  • this. thing. SLAMS.
Size: 12" Style: Dual 4 Ohm
this thing slams. i have the voice coils running in parallel, so 2 ohm load on the amp. in a ported box. running about 300W, and the people next to me at stop lights hate me, because it's shaking their mirrors. quite happy with this purchase.

  • Amazing Subwoofer Upgrade for My BMW X6!
Size: 10" Style: Dual 4 Ohm
The CT Sounds Hydro 10” Dual 4-Ohm Subwoofer fit perfectly in my 2012 BMW X6 with its shallow mount design. Even though it’s a shallow sub, the bass it produces is incredibly deep and powerful. Installation was smooth, and the dual 4-ohm setup gave me flexibility for wiring to my amp. The sound quality is very clean, with tight bass hits that enhance all types of music. I’m impressed by how much punch it delivers without taking up too much space. The subwoofer feels well-built and handles high power without any distortion. Highly recommend it to anyone looking for a big sound in a tight space! ... show more

  • Great little subwoofer
Size: 8" Style: Dual 2 Ohm
Sounds ok installed in the same place as a stock subwoofer in 2014 jeep grand cherokee. have a rockford fosgate r2-1200x hooked to it turned down though it holds the power just fine. plastic box stock is not the best though.

  • Great build quality and sound!
Size: 10" Style: Dual 2 Ohm
Great build quality and sound for a shallow mount 10in. I’m sure this thing really has a lot of potential in the right box but I had to use the smallest box I could find since I installed this in a Kenworth dump truck. I’ve owned multiple subs and never noticed a difference after a break in but this thing continues to get better with time. I listen to it pounding all day 10-12hrs a day powered by a ct sounds 400.1d compact amp with no issues. Will definitely buy agin for future projects. ... show more

  • CT Sounds Rocks
Size: 10" Style: Dual 2 Ohm
These 10s hit very hard combined with CT sounds 1500 watt amp...after the break-in they seem to push harder and harder...i would give 6 stars if I could
