How To Fit Subwoofer In Spare Tyre Wheel Well Enclosure

A subwoofer can add extra bass thats missing in your car audio system. Subwoofers come in all sorts of sizes, the bigger usually means louder and deeper bass due to having more cone area. Now a sub needs a specific enclosure to work well, depending on your tuning and internal volume, it can take lots of space up in your trunk. This can be an issue if you are looking to build a vented style enclosure for your subwoofer. The best way if you want to take little or no space in your trunk is to place a subwoofer inside the spare tyre wheel well compartment. This has enough room for you to place a special made spare wheel subwoofer enclosure. Basically, all you need to do is form the top part of the compartment and place the sub inside it. The internal shape of the tyre well will form the shape of the enclosure.

1) Get some MDF and measure up the width and height of the car tyre well. Mark up the area leaving around 15 cm around each side.

2) Cut out the shape you have drawn out of your subwoofer onto the MDF.

3) Place your subwoofer into it, screwing it down and attaching speaker wire onto the terminals. Connect the sub to a small powered external amplifier that matches the rms output of the coil.

4) Now that you have the board that you can slot into the tyre well, all you need to do is mount it firmly by using four small screws. If you don't want to drill into the metal in your car, you can also use strong Velcro straps to do the same job.

Now the sound isn't going to be the best as a custom made ported box. After all the size of the tyre well is limited to how much space it can deliver for the subwoofer. We recommend that you use small subwoofers such as an 8 or 10 inch because the magnet takes less space up. This results in more internal volume and a better sound because the sub has more room to move internally.
