ABSTRACT:
The use of regular size woofers for motor vehicle loudspeaker application is made possible by utilizing the rear windshield space in the vehicle. High fidelity low frequency sound and deep-box effect result without sacrifice of space in the passenger compartment. A rear view window and windshield can be incorporated in the sound box to retain rear viewing capabilities from the driver's seat.
