If you own or are thinking of buying any large CT chassis amps, please read this post and watch the short video I'm including here. I was a CT dealer for a long time but have dropped the line and this post will demonstrate but one of the myriad reasons why I no longer sell the brand.
To begin with, the amps I'm talking about are the 2.2K, 3K, 4K, 7K and while it's yet to be confirmed, the 125.4. The problem with these amplifiers is a conspicuous lack of any sort of vibration damping in the center of the rather wide PCB (board). The designer of these boards saw fit to design them with holes that are meant to have posts in them that house rubber or vinyl mounts that would secure the PCB and stop any vibration damage and, the boards are currently manufactured with those holes in place. However, none of these amps, up until the time I dropped the line, have them inside.
The result of this manufacturing omission is the genesis of much of the talk you've heard about CT amps being subject to going up in smoke at any time and that talk is not rumor or bashing, although it is often presented as such by people who do not actually know or understand the problem.
If you have one of these amps DO NOT install it inside the cabin of your vehicle, whether it's on an amp rack or not, because the vibrations from sound pressure will eventually cause the legs on at least one FET to break away and, of course, let the smoke out of it.
My experience has been with two 2200.1s and two 3000.1s, all of which have broken legs on FETs and one of which has been to repair twice for the same problem. The 2.2Ks were mounted on a sturdy amp rack in a trunk and they lasted about 10 months. Those were the longest lasting, btw. One of the 3Ks went up in smoke about 40 minutes after it was installed on an amp rack that was in front of a box and the other lasted six days on an amp rack that was mounted above the blow through opening in a truck. That amp was sent to repair (after CT refused to even give me an RA number for it) and was then put on an amp rack in front of a very sturdy single 18 box. Prior to the CT amp being installed there had been an Audiopipe 3K in that location for about four months and after it smoked in ~8 days, we installed a Skar Audio 4500.1 and that amp has been playing for about two months now.
I've also had conversations with a handful of other former CT dealers, all of whom have experienced similar issues with these amplifiers.
Lastly, if you've had problems with these amps please contact me by phone or text at the number listed on my facebook page (facebook.com/audioanarchyllc) and send any photos you have as evidence of said problems.
Thanks!

Oh and, here's the video I mentioned....
