Custom speaker boxes are specifically designed to fit your model of BMW. Therefore, you?ll be able to install your car amplifier and sub woofer without taking up too much space, and without tearing up your interior. Instead, custom speaker boxes will blend with the interior of your BMW so that it looks like part of the original car. When choosing a fiberglass speaker box for your new system you?ll not only be getting the highest quality material producing the best sound possible, but you?ll get a light weight box that won?t add pounds on to your BMW. Custom speaker boxes work by preventing the out of phase waves from the rear from mixing with the in phase waves of the front. Therefore, when installed properly there is no resonance and a crystal clear sound can be heard from all spectrums.

The BMW speaker box product line includes a top of the line Bassforms fiberglass speaker box for the BMW 3 series, BMW 5 series, BMW 6 series, and BMW 7 series. Look for an expert staff that will assist you in choosing the right car amplifier, sub woofer, and fiberglass speaker box for your type of vehicle. Complete the sound system in your BMW and fully enjoy your beautiful ride.
