signature Series SG-DA61500 six-channel amplifier delivers 100 watts RMS to each of your Zone 1, 2, and 3 speakers, so you'll get plenty of sound wherever you are onboard.

Tough marine performance

Fusion's Signature Series marine amps are made to deliver power reliably in the most challenging conditions. They're designed to resist moisture while putting out the power your music needs to be heard clearly over the wind and waves. This Signature Series SG-DA61500 six-channel amplifier delivers 100 watts RMS to each of your Zone 1, 2, and 3 speakers, so you'll get plenty of sound wherever you are onboard.

Multiple configurations

You can also use the amp in 5-channel mode, powering four speakers in Zones 1 and 2 while sending 280 watt RMS to a subwoofer with the Zone 3 channels bridged. Or you could use it to power 3 high-performance tower speakers with 240 watts each. Separate high- and low-pass crossovers for each Zone let you adjust the tone for each listening area. A bass boost on the Zone 3 channels will punch up the bass when you're using those channels to power a sub. 

Tough and good looking

The stylish stainless-steel front panel resists corrosion, plus it adds an undeniable touch of style to your installation. The amp's rugged aluminum alloy chassis acts as a heat sink, dissipating heat and increasing efficiency. A conformal-coated circuit board and water-resistant design ensure that this marine-rated amp will stand up to conditions that turn lesser electronics into ballast. As part of Fusion's True Marine line, the SG-DA61500 is backed by a 3-year warranty.

Features

Marine Amplifier: The Fusion SG-DA61500 six-channel marine amplifier is effectively three full range 2-channel amps built into one chassis. Each pair of channels is independently bridgeable, so the amp can be wired as 6-channel, 5-channel, 4-channel, or 3-channel. Each 2-channel section of the amp (inputs, outputs and controls) is labeled as a zone; Zone 1, Zone 2, and Zone 3. The amp's conformal-coated PCB (printed circuit board) protects it against the harsh marine environment. The amp's removable stainless steel top cover protects the control panel on top and the connection panel on the side. Its one-piece die-cast heat sink helps to dissipate heat from the internal components to provide greater reliability and longer sustained power output.

Class-D Amplifier Technology: The SG-DA61500 features a high efficiency Class-D design with these output specifications (14.4 volt power supply, <1% THD+N):

  • Power:
    • 4Ω: 100 watts RMS x 6
    • 2Ω: 140 watts RMS x 6
    • Bridged (4Ω): 280 watts RMS x 3
  • Signal to Noise Ratio:
    • @ Rated Power: 85 dB (4Ω)
    • @ 1 Watt: 53.1 dB (4Ω)

Protection Circuitry: The amp is equipped with circuitry to keep it operating safely. The circuitry protects against overheating (thermal), reversed power polarity, over/under voltage, and short circuited output conditions.

Connections:

  • RCA Inputs: three pair of stereo RCA inputs; Zone 1, Zone 2, and Zone 3
  • Speaker Outputs: six pair of set-screw terminals; the terminals will accept up to 10-gauge wire; the included 2.5mm Allen wrench is used to tighten/loosen the set screws
  • Power: set-screw terminal; accepts up to 1/0-gauge wire; the included 3mm Allen wrench is used to tighten/loosen the set screws
  • Ground: set-screw terminal; accepts up to 1/0-gauge wire; the included 3mm Allen wrench is used to tighten/loosen the set screws
  • Remote Turn-on: set-screw terminal; accepts up to 10-gauge wire; the included 2.5mm Allen wrench is used to tighten/loosen the set screws
  • Fuses: three 40-amp ATC fuses are mounted on the side of the amp

Controls: There are independent controls for each zone, located on the top panel under the removable stainless steel cover. (A 3mm Allen wrench is included to remove the cover screws.) A flat-head screwdriver (not included) is required to adjust the rotary controls. The controls include:

  • Level: rotary controls; continuously variable from 300mV to 8V (RMS)
  • Crossover Frequency: rotary controls; continuously variable from 32 Hz to 320 Hz
  • Crossover Selector: 3-position switches; select low-pass, high-pass, or full range (crossover bypassed)
  • Bass Boost: rotary control for Zone 3 only; variable from 0 to +12dB, centered at 45 Hz

Q
I am looking for a marine amp that will push six speakers and a sub what options do I have?
[ Jim  May 14, 2019 ]

A
There are a lot of amps that can power six speakers and a sub including this Fusion amp. The amp you should get will vary depending on the needs for the speakers and the sub. I recommend contacting an advisor on 1-800-324-9695 to discuss your speakers and sub to see if we have an amp that can power them My Bio: https://www.crutchfield.com/bio/Paul
