Bentley Continental GT JL Audio Subwoofers The owner of this 2004 Bentley Continental GT needed a serious upgrade in bass output to meet his listening preferences. Some of JL Audio’s finest products were selected to produce huge subwoofer bass while accessibility to the spare tire wouldn’t be compromised. The 12W6v3-D4 JL Audio subwoofers are known for their relatively small enclosure requirements and after loading them in a custom enclosure, the pair of subs match beautifully to a JL 1200/1v3 mono amplifier. An AudioControl LC2i converts the audio signal from the factory system into a very strong and high quality RCA output that feeds the monster JL amp.  A subwoofer volume control was custom flushed into the center console using a JL RBC1 bass knob.
