JBL Club A5055 5-Channel Amplifier (4x 45W + 1x 500W)

5 channel

Valuable car amplifier with JBL power and performance.
The Club A5055 5-channel amplifier delivers a powerful 50 Watts RMS to each of the front and rear speakers in your car, and a whopping 500 Watts RMS to the subwoofer channel - a much smarter subwoofer to full range ratio than what is typical at 5- channel amplifiers. You can also bridge the amplifier to 3-channel mode to deliver 140 Watts RMS to your front speakers while driving your sub at 500 Watts RMS. Speaker-level inputs allow this amplifier to be integrated into almost any system, even one that uses your car's factory radio. Special high-pass and low-pass crossovers on the front and rear channels allow you to choose the perfect roll-off for speaker placement and cab acoustics. The subwoofer channel features a low-pass crossover, selectable bass gain and phase switch to optimize the subwoofer performance.

Features and benefits
Compact size
The JBL Club A5055 amplifier has a low profile chassis and a small overall footprint to fit more vehicles where space is limited.
High and low input
Speaker-level and low-level inputs allow the Club A5055 to be integrated into both aftermarket and factory car stereo systems.
Variable crossover and bass boost
Unlike many amps available at comparable prices, the JBL Club A5055 features variable electronic crossovers and bass boost circuitry for precise system tuning and performance.
Little noise and distortion
The Club A5055 is designed with balanced differential inputs to ensure low noise and distortion even at high output levels. This also makes it much less sensitive to line emitted engine noise.
Input level control
When using the low-level inputs, this control adjusts the input sensitivity between 200mVrms and 2.0 Vrms. When using high-level inputs, this control adjusts the input sensitivity between 2Vrms and 20Vrms.
Full protection on board
The built-in circuit protects the Club A5055 against short circuit, high temperature, over voltage and under voltage. An LED indicator is provided to let you know when any of these conditions occur.
Phase switch
This switch changes the input phase to inverted or non-inverted. This is especially useful with the subwoofer channel.
RBC wired remote control
The RBC's wired remote control is easy to install and can be mounted for convenient volume control from the driver's seat.
Class AB + D amplifier technology
The JBL Club A5055 5-channel subwoofer amplifier delivers 780 watts RMS using a
Class AB + D amplifier design to ensure high output and minimal power draw.
Switch-on mode
This switch changes DC to REM to adapt with low level signals or high level signals, this is especially useful as part of your installation remote control cable, more choice. A selectable “turn-on mode” can protect the battery to prevent power consumption when you are not expecting to turn on your amplifier.
