Connecting the Speaker Leads
To prevent short circuits or serious damage to the unit and/or speakers:
• Connect the speaker leads only as indicated in the wiring diagram. Disconnect the vehicle
battery’s negative terminal before making connections.
• Only use speakers that have impedance ratings of 4 ohms or higher and have power-handling
capabilities greater than the receiver’s stated power level.
• The unit’s internal amplifier is designed to handle a 4-ohm load on each pair of speaker leads.
• DON’T connect two speakers to a single pair of speaker leads (“in parallel”) unless both speakers
each have at least 8 ohms impedance.
• DON’T connect the left and right speaker leads to each other or to the same speakers.
• DON’T connect the front and rear speaker leads to each other or to the same speakers.
• DON’T connect the negative speaker leads to each other.
• DON’T connect the positive speaker leads to each other.
• DON’T connect any active speakers (with built-in amplifiers) to the speaker leads unless their
owner’s manuals specifically state that this is O.K.
• Cover the ends of any unused leads with electrical tape. This will prevent them from touching the
vehicle or each other and causing a short-circuit and damage to the receiver or vehicle.
Connecting the Pre-Amp Outputs to External Amplifier(s)
To prevent short circuits or serious damage to the receiver, amplifier, and/or speakers:
• Follow the amplifier’s instructions on how to connect the unit’s preamp outputs to the amplifier(s)
and connect the speaker(s) directly to the amplifier.
