Installation Tips:

1. Make sure to use the correct gauge wiring, for the CT-80.4AB we suggest using 4GA power wire, anything smaller is never recommended for this amplifier. 

2. Make sure to properly ground your amplifier. We recommending grounding to the frame of your car. Make sure to clean the surface well, sand down the surface removing any paint, dirt, rust, etc.. so the connection is as strong as possible. We recommend using a bolt (do not use screws). Do not ground the amplifier to a seat bolt or any existing bolt on your vehicle (this a really a bad idea).

3. Tune your amplifier with a DD-1 or O-Scope, make sure it is not clipping. Clipping is the leading cause of subwoofer deaths.

4. Do not mount your amplifier to your subwoofer box. Mount your amplifier away from the subwoofer enclosure in a secure location. Vibration is one of the leading causes of amplifiers deaths. 

Note: If your amplifier is getting hot and/or shutting off it is likely because you did not follow the above. A poor ground, a loose connection, using too small of wire, or not using OFC wiring is the main reason this would happen.
