CT Sounds 8 inch subwoofer dvc 2 edition. Easy to setup to 4, 2 or 1 ohm. Currently running mine on a mono block kicker amp at 2 ohm and it sounds fantastic. It definitely can take more power. Ite sub size is accurate, got mine in a NVX sealed enclosure. Seems very durable and well made. If you are on a budget or just want to try something different, definitely give the CT Sounds Bio a shot. ... show more

    • Quality products for your car stereo
Size: 8" Style: Dual 2 Ohm
I’ve been in the sound business for a large portion of my life. Mostly live sound. I bought this to replace the cheap sub that came stock in my truck. From the build to the quality coming out of this little sub. Truly well designed and built sub. You feel and see the quality the second you open the box. I will be proudly rocking the ct sticker that came with my speaker on my truck. It’s at the same level as a kicker in a comparable output for a fraction of the price . ... show more

    • Substantial improvement
Size: 8" Style: Dual 2 Ohm
Replaced the JBL sub from a Tacoma with this. Sounds great with the factory amp. Well worth the money. Mounting holes didn’t line up but just drilled new ones and works like a champ. Also found pigtail connectors on Amazon to plug into the factory wires inside the in closure.

Ordered 3 of the 8" Dual 2-Ohm Subs for some bump in the ride. First one showed up earlier then expected, upon inspecting the subwoofer i noticed some damage to the side of the magnet which didnt look right to me. I did order all 3 brand new so just wondering if anyone else had the same issue but figured I'd just contact ct sounds and see what they think. Got a reply after sending pictures of the damaged area on the magnet, after reviewing they stated does not affect performance of the sub. So im confused cause im not trying to be picky but I dont like something that looks damage or used if I paid for a new product. Smh well contacted Amazon for a replacement and now I have to wait even longer. Mind you I never tested the sub or used it. Just opened the package to inspect. After researching and looking for decent subs, ct sounds looked like a winner but now I dont think so. Sorry for the rant but look somewhere else for 8" subs! P.S. still waiting on the other 2 that should of been shipped all together.. smh 2X ... show more
