I have a JBL GT120 12" subwoofer in a custom cabinet built to fit in a Dodge Stratus, and might fit well in other vehicles. This cabinet was designed specifically for this JBL subwoofer to produce low bass with a flat frequency response down to 30 Hz. Asking $150.

Note: The amplifier shown in the picture is not for sale.
