Product Overview
The JBL Stage GT60041 is a 4-channel Class D car amplifier from the Stage GT Series, designed to meet a variety of system configuration needs with advanced onboard engineering features for tuning and optimising audio performance in the vehicle. The high-efficiency Class D output stage delivers 65W RMS per channel at 4Ω, 90W RMS per channel at 2Ω in full 4-channel mode, or 180W RMS bridged per channel pair at 4Ω for a 2-channel bridged configuration driving a pair of component speakers or a subwoofer, with a total peak power rating of 1240W.
The OEM Load Detect System ensures seamless compatibility with factory head units and OEM audio systems without interfering with the vehicle power grid. Start-Stop engine system compatibility maintains consistent audio output during momentary engine stops. A wide input sensitivity range on both low-level (0.2-5V) and high-level inputs (1-25V) ensures compatibility with virtually any audio source in the automotive market, with two high-level input cables included for direct OEM speaker-level connection. The variable highpass and lowpass filters (32-320Hz) provide crossover control for tailoring sound to the characteristics of the vehicle, and the variable bass EQ at 45Hz (0-12dB) provides adjustable low-frequency boost. Full onboard protection covers DC offset, overvoltage, undervoltage, overcurrent, and overtemperature. Operating voltage is 9-16V. Fused at 2 x 20A.
Features & Benefits
65W RMS per Channel at 4Ω / 180W RMS Bridged at 4Ω per Pair: Delivers 65W RMS at 4Ω and 90W RMS at 2Ω in 4-channel mode, or 180W RMS bridged per channel pair at 4Ω, providing versatile power output for front and rear full-range speakers, active component systems, and bridged subwoofer applications.
Class D Technology - High Efficiency and Low Heat Dissipation: The Class D output stage maximises power output while minimising heat generation for reliable performance in compact installation environments.
OEM Load Detect System - Factory Head Unit Compatibility: Ensures seamless integration with factory car audio systems without disrupting OEM power management, making the Stage GT60041 suitable for direct connection to factory head units.
Variable Highpass and Lowpass Filters - 32-320Hz: Both the highpass and lowpass filters are independently adjustable from 32Hz to 320Hz, providing onboard crossover control for component speaker separation and subwoofer frequency limiting from the same 4-channel unit.
Variable Bass EQ at 45Hz - 0-12dB: The variable bass EQ centred at 45Hz provides up to 12dB of adjustable low-frequency boost for subwoofer and full-range bass performance enhancement tuned to the vehicle acoustic environment.
High-Level and Low-Level Inputs with Wide Sensitivity Range: Low-level inputs accept 0.2-5V from aftermarket head units and DSP processors. High-level inputs accept 1-25V from factory OEM head unit speaker outputs. Two high-level input cables are included for direct factory speaker-level connection.
Start-Stop Vehicle Compatible: Compatible with Start-Stop engine systems for consistent audio output and battery efficiency during momentary engine stops.
Full Onboard Protection Circuitry: Protection against DC offset, overvoltage, undervoltage, overcurrent, and overtemperature conditions for long-term amplifier reliability.
Compact Footprint for Flexible Installation: Compact design for installation in vehicles with limited mounting space.

Compatible With
The Stage GT60041 is compatible with 9-16V vehicle electrical systems. Low-level inputs accept 0.2-5V from aftermarket head units and DSP processors. High-level inputs accept 1-25V from factory OEM head unit speaker outputs. Bridged operation requires a minimum 4Ω load per bridged channel pair. Stereo operation is rated to a minimum 2Ω per channel. The OEM Load Detect System ensures compatibility with factory stereos. Confirm speaker impedance against the rated output configurations before purchase.
Frequently Asked Questions
What configurations can the Stage GT60041 be used in?
The Stage GT60041 supports classic 4-channel operation (4 x 65W at 4Ω) for front and rear speaker systems, 2-channel bridged operation (2 x 180W at 4Ω) for a bridged component speaker pair or subwoofer, or a 3-channel configuration using 2 full-range channels and 1 bridged channel for a subwoofer.
Does the Stage GT60041 work with factory head units?
Yes. The high-level inputs (1-25V) accept direct connection to factory OEM speaker outputs, and the OEM Load Detect System ensures compatibility with modern factory audio systems without affecting the vehicle power management.
What is the minimum bridged impedance for the Stage GT60041?
The minimum bridged impedance is 4Ω per bridged channel pair. Do not connect loads below 4Ω in bridged mode.
Does the Stage GT60041 include high-level input cables?
Yes. Two high-level input cables are included in the box for direct connection to factory OEM head unit speaker outputs.
What wiring gauge is recommended for the Stage GT60041?
Confirm with your installer based on the 2 x 20A fuse rating and the total power draw of the installation. A minimum 10 AWG main power and ground cable is generally recommended for an amplifier at this power level.
