Customer service

Purchased ct400 , received in a few days. Unfortunately amp would prematurely go into protect mode. Worked with customer service trouble shooting via emails, returned. CT verified issues and replaced with upgrade. I was please to see a company truly stand by its products. My only issue is lack of live phone customer support. I would definitely recommend CT Sounds

Amazing!

What a solid little amp. I have it wired down to 1 ohm paired to 2 strato 6.5’s and they pound! For the size along with several YouTube reviews showing that this puts out almost 500 watts at 1ohm. Ran it hard right out of the gate after setting the gains and it makes those little subs come alive. Very clean sound and solid bass. My system has never sounded better

Ct400

I’m just a grandpa that likes to jam. The CT 400 fits the bill.I don’t need a lot of power. If I can catch a 4 channel on sale I’m probably get it

Great little amp!

Just installed this one on a JBL Club 10" in an explorer and she is way stronger than the ratings. Great build quality and sounds awesome as well. The small footprint makes it very versitle as well. Great job CT Sounds.
