Congratulations on your purchase of a SOUND STORM LABORATORIES car audio power amplifier. D-SERIES amplifiers are designed, and engineered in the USA to the highest level of quality, and will afford you years of listening enjoyment. All D-SERIES amplifiers utilize regulated MOSFET power supplies, which assure that switching response is extremely fast and output power is clean.
Two Channel Amplifiers: D400.2, D650.2 and D1000.
Built-in Crossovers All D-SERIES amplifiers feature built-in electronic crossovers. The 2 Channel amplifiers(D400.2/D650.2/D1000.2) feature an adjustable low pass and high pass cross -overs and +12dB variable Bass Boost. The 4 Channel amplifiers(D350.4/D500.4) feature a pair of individually adjustable low pass crossovers and high pass crossovers, as well as and +12dB variable Bass Boost.
Electrical Wiring All SOUND STORM LABORATORIES D-SERIES amplifiers are equipped with easy top access screw terminals. These terminals are Nickel Plated in order to ensure excellent electrical contact, and to resist corrosion. When making electrical connections to the amplifier, please observe the following: Use at least 8 gauge or heavier wires for power and ground connections. Wire the amplifier directly to the car battery.
Low Input / Line Output Wiring If the HIGH LEVEL INPUTS are used, do not use the LOW LEVEL RCA inputs at the same time. The 2-Channel amplifiers use ONE High Level input for both channels and the 4-Channel amplifier use TWO of these connectors-one for each pair of channels.

Tri-Mode Speaker Wiring Tri-Mode Operational Output is a unique feature which allows a Crossover (Subwoofer) to Be operated in MONO mode, while the main speakers are playing in STEREO. To engage the amplifier in this mode, place the Crossover (Subwoofer) switch in the "OUT"position. Use a 100v non-polar capacitor for a high pass crossover and a wire coil inductor to block high frequencies from the Crossover (Subwoofer) as shown in the figure below.

Dual Tri-Mode Speaker Wiring Tri-Mode Operational Output is a unique feature which allows a Crossover (Subwoofer) to Be operated in MONO mode, while the main speakers are playing in STEREO. To engage the amplifier in this mode, place the Crossover (Subwoofer) switch in the "OUT" position. Use a 100v non-polar capacitor for a high pass crossover and a wire coil inductor to block high frequencies from the Crossover (Subwoofer) as shown in the figure below.
Precautions Before you drill or cut any holes, investigate your car's layout very carefully. Take care when you work near the gas tank, fuel lines, hydraulic line and electrical wiring. Do not operate the amplifier when it is un mounted. Attach all audio system components securely within the automobile to prevent damage, especially in an accident. Do not mount this amplifiers so that the wire connections are unprotected or likely to be damaged by nearby objects.
Troubleshooting Before removing your amplifier, refer to the list below and follow the suggested procedures, Always test the speakers and their wires first. No Output Confirm that all terminal strip connections are secure and tight. Check both in-line and built-in fuses. Both the "+12v" and the "REMOTE" terminals must have +12v referenced to chassis ground. Confirm that the audio signal source (car audio, equalizer, etc.) is connected and is supplying output signal.
