Your cart is empty.Small enclosure, impressive bass When space inside your vehicle is limited, it can be difficult to find room for a subwoofer. MTX has solved this problem by creating a shallow-mount powered sub that fits in cramped confines to give you impressive bass without taking up a whole lot of space. So easy to fit MTX designed their TN8MS powered subwoofer to deliver high-quality bass response in an enclosure small enough to fit your vehicle's nooks and crannies. At only 3" high, this sub will fit under most seats and behind many truck seats. With a built-in amp that delivers 135 watts RMS to the low-profile 8" sub, you'll get the rich, full bass you need in a simple, easy-to-fit package. Tune it to your tastes You'll also get a full control set to tune your low end to your music and your tastes. A variable low-pass crossover lets you set the frequency anywhere from 50 Hz to 150 Hz so you can adjust the sound to best complement your speakers. The bass boost control gives you up to +12 dB of boost at 45 Hz, and the phase switch allows additional adjustment to dial in your system. A wired remote control connects to the sub via a 3.5mm cable, letting you adjust the bass response from the driver's seat. Secure and connected The TN8MS features speaker-level and line-level inputs so you can run the sub directly from your car stereo, or get a signal from your speaker wiring. The high-density aluminum enclosure keeps the sub and amp safe from thumps and bumps, and the metal grille protects the speaker. When you need lots of boom but only have a little room, the TN8MS gives you the sound you want in a compact package with easy installation and great sound.

Excellent fit and finish. Installation was a breeze using my factory radio. Sound is great and an awesome value.

I like these so much i have one in both my trucks. Easy to hook up and fit under or behind the seat. Fills in bass great. An absolute must in newer cars that you can’t easily replace the radio.

Bought this to put in my Avalanche last year as I wanted something compact that would fit under the back seat. I'm older now with kids, so I don't need two 12's and two 15's anymore just wanted something to add some low bass and compliment the upgraded head unit and door speakers. I chose MTX because I trusted their quality from many years of previous experience. I will say the unit was easy to install and gave me what I was looking for. Initially, I was impressed with the sound and happy with my purchase. That quickly took a turn. The first unit failed in less than a month. I returned it through Amazon. The return went great, Amazon stands by their return policy. Received the second and it was inoperable right out of the box. Returned it immediately. Received third unit. Hooked it up and was happy again for 10 months. It has now failed and I have returned it directly to MTX. All 3 failed units had the same issue. The unit will power up and show that it is ready to play but their will be no sound from sub, or it will rattle as if the sub is blown producing no bass. I have given each unit a break-in period as recommended and never had any of them above 75% gain. I have much experience installing and adjusting systems, and never pushed these units at all, I'm not looking for super bass, just a balanced system. I am ultimately disappointed in the quality of this unit and wish I could just get my money back to purchase a better quality sub.

Installed it in my 1995 Toyota Tacoma standard cab. Fit perfectly under passenger seat. The sound is awesome for me. This will not win sound competitions, but it gives a good amount of bass. I wish I would have tried this sooner.

I purchased the unit for my son’s 2010 Jeep Wrangler. We installed an after market Boss radio with apple car play and upgraded the 4 stock speakers with the Mopar kickers direct fit but the bass was lacking. This unit was perfect to finish everything off. We mounted it to the rear swing gate and after playing with the settings on the speaker/amp and radio and dampening vibrations, it sounds great and really fills up the Jeep with the perfect amount of loud bass without irritating the neighbors.

In my late teens and early twenties, I would have laughed at this option. The last setup I had was a single 12 JL W7 with JL 500/1 and a pair of bass shakers under the seats. This little thing definitely won't make your heart skip a beat, nor will it blow your eardrums. But after 20 years of 100% stock equipment, and aging ears from working in a manufacturing environment, this little 8" sub puts out a nice little bump. Complimenting my stock speakers. Will it get every bass note? Absolutely not, but it isn't a competition system either so take it with grain of salt..... Bottom line, if you just want a little better sound in your car, this is a nice addition for only $200. I was fortunate enough the previous owner of my car ran power and RCA, so my "install" took all of 15 minutes. Installed in 2016 VW Passat in the trunk affixed to back of passenger side fold down seat.

I'm a otr truck driver. Came home and it was easy to install as noted, and it worked OK for a couple days. I went back otr and came back now it won't do anything.(Nobody uses while I'm gone.) Green Light is on but as soon as volume is turned up at all the red light comes on. I think it could be a good product for the price..maybe mine was just defective. Being that I am over the road working, I missed the cut off period for returning. Liked the sound just wish I could have enjoyed longer.

This powered subwoofer fits perfect behind my f150 rear seat and adds all the low end bass the stock audio system is lacking. I’m currently running it at 50% gain and it sounds great.
