Why EXCURSION Car Amplifier protection LED comes on?
The protection LED might activate due to short circuits in the speaker leads or if the speaker load exceeds the minimum specified. Inspect the speaker leads for shorts and ensure the speaker load is within the amplifier's limits. You can also try removing the speaker lead and resetting the amplifier. If the protection LED remains on, the amplifier may be faulty and require servicing.
Why EXCURSION Car Amplifier will not power up?
If your EXCURSION Car Amplifier isn't powering on, verify you have a solid ground connection and that the (+) terminal is receiving battery power. Also, inspect all fuses and replace any that are blown. Ensure the Protection LED is not lit.
What to do if my EXCURSION Car Amplifier gets very hot?
If your EXCURSION Car Amplifier is overheating, verify that the minimum load impedance for your amplifier model is correct. Ensure there is adequate air circulation around the amplifier. If necessary, consider adding an external cooling fan to improve ventilation.
How to fix distorted sound in EXCURSION Car Amplifier?
To address distorted sound in your EXCURSION Car Amplifier, begin by checking that the input level control is appropriately set to match the head unit's signal level, keeping it as low as possible. Also, verify that all crossover frequencies are correctly configured and inspect the speaker leads for any short circuits.
Why is there no output from my EXCURSION Car Amplifier?
If you're getting no output from your EXCURSION Car Amplifier, first check that the RCA audio cables are correctly plugged into the appropriate inputs. Next, inspect all speaker wiring. Finally, check the head unit output and the amplifier level settings.
How to reduce high hiss in EXCURSION Car Amplifier speakers?
To reduce high hiss in your EXCURSION Car Amplifier speakers, check that the RCA cable is not shorted to the power ground at the amplifier side. Also, check the amplifier grounding.
