Why does my Infinity Amplifier lack punch?
If your music lacks 'punch' when using the Infinity Amplifier, the speakers might not be connected properly. Check the speaker connections to ensure they have the correct polarity.
What to do if Infinity Amplifier has distorted audio and PROTECT LED flashes?
If your Infinity Amplifier is producing distorted audio and the PROTECT LED is flashing, it indicates a short circuit in the speaker or wire. To resolve this, remove the speaker leads one at a time to find the shorted speaker or wire, and then repair it.
What does it mean if PROTECT LED is on on my Infinity 7541A?
If the PROTECT LED is illuminated on your Infinity Amplifier, it means the amplifier is overheated. Ensure that the amplifier's cooling is not blocked at its mounting location. Also, verify that the speaker-system impedance is within the specified limits.
What to do if my Infinity 7541A Amplifier has no audio and PROTECT and POWER LEDs flash?
If your Infinity Amplifier has no audio and both the PROTECT and POWER LEDs are flashing, the voltage on the BATT+ connection is less than 9V. Check the vehicle's charging system to resolve this issue.
