Love it

Almost perfect.

I bought 2 12's. 4 door speakers. And an amp all from CT sounds. I'm extremely pleased with everything except one of the 12's is giving me issues when wiring the 2 voice coils together. Everything else is sounding great!! Recommending CT sounds to everyone that's looking. Especially all Texans. Hold it down homies.

Perfect ! Sounds amazing bassline hits at the right time.

Great sounding sub for the price.

Great sounding sub for a very good price. Sounds clean and hits all the lows.

Will get more

Got it , loved it, got stolen, someone else is loving it. 😩😭🤬

Absolutely crystal clear

These components are some of the best you can get for the money. At under $10 these are a steal. Every time someone gets in my car they are blown away by the clarity and output of these. I have them being powered by an American bass 4 channel putting out 100rms to each channel. These two sets of components get plenty loud and are perfect in the mids/highs to blend with subs.

super sound

First time trying these . going to addsome power to them and see how well they do ..Thanks CT

Size seems like they are a little smaller than the normal but great looking feels like a quality made shirt

Best Company!HANDS DOWN!

I am extremely happy with my purchase along with the entire process, and the speakers sound amazing! CT sounds is very quick to respond to questions! I will definitely place another order with CT sounds.
