Infrasonic Filter; Troubleshooting - Rockford Fosgate Power Elite T15002 Installation And Operation Manual

ACTIVE PREAMP OUTPUT CROSSOVER (Pass-Thru)
Is used to set the crossover output for the Pass-Thru Jacks.
Placing the switch in the HP position sets the output of the Pass-Thru to the High Pass mode, enabling
frequencies above the frequency set at the main crossover to pass.
Placing the switch in the AP position sets the output of the Pass-Thru to the All Pass mode, allowing all
frequencies to pass.
Placing the switch in the LP position sets the output of the Pass-Thru to the Low Pass mode, enabling
frequencies below the frequency set at the main crossover to pass.

INFRASONIC FILTER

Placing the switch to "ON" engages a 28Hz infrasonic filter limiting the amount of low frequency
information going to the woofer. Set this to your personal preference while listening to the system one
way, then the other.
NOTE: We recommend using the infrasonic filter when using vented enclosures with this amplifier.
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. Check fuse(s) on amplifier. Replace if necessary.
3. Verify that Ground connection is connected to clean metal on the vehicle's chassis. Repair/replace if
necessary.
4. Verify there is 10.5 - 15.5 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, this is usually a sign of driving the amplifier at very high power levels without
adequate airflow around the amplifier. Shut off the system and allow to cool. Check for proper
speaker impedance, rewire if needed. Low battery voltage may also cause Thermal to light. 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.
OR
1. Use a different 12 Volt source 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.
