Installation Tips:

1. Use pure OFC Copper Wiring. Make sure to use the correct gauge wiring, for the CT-1500.1D we suggest using 4GA power wire, anything smaller is not recommended for this amplifier. We do not recommend using CCA wiring. CCA wiring is cheap, it is made using primarily aluminum. The amplifier will perform less than optimal if you decide to use CCA wiring and may even shorten the life of the 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 amplifier 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.

This amp is a beast in a small footprint! Awesome power and sound and quality! Never had any issues with this amp! CT Sounds is great quality and I’ll be buying more soon!

At first look it doesn't look like this little amp can really push 1,500 watts, but just like a book, don't judge it by the looks. My CT1500.1 is ran on silver tinned 1/0 100% OFC wiring and takes every bit of power I send through it. I recommend this amp to anyone ! Put some anti-vibration rings between the bottom of the amp and where you're mounting it, and it'll live forever too. For those who don't know, this amp uses heating distribution, NOT fans so don't mount it directly to carpet or you'll get it hot. The vibe rings keep it high enough too that the amp can properly vent and run for hours.

Not hook up yet

Got the subwoofer in and boxes . Just taking my time hooking everything up right. By the looks of it its solid and have a good weight to it. All I'm waiting for is true gauge ofc 1 gauge wire for the amps.
