If you're experiencing alternator noise that varies with RPM in your PowerBass Amplifier, try the following: * Check for a damaged RCA cable. * Check the routing of the RCA cable. * Ensure the source unit has a good ground. * Check the amp gain setting; if it's set too high, turn it down.
What to do if Power LED is green but there is no output on PowerBass ASA 1500.1Dx?
If the power LED on your PowerBass Amplifier is green but there's no output, consider these steps: * Check the RCA connections. * Test the speaker outputs with a known good speaker. * Substitute a known good source unit. * Check for a signal on the RCA cable using a VOM in AC position.
How to troubleshoot Power LED not ON on PowerBass ASA 1500.1Dx?
To troubleshoot why the power LED is not on for your PowerBass Amplifier, use a Volt Ohm Meter (VOM) to check: * The +12 Volt power terminal (it should read +12 to +16VDC). * The remote turn-on terminal (it should read +12 to +16VDC). * The ground terminal.
