Space-age power

Although it looks like it belongs in the cockpit of a stealth bomber, JBL’s Club 5501 mono subwoofer amplifier will actually deliver up to 550 watts RMS to your subwoofer. The Class D amplifier design ensures the amp’s high output won’t put any strain your vehicle’s electrical system.

Works in almost any vehicle

Speaker-level inputs allow this amplifier to integrate into almost any system, even one using your car’s factory radio. You can use the low-pass filter and variable bass boost to maximize the performance of your subwoofer and enclosure, while a phase switch ensures that the bass will blend well with your full-range speakers.
