Low noise and distortion

The Club A5055 has been engineered using Balanced Differential Inputs to ensure low noise and distortion even at high output levels. This also makes it far less susceptible to line induced radiated engine noise.

Club A5055 Input Level Control - Image

Input Level Control

When the low-level inputs are used, this control adjusts the input sensitivity between 200mVrms and 2.0 Vrms. When high-level inputs are used, this control adjusts the input sensitivity between 2Vrms and 20Vrms.

Value engineered 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 pounding 500-Watts RMS to the subwoofer channel — a much smarter ratio of subwoofer-to-full-range power than what is typical in 5-channel amps. You can also bridge the amp to 3-channel mode to deliver 140-Watts RMS to your front speakers while driving your sub with 500-Watts RMS. Speaker-level inputs allow this amplifier to integrate into almost any system, even one using your car's factory radio. Separate high-pass and low-pass crossovers on the front and rear channels allow you dial in the perfect roll off to best suit speaker placement and cabin acoustics. The subwoofer channel features a low-pass crossover, selectable bass boost, and phase switch to optimize subwoofer performance.

The remote bass adjust is very non-linear. From 0 to 1/4, it is normal, from 1/4 to 1/2, there is little difference. From 1/2 to max, there is no difference. I have tried with a variety of gain and bass boost settings and switching sub impedance.

I was gonna get a one GX Series 12" Single-Voice-Coil 4-Ohm Subwoofer and wanted to know if this amp will run it reliably, I also put 2gx coaxial in the rear and 2 gx components in the front with tweeters, wondering if this amp will run all of this.

Besides the missing wiring, does this amp need anything else to connect with a factory system ? 

Asked by: Anthony_25
Our JBL Club A5055 has three pairs of RCA jacks are provided for the input Front, Rear, and Subwoofer, with the Front and Rear inputs also accepting high-level signals. If using high-level, 4 speaker wire-to-RCA adapters are provided. Aside from the speaker wiring, there's nothing else needed.
