2006-2012 BMW 3 Series Sub Box Rear Fire Sealed E90 E92


2006-2012 BMW 3 Series Sub Box Rear Fire Sealed E90 E92

The 2006 BMW 3 Series has always been a popular platform for people to fix up and a stereo is one good way to do it. This box is designed to fit in snugly against the back of the rear seat and fire towards the rear of the car and can hold 1-2 10 or 12 inch subs. This design is for maximum airspace and the depth of the box can be reduced if desired. This depth allows full access to the storage bin in the floor of the trunk and comes right to the edge of the floor storage lid. Custom ported enclosures can be made, too, so feel free to contact me with any requests.

This is a sealed subwoofer box. A sealed subwoofer box has a tight and punchy bass that is more articulate and more true to the music with a more natural sound. For customers who want louder deeper bass with the lower bass more pronounced, a ported box is what you want. Because of the ported design, the bass will not be as tight and punchy, but there is double the bass of a sealed box with the same subs. If big bass is what you want then our ported box will be what you want.

This box is made out of 3/4″ MDF and is fully carpeted in matching carpet. The nickle plated spring loaded speaker terminals are mounted on the back of the box and the speaker wires are soldered on for a solid and reliable connection.
