Good entry level sub

Nothing crazy but a good little sub. Easily compares to subs twice it’s cost.

12 inches

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.

1 2 3

Just 1 d2 wired up to 4 ohm rocks the block! Thank yall for helping me disturn the peace!

Outstanding

Just 1 on a 2500d power acoustic shakes the car and everything around it wired to a 4 ohm. Thank y'all over there at CT Sounds.

Great sound

This sub is a great sounding, however it doesn’t like a little extra power. I had this BioV2 in a 1.8cu ported enclosure on a Zapco 500rms and she would get smelly after pushing it for about 15 min. So I went ahead and just bought the Tropo. Can’t wait to hear it!

Crystal clear

The sound is amazing. The woven design, and the over all construction are very clean and aesthetically pleasing. I hate that the door speakers are covered up. I will def be adding this same set to the rear of the vehicle as well.

The product itself I'm happy with but I gave it 1 out of 5 stars because it took 3 months for 5 months for me to receive them
