This connection provides +12V main power to the amplifier. 4Ω minbe fused within 12" of the battery.
9. 10. Battery and ground connections to the vehicle should be made with crimped ring terminals of the appropriate size (surface area is what counts;) soldering the terminals after crimping is also recommended. Due to the high-frequency MOSFET switching power supply, filtering the power cable is not generally required (remember that the amp can’t deliver full output if the power supply is restricted.
Troubleshooting Tips Symptom Probable Cause Specifications Action To Take Audio cycles on and off Thermal protection engages when amplifier heat sink temperature exceeds 85° C (185° F). Make sure there is proper ventilation for amplifier and improve ventilation as needed. Loose or poor audio input. Check line level connections and repair or replace as needed. Loose power connections. Check power wires and ground connections and repair or replace as needed.
