Comments on How to Install Subwoofers in a Car

Most people think that you can only cover the port holes to get more bass. But you can line you box with stuff. I at first thought the eggshell foam stuff would work, but there is no difference, so I loaded it with a whole bunch of cotton and my 2 10's never sounded better.

Make sure when you build a box for your sub woofer that you have a tight, well enclosed space behind the magnet. Make sure to use thick wood, like MDF, and seal all edges with silicone. If placing the subs upside down, do the same, but place the front of the sub into the box. Make sure you do the opposite, and leave as little space as possible so the magnet can kick out into the interior.

The main thing when you get the sub is where and how you place it. For Bazooka's, point it to a corner and play around with the distance in the corner. You might be surprised with the difference. If you have a normal sub-place it facing the back of the car. After this find a way to secure it in place (using belts or some high friction clot ( any wool cloth ). Remember the base travels through the boot to the car and then to you. So it's how well you tune it with respect to the car. Use the sub woofer filter if you have on. For high power subs, around 85Hz is good.

If your box has holes in it for tweeters, you can do one of two things. One, you can get tweeters installed by a professional or if you bought the box separately do it your self. Or, you can cover the holes with pieces of plywood so the air in the box won't escape. The less air escaping means more boom in your trunk.

First, always make sure you seal the box (as well as your sub) when you have it positioned the way you want it. Then make sure you use the proper depth screw. Too big of a screw sticking out will actually loosen the seal and the screws will eventually come out. I like to use coarse, dry wall screws. It depends on the thickness of your box and sub mount. You may also want to go with the 1/4 bolts and give it that cool metal look as well. But I would use rubber washers under the regular washers to keep a really good seal. The other thing you may want to consider is mounting your sub upside down in your box. Sometimes it works better.

The vibrations from the subwoofer may make the license plate rattle as well. A license plate cover may fix this problem.

The main problem people have with subs is trunk-rattling. This is because your trunk doesn't provide enough free air space. It is working like a sealed sub box itself. Try turning it into a ported one. Use vents and ports to let out some of the pressure.

Worried about buying expensive subwoofers and having them stolen because they are always on show? Consider ditching the box and placing the subwoofers underneath the rear seats. This is also good if you have several places that vibrate, because the subwoofers are secured tightly. In addition, there's hardly any loss of quality.

Use rivets to secure your subwoofers, this makes stealing them a lot harder. Also secure the box nicely. There is no point in riveting your woofers to the box if thieves can take them to their garage and drill them out.

Lock your back doors and the trunk of your car. Do this so that the handle next to the drivers side doesn't unlock the trunk and they can't get in through the back seats (otherwise leaving your system helpless). This way, the only way in is with a key, which they don't have.
