Space-age power
Although it looks like it belongs in the cockpit of a stealth bomber, JBL's Club 1kW mono subwoofer amplifier can actually deliver up to a blistering 1,000 watts RMS to your subwoofer. The Class D amplifier design ensures the amp's high output won't put too much 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 — and JBL includes RCA-to-speaker wire adapters so you'll make the right connections. 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.
