CT Sounds Bio 10” 800-Watt Dual 4-Ohm Car Subwoofer

Solid subwoofer for the value so far. Does well as a replacement in a Polk box with amplifier.

Sub works awesome, have it hooked up to a 3500 watt amp and it sounds great, hits the lows better than highs but overall a solid subwoofer.

One of the best speakers I ever bought Baseline on this hit hard and I got it for my Kei van and if you guys know about those vans or trucks there's not a lot of room because of how small they are so I have a hundred Watt amp and let me say when this thing plays you would think that it was playing on a stronger amp and the way it sounded so clean and so pristine that people stop me and ask me what kind of speakers you got in there and I show them they're like I don't even know this brand but it sounds good I'm like yeah I would buy from them again love it

I wanted an affordable sub that I could make a 2 ohm overall load for a cheap Bluetooth boom box amp. I parallel wired the voice coils and let it rip. Does it rattle the windows out of the house? No. Does it handle all the limited amount of power I've thrown at it so far? Absolutely (supposedly 350 watts). If you're making a portable ghetto blaster and want a little bit of thump to it, this thing will work well. It takes some power to get it moving so don't have too high of expectations if you're giving it low wattage. Some of those amps don't seem to really drive the sub channel until like 1/2 power and up.

Very happy with speaker. Will buy another

This sub is good for the price. If you're good at tuning, and you have a bass knob then you can make this thing bump.

Sounds great and nice little punch to it, I have it in a 1 cubic ft ported box with a JL Audio JX200 and it works perfectly, i can smell the glue heating up but doesn’t have distortion, for its size and price this 8 inch is a real budget bang for your buck

I bought two CT Sounds Bio 10” 800-Watt Dual 4-Ohm subwoofers and paired them with a 2000-watt amp (about 1000W RMS) along with a SKAR SK2X10V enclosure. Right out of the gate, the setup was impressive. The sound is crisp, clean, and hits way harder than expected for 10s. Inside the cab, the bass is insanely strong—tight when it needs to be, but still able to shake the whole truck when the track calls for it. They don’t sound muddy or sloppy, even when pushed, which really surprised me for the price range. Paired with the right tuning, these subs really come alive. The enclosure helped a lot too, and together everything feels well-matched and balanced. For daily listening, they’re more than enough and still have headroom when you want to turn it up. Overall, I’m very happy with the setup—clean output, strong bass, and a setup that hits harder than you’d expect in the cab.

These 10 inch are amazing they hit hard very happy with them I do recommend these Woofers.
