Check for blown fuses and if necessary, replace them. Add the audio cables to the amplifier first and make sure the cables are securely connected. Then test the amplifier to make sure there are no issues. Add the speaker wires one at a time to make sure the connections are accurate and secure.
Why is my amp getting power but not my subs?
Commonly, a blown subwoofer, issues with the connection and wiring, volume and other settings, input problems, short circuits and issues with the speaker can be some potential reasons behind a subwoofer not working even if the amp has power.
How can you tell if your amp is blown?
How do you diagnose an amplifier? Test the sound by unplugging the sound cables or colored RCA wires. Hissing and crackling are often easy to fix by rearranging the wires or getting complimentary speakers. If the noise doesn’t stop, then you probably have a faulty amp to replace.

Why did my amp just stop working?
If the ground connection is poor or isn’t connected at all, the amp might fail to turn on or not work very well. If the amp has good power and ground, the remote wire has voltage when the head unit is turned on, and no fuses are blown, then you’re probably dealing with a busted amplifier.
Will amp turn on if fuse is blown?

Link the amplifier with a mic.
Check all accessible fuses and use one fuse in the amplifier.
What happens when a fuse blows in an amp?
The immediate symptom is the same as for an overload—the metal ribbon inside the fuse burns through and all lights and fixtures along the circuit go dead. But in the case of a short circuit, merely replacing the fuse will likely cause the new one to blow immediately—unless the short circuit has been fixed.
What happens if your amp turns red?
The POWER/PROTECT light will change from green to red under the following circumstances: When the car amplifier is overheated (thermal overload). A speaker wire has short-circuited. DC current is generated.

What can damage an amp?
The two most likely possibilities for damage are: – Connecting the speakers incorrectly, putting a heavy load on the amplifier and overheating it. Usually one channel goes before the other. – Cranking up the volume on the amp and ruining loudspeaker driver(s).
