Our E21 10" subwoofer enclosure is designed to utilize a single 10" woofer in the BMW E21 chassis. The combination will produce clean, clear, well-defined bass at substantial volume levels using an inexpensive woofer and moderate amplifier power
A front step is incorporated to allow the face of the enclosure to ensure a positive seal against the rear seat wall with help of our Cabin Sealed Bass technology.
INSTALLATION NOTES: Cutting metal on the rear seat wall is required to install this subwoofer enclosure. The cutting is necessary to insure port tubes and subwoofer ventilate completely into the cabin. Generally, we recommend professional installation, metal cutting and fabrications skills are required to properly install this enclosure..
While installing this does require significant vehicle modification, the results are entirely worth it. We know you want quality sound, this is your most logical solution for superb sound quality. Cabin Sealed Bass...rattle-free deep clean bass...only from G.A.S.
