TROUBLESHOOTING

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 REM lead of amplifier to source unit with a delay turn-on module.

OR

1.Use a different 12 Volt source for REM 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.

Procedure 5: Check Amplifier if you experience excess Engine Noise.

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

OR

2.Bypass any and all electrical components between the stereo and the amplifier(s). Connect stereo directly to input of amplifier. If noise goes away the unit being bypassed is the cause of the noise.

OR

3.Remove existing ground wires for all electrical components. Reground wires to different locations. Verify that grounding location is clean, shiny metal free of paint, rust etc.

OR

4.Add secondary ground cable from negative battery terminal to the chassis metal or engine block of vehicle.

OR

5.Have alternator and battery load tested by your mechanic.Verify good working order of vehicle electrical system including distributor, spark plugs, spark plug wires, voltage regulator etc.

P325.I, P600..I bd specifications

Rockford Fosgate has long been synonymous with high-performance audio equipment, and their series of amplifiers, namely the P325.1 and P600.1bd, continue to uphold this legacy. Engineered to deliver uncompromising sound quality and powerful output, these amplifiers are ideal for car audio enthusiasts looking to elevate their in-car listening experience.

The P325.1 is a compact monoblock amplifier designed to supply robust power to subwoofers. With a power output of 325 watts RMS at 2 ohms, it strikes an excellent balance between size and performance. This amplifier features a high-pass crossover that can be used to filter out unwanted frequencies, ensuring that your subwoofer receives only the bass it needs to perform optimally. The adjustable subsonic filter further allows users to tune the amplifier according to their specific audio preferences, ensuring clean and powerful bass reproduction.

On the other hand, the P600.1bd ups the ante with a significant power output of 600 watts RMS at 1 ohm, making it well-suited for larger subwoofers or more demanding sound systems. This amplifier incorporates Rockford Fosgate's innovative Class BD technology, which allows for higher efficiency and improved thermal performance. The Class BD design also minimizes distortion at higher volumes, rendering a cleaner sound that preserves the integrity of the audio source. The P600.1bd includes a variable low-pass filter and phase switch, enabling users to fine-tune the soundstage according to their vehicle's acoustics.

Both amplifiers are designed with premium components, featuring a cast aluminum chassis that not only enhances durability but also promotes effective heat dissipation. This is crucial for ensuring the longevity of the amplifiers during prolonged use. Additionally, these models come equipped with RCA inputs, screw-type terminals for easy wiring, and a sleek design that fits seamlessly into any vehicle setup.

In conclusion, the Rockford Fosgate P325.1 and P600.1bd amplifiers are exceptional choices for audio aficionados seeking powerful and precise sound amplification. With advanced technology, customizable settings, and robust construction, they stand out as reliable components for any high-performance car audio system. Whether you are a casual listener or a dedicated audiophile, these amplifiers offer a pathway to an enhanced listening experience on the road.
