Installation Tips:

1. Make sure to use the correct gauge wiring, for the CT-700.1D we suggest using 4GA power wire, anything smaller is not 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.

Great amp pushes the sub very well only 1 12 does the job very well not even half way up!

CT Sounds Upgrade

I recently bought a small upgraded system from CT Sounds. Bio 6.5 coaxial speakers, 2 Tropo 8" subwoofers, and CT-700.1D. I am a person who does car audio instantly for others. I have over 35 years experience in car audio. CT Sounds is one of my favorite brands. I had been buying Skar Audio for people who were on a budget. Although I have no problem with Skar Audio, I would gladly pay CT Sounds a little bit more for their products. Fastest shipping I have ever had. The next build I will be doing in my wife's car and my truck will be CT Sounds Meso subwoofers. Thinking about 3 12s for me and 4 8s for my wife. I can't wait until I get time to make my own personal builds CT Sounds. This is a great company who take care of their customers. I would recommend CT Sounds to anyone who asked.
