Installation Tips:

1. Make sure to use the correct gauge wiring, for the CT-80.4D 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.

Amazing !!

I have one of these little guys hooked up with 4g OFC coming off the distro block with 1/0 OFC coming off the battery to the block, and its amazing. I have 2 Meso 6.5 PA's and 2 Meso 6x9 Coaxial's hooked up to it, and they sound great ! Tuned with a DD1, no distortion. Takes all the power it can and still doesn't get hot. Defintely recommend it to anyone who is looking to hook up some good vocals.

Amp review

Sorry to say but I've beeen acquiring all my parts to a project I'm working on and haven't installed them yet . Lookinh forward to when I finally do though

CT Sounds is the way to go 💪💪

Love my CT 80.4 crisp and clean output and this lil amp packs a mean punch for the size

To start with the amp was packaged extremely well there was an outer box that opened up to another box that was surrounded by air bubble packing and inside that was the actual box that the amp was in and when I opened that box the amp was tightly fitted in foam I was very pleased and impressed by the packaging alone as I have recently had to send a few things back that were damaged during shipping because the items were just tossed into a box and shipped. When I got the amp out it has a quality look and feel to it. For no bigger than what it is it has some weight to it. So again I was impressed but then I got it wired up and mounted to my amp rack and I was blown away. I bought this run a couple sets of tweeters and when I heard what it was doing I swapped my 200watt rms ×4 midrange amp to tweeters and hooked up the CT-80.4d to my midrange and midbass speakers at 2 ohms and it sounded so good that is how I left it. My system had a huge improvement in overall sound quality from adding this little amp it is amazing and judging by this amp purchase I will be using CT Sounds for any future amplifier needs and highly recommend it to anyone looking for clean powerful mids or highs. I liked this amp so well that I have already ordered a set of CT Sounds 6.5" Meso 400 watt rms subwoofers because they were on a really good offer. Not sure what I'm going to do with them yet but I will think of something

Great amp!

Very happy with this amp. Been using it for around 5 days. It is loud and crystal clear and barely gets warm after about 20 mins of full tilt play. Also has a nice small foot print. Would recommend!
