Why is the protection LED on my Sound Magus ET150.4?
The protection LED might be on due to short circuits on the speaker leads, so check for any shorts. Also, ensure the speaker load isn't beyond the minimum. Try removing the speaker lead and resetting the amplifier. If the LED remains on, the amplifier may be faulty and require servicing.
What to do if my Sound Magus ET150.4 will not power up?
First, ensure you have a solid ground connection. Next, verify battery power is reaching the (+) terminal. After that, inspect all fuses and replace any that are blown. Finally, confirm that the Protection LED is not lit.
Why is my Sound Magus ET150.4 getting very hot?
Ensure that the minimum load impedance for your amplifier model is correct. Also, make sure there's good air circulation around the amplifier. In some cases, you might need to add an external cooling fan.
Why is there distorted sound coming from my Sound Magus ET150.4 Car Amplifier?
Check 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 properly configured. Finally, inspect the speaker leads for any short circuits.
What to do if there is no output from my Sound Magus ET150.4 Car Amplifier?
Check that the RCA audio cables are correctly plugged into the proper inputs. Inspect all speaker wiring. Also, check both the headunit output and the amplifier level setting.
How to fix low output on Sound Magus ET150.4 Car Amplifier?
Try resetting the level control. Also, check the crossover control settings.
