First, ensure you have a solid ground connection. Next, check that the Remote Input (Turn-On) receives at least 3VDC. Confirm the (+) terminal has battery power of at least 12V. Inspect all fuses and replace any that are faulty. Finally, verify that the Protection LED is not illuminated; if it is, briefly turn off the amplifier before turning it back on.
