Troubleshooting

Problem

Possible Cause

Corrective Action

 

 

 

 

Amplifier does not operate

No power to +12V terminal

Repair wire or connections

(power LED not on) when

 

 

 

 

 

 

vehicle and radio are on

No power to remote wire with radio on

Check connections to radio with test light

 

 

 

 

Fuse blown

Check fuse

 

 

 

Radio volume needs to be

Input level control (gain control)

Adjust input level control (gain control)

turned up too high for amp

adjusted too low

 

 

to work

 

 

 

 

 

 

Radio volume is too sensitive

Input level control adjusted too high

Adjust input level control to lower setting

 

 

 

Sound from only one speaker

Defective speaker

Replace speaker

 

 

 

 

 

Poor connections to speaker (wire)

Check connections

 

 

 

 

 

Speaker wires shorting together

Separate speaker wires and insulate

 

 

 

 

 

RCA input cable defective

Replace cable

 

 

 

 

Sound distorted

Input level control adjusted too high

Adjust input level control

 

 

 

 

Blows fuses

Speaker wires shorting together

Separate speaker wires and insulate

 

 

 

 

 

Power wires hooked up incorrectly

Check power wire connections

 

 

 

 

 

Speakers blown or defective

Check speakers

 

 

 

 

Alternator whine in outputs

Radio has poor noise immunity

Disconnect audio inputs to amplifier – if noise disappears

(vehicle ignition noise)

 

then the radio is at fault

 

 

 

 

 

Improper ground connections

Make sure radio and amplifier are grounded to the same point

 

 

 

 

Loud pop in speakers when

Remote wire (blue) not properly

Refer to page 4 for proper installation. If radio does not have a

power is turned on or off

connected

power antenna lead and you have connected the remote lead to

 

 

an ignition source then you may get a “pop” in your speakers.

 

 

This is not uncommon. You may have to put a switch in line with

 

 

the remote lead to turn the amp on/off manually.

 

 

 

 

Protect light comes on/

Amp is in thermal protection

Let amp cool down before attempting to turn back on (some

amplifier shuts down

 

installations may require a fan to keep the amp cool, especially if

 

 

you are driving subwoofers with the amp)

 

 

 

 

 

Faulty speaker connection and/or

Check speakers and/or crossovers for loose or bad connections

 

crossover

 

 

 

 

 

 

 

Low battery voltage

Make sure you are getting between 10.8-15.6 volts to the

 

 

amplifier with a digital multimeter measured at the amplifier

 

 

 

 

 

Speaker impedance less than 2 ohms

If you are using 4 ohm speakers you cannot have more than two

 

per channel

speakers wired in parallel per channel Amp will not operate

 

 

into 2 ohms bridged

 

 

 

 

No output on channels

Speaker wires not connected to

Refer to pages 5, 6 and 7 for proper installation

 

speakers properly

 

 

 

Input hooked up incorrectly
