Not sure you need a subwoofer box for your car? Or do you just not know which one to pick? Read on to see a selection of the questions we receive from customers about these products.

Why Do I Need A Subwoofer Box For My Car?



Car subwoofer boxes keep your precious sub from falling in your car, as well as optimising the sound. Depending on what you're looking for and the type of sub you have, you can find a box that will give you the perfect sound.


Can't I Just Make My Own?



Our car subwoofer boxes aren't just a cardboard box with a hole in it! They're actually precision pieces of equipment designed to boost the sound that your sub emits. Our quality MDF and carpet boxes are thicker and better quality than anything you could make at home. They're also superior to cheaper versions on the market, so it's worth investing in a quality version. For example, our 10 Inch Subwoofer Box is made from 3/4" MDF, and finished in black box carpet with gold plated terminals at either end so you can see the quality instantly. It'll bring you many years of enjoyment, giving you the chance to really make the most out of the sub you've put so much effort into choosing. 

How Do I Keep My Secure My Sub In Its Box?



All of our sub boxes have a hole in the front that's sized to fit most standard subs. If your sub is too small or you're concerned about it falling, then we offer a bass port that will keep your sub not only secure but also further optimise its sound output quality.
