If your Jensen Car Amplifier isn't turning on, it could be due to several reasons: * There's no power to the +12V terminal. In this case, you should repair the wire or connections. * There's no power to the remote wire when the radio is on. Check the connections to the radio with a test light. * The fuse is blown. You should check the fuse and replace it if necessary.
What to do if the protect light comes on and my Jensen Car Amplifier shuts down?
If the protect light is on and your Jensen Car Amplifier shuts down, here's what you can check: 1. The amplifier might be in thermal protection. Let it cool down before trying to turn it back on. Consider adding a fan to keep it cool, especially if you're using subwoofers. 2. There might be a faulty speaker connection or crossover. Inspect the speakers and crossovers for loose or bad connections. 3. The battery voltage might be low. Ensure you're getting between 10.8-15.6 volts to the amplifier, measured with a digital multimeter at the amplifier. 4. The speaker impedance might be less than 2 ohms per channel. If using 4 ohm speakers, ensure no more than two are wired in parallel per channel. The amplifier won't operate into 2 ohms bridged.
How to eliminate engine noise in Jensen A400HLX?
To eliminate engine noise (ignition noise/static or alternator whine) in your Jensen Car Amplifier, try these solutions: * Reroute the RCA cables away from the main power wires. * Reroute RCA cable. * Ensure the amplifier is grounded to a clean, solid part of the chassis/frame.
Why does my Jensen A400HLX Car Amplifier keep blowing fuses?
If your Jensen Car Amplifier keeps blowing fuses, it could be due to: * Power wires hooked up incorrectly, so check the power wire connections. * Speakers that are blown or defective, so check the speakers.
What to do if sound coming from only one speaker with Jensen A400HLX?
If you're only getting sound from one speaker with your Jensen Car Amplifier, consider the following: * The speaker may be defective, replace the speaker. * There may be poor connections to the speaker wire, check the connections. * The RCA input cable may be defective, replace the cable. * The input level control may be adjusted too high, adjust the input level control.
Why is my Jensen A400HLX Car Amplifier's radio volume too sensitive?
If your Jensen Car Amplifier's radio volume is too sensitive, it's likely because the input level control is adjusted too high. Adjust the input level control to a lower setting.
Why does the radio volume need to be turned up too high for my Jensen A400HLX Car Amplifier to work?
If the radio volume needs to be turned up too high for your Jensen Car Amplifier to work, it's likely that the input level control is adjusted too low. Adjust the input level control to resolve this.
