Electrical Wiring All SOUND STORM S-SERIES amplifiers are equipped with easy top access screw terminals. These terminals are 14K Gold 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. For the ground connection, use the shortest possible wire to a good chas

Tri-Way 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. Please review the table below for inductor and

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 unmounted. 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 in a pinche a condition, or likely to be damaged by nearby objects. Be

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 tonight. 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 au
