GENERAL PRECAUTIONS AND INSTALLATION TIPS

Caution: Be careful not to cut or drill into gas tanks, fuel lines, brake lines, hydraulic lines, vacuum lines, or electrical wiring when working on your vehicle.

Disconnect the vehicle’s ground wire at the battery before making or breaking connections to the audio system’s power supply terminals.

Do not use the HCCA Amplifier unmounted. Failing to securely mount the amplifier can result in damage or injury, particularly in the event of an accident. An unmounted amplifier acts like a heat-seeking missile in the event of a crash. Never mount a HCCA Amplifier where it might get wet. Mount the HCCA amplifier so the wire connections will not be pulled. Route the wires where they will not be scraped, pinched or damaged in any fashion.

The +12V power supply wire must be fused as close as possible to the battery terminal, ideally within 18”. Use the recommended fuse size or circuit breaker listed in the POWER CONNECTIONS section of this manual.

If you need to replace the fuse plugged into the side of the HCCA amplifier, replace the fuse with the same size ATC type fuse that came with the amplifier. If you are not sure as to the correct value, refer to the POWER CONNECTIONS section of this manual for details. Using a higher current fuse may result in damage to the HCCA amplifier which is not covered under warranty.

NOTE: Make sure all the equipment in the system is turned off when making or breaking connections to the HCCA input RCAs or speakers terminals. Turn on the system and slowly turn up the volume control only after double checking all wire connections.

Power for systems with a single HCCA amplifier can be supplied by most any automotive electrical system. Systems with multiple amplifiers may require a higher capacity battery, alternator or the use of a storage capacitor. WE strongly recommend the use of both a WIRED! Transient Storage Capacitor and a MBR70 with an extra battery in larger stereo systems.

HCCA amplifiers generate a certain amount of heat as part of its normal operation. Be sure the area around the cooling fins is un- obstructed to allow adequate air circulation. Remember, beach blankets, last weeks laundry, school books and homework papers located on top of the amplifier, does not improve air flow.
