MB Quart DS Inch Shallow Space Saving Slim Subwoofer Car Speakers with Dual Voice Coil for Vehicle Sounds Audio Systems, Black

Easy to install and performs well in my 2005 4 runner v-6. Fits very well and sounds good.One installation tip: several internet videos show how to install the subwoofer of a generation four (includes the 2005) 4 runner. The videos instruct the installer to dismantle MUCH of the trim on the floor, interior sidewall, and even the right rear seatbelt. Many screws, panels, yanking and pulling!One video suggests a much easier way to swap out the rear sidewallsubwoofer. I tried it, and it works like a CHARM! No screws, panels, carpet, or seatbelt to deal with.You simply cut out the grooved perimeter of the integral sidewall screen that guards the surface of the original subwoofer. Use a sharp, heavy duty utility knife and carefully work your knife around the outer groove of the screen. Take your time and don’t slip with the knife.With a few passes the entire screen will drop out of the rear sidewall. Trim up any ragged edges.The entire subwoofer can then be accessed easily. It will be staring you in the face.Carefully pull apart and unscrew the trim on the original subwoofer. Eventually, you will expose the six or so screws that hold the subwoofer in place. Unscrew the unit from its anchor points , pull it out gently and then disconnect the electrical connections. Note that the connections of the old subwoofer will not fit the unit I bought in this review.Most likely you will snip off the plastic fittings of the vehicle wiring, expose some bare wire and then connect the bare wire from the vehicle to the quick-connect fittings on the new subwoofer.Most likely you will have to drill a few new screw holes in the ring surrounding the new subwoofer to get a secure mount. This is easy to do.Connect all of the color coded wires in the correct terminals (See multiple videos on this; again, easy). Test to know if the subwoofer produces sound from your stereo.Once the unit is wired connected and screwed in place place a bead of clear silicone on the edge of the panel screen that you cut out and replace the screen in the sidewall. I let mine cure for 24 hours. If you’re a neat worker no one will ever notice (except for maybe your dog) that the screen had been cut.A fast worker can replace the subwoofer in probably 45 minutes of easy work. It took me about 1.5 hours, because I’m slow.Don’t be afraid to cut that screen panel. I learned this technique from a guy who posted his how-to video on the internet. His is a great solution to an otherwise significant PIA.

2002 Suburban factory sub upgrade. Perfect fit and great sound.

This thing sounds way better than the factory sub. I'm running it at 4ohms from the factory jbl amp in my 08 tundra and it sounds great! That being said, it's nowhere near the bass from a stand alone system, but it is plug and play and sounds really good.

For the price I doubt you can even match this sub. It’s not a sound quality sub. I’d used used JL audio, Sony, MTX, Polk, Audiobahn, and now MB Quart which used to be amazing in the 90’s. This sub isn’t “musical” not very tight, but that can definitely be at least partially my factory amp (2019 Golf R) causing that. With the recommended .65 cu ft box the sub favors 60-80Hz and basically falls on its face below 50Hz. I put it in a box I have that’s .81 cu ft and it sounds considerably better, peaking at around 35Hz. I’m out of wood, but I’d imagine .75 cu ft with some polyfill would be great.It fits in a 4” tall box built from 3/4” MDF. It’s the only 10” subwoofer that I could find that was less than 3” mounting depth. If you have a Golf R without a spare tire do yourself a huge favor and get one of these. Even though it’s dual 4 ohm coils rather than 2 ohm coils the amp runs it great. I’ve lost zero usable space and have bass down to about 25hz now.

This was a direct fit replacement for my 01 Suburban. I have the upgraded sound system with extra tweeters and a sub, but not the Bose system. This dropped in with no modifications and sounds way better than the 20+ year old factory sub.

I mounted a custom depth sealed box in a soffit rafter bay and have had this 10" MB Quart exposed to the exterior (albeit sheltered overhang) for over 6 years. I just pulled it off to prep for painting and it is still like new. Love MB Quart quality.Can't wait to get it back in for the patio sound system.

Been a fan of MBquart for years replaced my stock 8in sub in my Ram 1500 with this MBquart sounds real good better than stock

Good quality, perfect fit in my shallow mount box. I'm not running a competition setup, but with my current setup it has crisp, clean sound is loud enough for me.
