JBL Stadium 4
Translation missing: en.products.product.pickup_availability.unavailable
Class D Design
Every Stadium amplifier, including the full-range models, features high-efficiency Class D topology. This technology allows JBL to engineer amplifiers that are more compact, generate less heat, and draw less current from the vehicle's electrical system.
Low Distortion
JBL Stadium amplifiers have been engineered to deliver the lowest distortion possible, enhancing the audio experience regardless of output level.
Full On-Board Protection
JBL Stadium amplifiers have on-board circuitry to protect from shorts, temperature, overvoltage, and undervoltage. An LED indicator is included on all five models to let the user know when one of these conditions exists.
Proprietary High-Conductivity Terminals
All JBL Stadium amplifiers come equipped with a newly introduced E.A.R.L terminal for better grounding. For 5-channel and mono amplifiers, an adapter connector is available in the box for easy installation.
Compact footprint
With it becoming more and more difficult to find spacious locations for amplifier mounting, JBL Stadium amplifiers have been developed in a small compact form factor to allow more location versatility.
Sleek design
Sometimes, an amp can be as stylish as it is powerful. JBL Stadium amplifiers have a clean, streamlined industrial design.
Full-Range Line Outputs
The full-range Stadium amplifiers (Stadium 5, Stadium 4, and Stadium 2) include full-range line outputs. This allows the audio signal to be routed to additional amplifiers or self-powered subwoofer solutions, increasing your system configuration options.
