2020 Challenger RT

All - I saw a review on a bunch of sites by one guy with a Challenger who went with CT Sounds… he said they are his favorite speakers after trying a bunch of brands. I’m in the same boat. I’ve tried a bunch of brands, spent a bunch of money, and it was just okay. I gambled with CT Sounds and couldn’t be happier!! I spent a quarter the cost and got better sound. I’m running a CT-LC2, CT400.1, CT150.4, Tropo Loaded 8”, 2 sets of Meso 3-ways, and a shitty off brand 3.5” since CT Sounds doesn’t make a 3.5”. I haven’t installed the Meso 3-ways in the doors yet but the rest is in and I’m blown away! This isn’t some BS hype cause I got free shit.. No straight up there shit hits hard and loud. I haven’t even turned it all the way up. There’s still 65% left. I cruise with the windows down at 70 mph and it’s loud, crisp, and sounds amazing. It’s way more than I can say for those other brands! I don’t even have it tuned yet. Out of the box hands down the best you can get for your dollar. I can’t say enough. To top it off the customer service is the best! I through up some pictures. If you have questions about my install, [****]. If you have product questions [****], there customer service is the shit!

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
