MOUNTING THE AMP
Note: It is recommended that you make all wire connections before permanently mounting the amp.
IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before beginning the installation.
- Always wear protective eyewear when using tools.
- Choose a safe mounting location, away from moisture. Check clearances on both sides of a planned mounting surface. Be sure that screws or wires will not puncture brake lines, fuel lines, or wiring harnesses and that wire routing will not interfere with the safe vehicle operation. Use caution when drilling or cutting in the mounting area.
- Choose a location that provides enough air circulation.
- Do not mount the amplifier with the heat sink facing downward, as this interferes with cooling.
- Mount the amplifier so that it will not be damaged by the feet of backseat passengers or shifting cargo in the trunk.

CONNECTING THE REMOTE BASS CONTROLLER (CLUB A5055 ONLY)
SETTING GAIN, CROSSOVERS, AND BASS BOOST
Setting the gain
- Start with GAIN control set to minimum, and the crossover control rotated midway.
- For the front and rear channels, choose music you’re familiar with. For the subwoofer channel on the Club A5055, choose music with substantial bass content.
- Turn the volume control on your receiver to ¾ of its total output.
- Adjust the GAIN control clockwise, listening carefully to the bass output. If you hear distortion, turn the GAIN control counterclockwise to decrease the gain.
Selecting the crossover mode
On the front and rear channels, you can select your preferred crossover mode.
Choose HPF to allow only frequencies above a certain point to reach your
speakers.
Recommended if you’re using a subwoofer in your system, as it keeps low base
from your full-range speakers.
Choose LPF to allow only frequencies below a certain point to reach your
speakers.
Recommended if you’re bridging the front or rear channels to power a
subwoofer.
Choose FULL to allow all frequencies to reach your speakers. Recommended
if you’re not using a subwoofer in your system.
Note: The crossover mode for the subwoofer channel of the Club A5055 is
low-pass only.
Selecting the crossover frequency
Choose the crossover point to suit listening preferences. Turn the dials to the left to lower the crossover point and to the right to raise the crossover point. Exact crossover settings for coaxial speakers and subwoofers depend on your listening preferences.
Selecting the subwoofer phase (Club A5055 only)
Switch the PHASE back and forth to determine which setting provides the most clean bass output.
Selecting the bass boost (Club A5055 only)
Adjust the BASS-BOOST control clockwise or counterclockwise to suit your taste.

TROUBLESHOOTING
No audio and POWER INDICATOR is off.
- No voltage at BATT+ and/or REM terminals, or bad or no ground connection. Check voltages at amplifier terminals with VOM.
No audio and PROTECT INDICATOR flashes every 4 seconds.
- DC voltage on amplifier output. Amplifier may need service; see enclosed warranty card for service information.
No audio and PROTECT and POWER INDICATORS flash.
- Voltage less than 9V on BATT+ connection. Check vehicle charging system.
No audio and PROTECT INDICATOR is on.
- Amplifier is overheated. Make sure amplifier cooling is not blocked at mounting location. Or, there may be voltage greater than 16V (or less than 8.5V) on BATT+ connection. Check vehicle charging system.
Amplifier fuse keeps blowing.
- The wiring is connected incorrectly or there is a short circuit. Check wiring connections.
Distorted audio.
- Gain is not set properly. Check setting. Check wires for shorts or grounds. Amplifier or source unit may be defective.
Distorted audio and PROTECT INDICATOR flashes.
- Short circuit in speaker or wire. Remove speaker leads one at a time to locate shorted speaker or wire, and repair.
Music lacks dynamics or “punch”.
- Speakers are not connected properly. Check speaker connections for proper polarity.
Engine noise—whining or clicking—in system when the engine is on.
- Amplifier is picking up alternator noise. First, check ground connection on the amplifier – a loose or improper ground is one of the main causes for noise. Turn down gain. Move RCA audio cables away from power wires. Installing an alternator noise filter on power line between battery and alternator might also be necessary.
