Simply plug the 6- pin modular cable into the amplifier and then into the Remote Input Level Control to activate the circuit. 50 250 500 Power Min Max 12 PowerPlus Amplifiers Troubleshooting Problem Possible Cause Corrective Action Amplifier does not turn on No power to +12V terminal Check fuse(s) No power to REM terminal Check head unit fuse(s) and wiring Blown main fuse at battery Replace fuse and identify cause of failure Blown fuse at amplifier Replace fuse and identify cause of failure Faulty ground Re- ground main power ground to bare metal chassis Volume control too sensitive Input level control adjusted too high Re-adjust the input level (refer to page 8) Distorted sound Input level control adjusted too high Re-adjust the input level (refer to page 8) Blows fuse( s) at amp Power wires connected backwards Reconnect power wires properly Internal problem with amp Take unit for service Engine noise / Alternator whine Ground loop(s) Use good quality shielded RCA cables Faulty ground at amp Re- ground amp to clean bare metal chassis Faulty ground at head unit Re- ground head unit to clean bare metal chassis Inductive coupling Re- route RCA and/or speaker wires away from factory harnesses Input level on amp set too high Re-adjust input level (refer to page 8) Thermal protection activated Amplifier driving 2 ohm load for long durations If the amplifier “thermals” frequently while driving subwoofers, install fan to keep amp cool. Short circuit protection activated Blown speakers Check all speakers Speaker wire(s) shorting to ground Check for faulty wiring Defective crossover Faulty passive crossover Low impedance protection activated Amp connected to improper load Check speaker connections Amp will not drive a 1 ohm mono load, 2 ohm minimum in mono configuration Verify that speakers are connected properly Speakers defective/ blown Check speakers Faulty passive crossovers Check crossovers Poor bass response Speakers out of phase Check speaker polarity; reverse the connection to one speaker only if two subwoofers are connected to the amplifier. NOTE: If the protection light is activated with no speakers connected to the amplifier, and all the power connections are correct, this would indicate an internal problem with the amplifier. 13 PowerPlus Amplifiers CEA Power Output RMS Power Output @ 1% THD+N, 14.4VDC PowerPlus 420 Power Output: 65 watts RMS X 2 channels into 4-ohms @ < 1% THD+ N Signal to Noise Ratio: 100dBA below reference (Reference: 1 watt, 4-ohms) Additional Power Output: 90 watts RMS X 2 channels into 2-ohms @ < 1% THD+ N 170 watts RMS X 1 channels (Bridged Mono) into 4- ohms @ < 1% THD+ N Frequency Response: 10Hz to 60 kHz, -3dB ( Reference: 1 watt) Dimensions: L10.5" x H2.5" x W11.75" PowerPlus 840 Power Output: 70 watts RMS X 4 channels into 4-ohms @ < 1% THD+ N Signal to Noise Ratio: 100dBA below reference (Reference: 1 watt, 4-ohms) Additional Power Output: 100 watts RMS X 4 channels into 2-ohms @ < 1% THD+ N 175 watts RMS X 2 channels (Bridged Stereo) into 4- ohms @ < 1% THD+ N Frequency Response: 10Hz to 60 kHz, -3dB ( Reference: 1 watt) Dimensions: L14" x H2.5" x W11.75" PowerPlus 900 Power Output: 260 watts RMS X 1 channels into 4-ohms @ < 1% THD+ N Signal to Noise Ratio: 100dBA below reference (Reference: 1 watt, 4-ohms) Additional Power Output: 430 watts RMS X 1 channels into 2-ohms @ < 1% THD+ N Frequency Response: 10Hz to 240Hz, - 3dB (Reference: 1 watt) Dimensions: L17.25" x H2.5" x W11.75" PowerPlus 1150 Power Output: 330 watts RMS X 1 channels into 4-ohms @ < 1% THD+ N Signal to Noise Ratio: 100dBA below reference (Reference: 1 watt, 4-ohms) Additional Power Output: 550 watts RMS X 1 channels into 2-ohms @ < 1% THD+ N Frequency Response: 10Hz to 240Hz, - 3dB (Reference: 1 watt) Dimensions: L19" x H2.5" x W11.75" PowerPlus 1302 Power Output: 175 watts RMS X 2 channels into 4- ohms @ < 1% THD+ N Signal to Noise Ratio: 100dBA below reference (Reference: 1 watt, 4- ohms) Additional Power Output: 280 watts RMS X 2 channels into 2- ohms @ < 1% THD+ N 570 watts RMS X 1 channels ( Bridged Mono) into 4-ohms @ < 1% THD+ N Frequency Response: 10Hz to 60 kHz, - 3dB (Reference: 1 watt) Dimensions: L15.5" x 2.5" x 11.75" PowerPlus 1304 Power Output: 117 watts RMS X 4 channels into 4- ohms @ < 1% THD+ N Signal to Noise Ratio: 100dBA below reference (Reference: 1 watt, 4- ohms) Additional Power Output: 145 watts RMS X 4 channels into 2- ohms @ < 1% THD+ N 290 watts RMS X 2 channels ( Bridged Stereo) into 4-ohms @ < 1% THD+ N Frequency Response: 10Hz to 60 kHz, - 3dB (Reference: 1 watt) Dimensions: L15.5" x 2.5" x 11.75" Audiovox...
