MB Quart Mb Quart Ds1-204 Discus Series 400-Watt Shallow Subwoofer (8)

Very slim installation depth. Sounds great considering it's very cheap. The "discus" trim ring is pain to remove and install. Would buy again.

Great sub, running from a small amp at 2 ohm. Puts out a decent amount of bass for only a 8”. Mounting holes did not match, but that was expected.

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 sidewall subwoofer. 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.

I installed this with the matching amp into an 8” Tahoe box and installed in my 2004 Escalade worked perfect and sounds fantastic. Fit perfect.

I ordered 4 of these subs and installed two per home tower speaker and i am very pleased with the bass.Well done M B Quart.
