What to do if my Phoenix Gold Z Series Subwoofer amplifier will not power up?

If your Phoenix Gold Subwoofer amplifier isn't powering on, start by ensuring you have a solid ground connection and that the Remote Input (Turn-On) receives at least 5VDC. Verify battery power is present at the (+) terminal, with a minimum of 12V. Inspect all fuses and replace any that are blown. Also, check if the Protection LED is lit. If the Protection LED is glowing red, try turning the amplifier off briefly, then turn it back on.
