    • Powerful Bass in a Slim Design – Great Fit for Any Car
his FOLTUSYMY 10-inch slim subwoofer delivers impressive bass for its size. The sound is deep, clean, and powerful without distortion, even at higher volumes. It fits perfectly in tight spaces, making it ideal for smaller cars or under-seat setups. Installation was simple and the build quality feels solid. Great performance for the price—highly recommended. ... show more

    • Overall can’t complain.
I wanted to give this product a couple months before I wrote a review. But I bought this product back in march, I did have trouble hooking it up but it was on the head unit side that was causing me the issue not this itself. Once I figured it out it was easy smooth sailing. Overall for the price you pay for it and given how “small” it is, I think it hits and sounds really good. The quality of the build on it seems half decent it is pretty heavy and solid. It alittle tight underneath the seat but other than that it’s perfect. Now the volume control button is terrible, it’s almost like they gave up right at the end with it to push the product out. But other than that. I’d recommend it if you’re looking for a something and on a budget. ... show more

    • Good buy so far so good
The media could not be loaded. Close to 5 stars the wires were cut just right for my car and the speaker comes with a full install kit. Still have to play with it a little more but a fairly quick install on an after market head unit. If hooking to factory unit a voltage tester to hook up the line out converter will save you some headache trying to figure which wire to tap into with the line out converter. I’m happy with this purchase not monster bass but sounds more like a movie theater bass. Also make sure your ground area doesn’t have any pant where you screw the ground I hooked mine to the screw on my back seat. ... show more

    • I love it!
I put this in my 1979 Corvette and I loved what it does. It fills in the missing low frequencies and makes the car fun to drive. I love it, I have been building car audio systems for 45 years and this was an easy way to add bass without a huge box. Tuning is critical but it works very well.

    • Would not recommend this product!!!
I bought this in August of 2024, I have not been able to get it to work since I bought it. At first, I thought I had my speaker wires wrong. So, I tried the 2 front speakers, nothing after a second of powering on, the green LED turns red. So, next, I bought a new line output converter, and it's the same thing. RED LED. Finally, I completely disassembled the rear doors and connected the speaker wires directly to the rear speaker wires, but there was still nothing. This is crazy, I am an engineer for Mitsubishi, and I travel for a living, so I only get a few days a month to work on this, and I give up. Regretting this purchase! Also, I have a degree in electrical engineering, so if I can't get it, good luck to everyone else. ... show more

    • Decent little woofer that comes with all you need
Review Image by Kimberly R. Urban Kimberly R. Urban
The media could not be loaded. This is a decent little subwoofer. It is priced affordably, and comes with a wiring kit that provides all you should need to install it. It is designed to put under a car seat, but the spider casing is pretty cool-looking and it is back-lit blue, so it will look good wherever you decide to install it. It has decent sound quality with acceptable base, considering its small amp. It was easy to install and definitely improves the audio experience in my FiestaST, which has absolutely garbage stock sound lol. ... show more
