Installation Notes

For the best performance, install the G3600.1D using high-quality OFC power and ground wiring sized appropriately for the amplifier's current demands.

The built-in High-Level Inputs make this amplifier an excellent option for both aftermarket and factory radio installations, while the included Remote Bass Level Control allows convenient adjustment of subwoofer output from the driver's seat.

During setup, properly adjust the amplifier gain and crossover settings to match your subwoofer system. Utilizing the built-in clip indicator can help prevent distortion and reduce the risk of damaging your equipment.

Pro Audio Center Tip

One of the most common misconceptions is choosing an amplifier based solely on its maximum power rating.

For real-world performance, always compare an amplifier's RMS output to your subwoofer's continuous power handling. The G3600.1D delivers 1,200 Watts RMS at 1 Ohm, making it an excellent choice for many premium aftermarket subwoofer systems while providing clean, controlled bass for everyday listening.

A properly tuned 1,200-watt RMS amplifier will typically outperform a poorly matched amplifier with a much higher advertised peak power rating.

Build Your System

Complete your installation with:

• OFC 4 AWG amplifier wiring kit
• High-quality RCA cables
• Sound deadening material
• AGM battery upgrade (recommended for demanding systems)
• Custom sealed or ported subwoofer enclosure
• Premium line output converter (when retaining a factory radio)
• Additional battery or upgraded charging system for larger multi-amplifier builds
