If your Jensen Car Amplifier is producing distorted sound, the input level control might be set too high. Try readjusting the input level.
What to do if my Jensen PS1220M Car Amplifier keeps blowing fuses?
If your Jensen Car Amplifier blows fuses, it could be due to power wires connected backwards. Ensure the power wires are correctly connected. Alternatively, there might be an internal problem with the amplifier, requiring professional service.
How to fix a Jensen Car Amplifier that does not turn on?
If your Jensen Car Amplifier isn't turning on, it could be due to several reasons. First, check the fuse(s) for the +12V terminal. Next, verify the head unit fuse(s) and wiring for the REM terminal. Also, inspect the main fuse at the battery and the fuse at the amplifier; replace them if blown, identifying the cause of failure. Lastly, ensure the main power ground is securely connected to a bare metal chassis.
How to eliminate engine noise in Jensen PS1220M Car Amplifier?
If you are experiencing engine noise or alternator whine with your Jensen Car Amplifier, it could be due to several factors. Try using good quality shielded RCA cables to address potential ground loops. Ensure the amplifier and head unit are grounded to a clean, bare metal chassis. Reroute RCA and speaker wires away from factory harnesses to avoid inductive coupling. Lastly, check if the input level on the amplifier is set too high and readjust it if necessary.
Why is short circuit protection activated on my Jensen PS1220M Car Amplifier?
If the short circuit protection is activated on your Jensen Car Amplifier, check all speakers. Also, inspect the speaker wires for any shorts to ground and check for a defective crossover.
What causes low impedance protection to activate on Jensen PS1220M?
If the low impedance protection is activated on your Jensen Car Amplifier, check the speaker connections to ensure the amp is connected to a proper load. Verify that the speakers are connected correctly, noting that the amplifier cannot drive a 1 ohm mono load (2 ohm minimum in mono configuration). Also, check the speakers themselves for defects and inspect the crossovers.
Why is the volume control too sensitive on my Jensen Car Amplifier?
If the volume control on your Jensen Car Amplifier is too sensitive, the input level control may be adjusted too high. Try readjusting the input level.
