Why is my amplifier not working?
If the Amp Doesn’t Power On at All To turn on, the amp needs power at both the remote and power wires, in addition to a good ground. If the remote turn-on wire doesn’t have power, your amp won’t turn on. If it doesn’t, check for any inline fuses and verify that the wire isn’t loose, corroded, or shorted out somewhere.
Can a blown amplifier be repaired?

What is the rule of thumb for MTX amplifiers?
The rule of thumb is to match the amplifier RMS power output, (also known as continuous power) to the subwoofer with comparable RMS power handling capability. When using multiple subwoofers, you must total the power handling for all the subs. That number should closely match the amplifier dynamic power.
