OPERATION

OUBLESHOOTING

NOTE:If you are having problems after installation follow the Troubleshooting procedures below.

Procedure 1: Check Amplifier for proper connections.

Verify that POWER light is on. If POWER light is on skip to Step 3, if not continue.

1. Check in-line fuse on battery positive cable. Replace if necessary.

2. Verify that Ground connection is connected to clean metal on the vehicle’s chassis. Repair/replace if

necessary.

3. Verify there is 9 to 16 Volts present at the positive battery and remote turn-on cable.Verify quality

connections for both cables at amplifier, stereo, and battery/fuseholder. Repair/replace if necessary.

Procedure 2: Protect or Thermal light is on.

1. If the Protect light is on, this is a sign of a possible short in the speaker connections. Check for

proper speaker connections and use an ohm meter to check for possible shorts in the speaker wiring.

Too low of a speaker impedance may also cause Protect to light.

2. If the Thermal light is on, check for proper speaker impedance, rewire if needed.This can also be a sign

of driving the amplifier at very high power levels without adequate airflow around the amplifier.Shut

off the system and allow amplifier to cool. Check that the vehicle charging system is maintaining

proper voltage. If the previous items do not solve the problem, a fault may be in the amplifier,call

customer service for support.

Procedure 3: Check Amplifier for audio output.

1. Verify good RCA input connections at stereo and amplifier. Check entire length of cables for kinks,

splices, etc.Test RCA inputs for AC volts with stereo on. Repair/replace if necessary.

2. Disconnect RCA input from amplifier.Connect RCA input from test stereo directly to amplifier input.

Procedure 4: Check Amplifier if you experience Turn-on Pop.

1. Disconnect input signal to amplifier and turn amplifier on and off.

2. If the noise is eliminated,connect the REMOTE lead of amplifier to source unit with a delay turn-on

module.

Use a diff

ent 12

olt sour

ce for REMOTE lead of amplifier (i.e. battery direct).

2. If the noise is eliminated,use a relay to isolate the amplifier from noisy turn-on output.

Check

Amplifier if y

ou experience excess Engine Noise.

1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.

ADJUSTING GAIN

Do the following individually for each channel.

To adjust the gain setting, turn the amplifier gains all the way down (counter-clockwise).Turn the source unit

volume up until distortion is audible and then turn it down a bit until the distortion is inaudible.This will be

about all the way up on most source units. Next,increase the amplifier gain setting until adequate volume is

achieved.

NOTE:Best signal to noise and dynamic range are realized with the gain at minimum.

CAUTION:Avoid setting the amplifier gain very high as noise and distortion will

increase significantly.

NOTE:For a more in depth setting procedure, contact Rockford Technical Support.
