Page 4: Reference Power Supply Design
l o0.e REFERENCE POWER SUPPLY DESIGN The REFERENCE amplifiers employ an extremely efficient unregulated pulse- width modulated oower SUDDIV. REFERENCE amolifiers from Soundstream are rated at 12 ;olts but &e’designed to take advantage of the additional voltage available when the vehicle is running. The two major advantages of the unregulated power supply are: awesome dynamic power capabilities added continuous power with higher voltages (see chart below) -

WIRING POWER AND GROUND To ensure maximum output from your REFERENCE amplifier, use high quality, low-loss power and ground cables. The REFERENCE amplifiers will accept up to 4 gauge or 8 gauge power and ground cables. Determine from the chart below the minimum gauge power and ground wire for CIRCUIT BREAKERS/FUSES EXTERNAL... -
Page 8: Installation And Mounting
INSTALLATION AND MOUNTING 1. AMPLIFIER LOCATION The REFERENCE amplifiers employ highly efficient circuitry and a unique Chassisinkn” design to maintain lower operating temperatures. Additional cooling may be required if the amplifier is located in a tightly confined area or when driving especially low impedance loads at extremely high levels. When mounting the amplifier, it should be securely mounted to either a panel in the vehicle or an amp board or rackthat is securely mounted to the vehicle. -
