Review: 2005 4 runner champ! - 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.
Review: Great shallow mount subwoofer - Bought this cause I needed a shallow mount subwoofer to fit in a shallow box in a truck. Sub seems well made has good quality speaker push terminals. Sounds good for a shallow mount sub. Only 200 watts RMS but that's all I needed. Good quality subwoofer.

## Features

- Shallow mount 12-inch 400-watt car subwoofer is ideal in sealed enclosure applications and makes for a versatile subwoofer in areas with limited space
- Made with front and rear venting that allows cooler air to be exchanged in the voice coil gap, which helps the sub make deep bass
- Heavy0gauge powder coated stamped steel basket provides a solid base for the motor system and moving parts that don't consume cargo space
- Features a 2-inch high-temperature voice coil and former for high thermal stability for high performance and high-quality sounds
- UV rubber surround resists sun fading and remains flexible while the nickel-plated push and insert resists corrosion, making for easy installation

## Questions & Answers

**Q: Would a chaos erupt boss 3600 be good for it**
A: not sure but any amp with decent power should work. The main thing is having an enclosure that matches the air space the speaker calls for and making sure your ohm load configuration matches the amp.

**Q: Does this item come as a pair?**
A: No. Only one subwoofer

**Q: Can this be wired to be 2 ohms?**
A: Yes

**Q: What is the recommended enclosure size for the 12” version?**
A: Factory recommended 0.75cu ft.  Built a slightly larger box @ 0.80-085cu ft, was able to gain lower end bass in a sealed enclosure.
