Powerful Amp!

I have this paired up to a set of Meso 6.5 components and Coaxials in my CRV. I know an A/B amp is supposed to produce cleaner sound but this little guy does not disappoint! I can crank it up to almost clipping without any distortion! Was amazed at how much my system came alive with these amps. So much better than the old AB I was running before! These amps are tiny for their output and videos have shown them to put out more than their ratings so I have had no issues.

150.4 4 channel amplifier

Small foot print easy to install plays my mids and highs great would buy another one in the future

Still haven’t had time to install it. When I install it,I will review it. I’m in no rush to do so at this time stay really busy.

John Brown
CT Sounds is such a value

I needed an amp for mods and highs that didn't break the bank but still was bright, and loud. Paired with Meso 2 and 3 way components the CT150.4D is ridiculous. It may be the best value in 4 channel amps out there!
