Each channel pair includes:
- Adjustable Gain Control – Fine-tune input sensitivity for proper system matching.
- Variable High-Pass Filter (HPF) – Control lower frequencies reaching your speakers.
- Variable Low-Pass Filter (LPF) – Customize frequency output for your application.
- Full Range Mode – Run your speakers with a full-range signal.
- x10 Crossover Multiplier Switch – Expand your crossover adjustment range for active mids and highs setups.
The x10 crossover feature makes this amplifier especially attractive for enthusiasts building active car audio systems, high-output mids and highs setups, and pro audio stunt doors.
Whether you're chasing crystal-clear vocals, aggressive midrange output, or powerful highs, the PS-800x4 gives you the tuning flexibility to dial in your sound.
Massive Power in an Ultra-Compact Design
Space is valuable in any custom car audio installation. That's why DC Audio designed the PS-800x4 using efficient full bridge amplifier technology to deliver high power output in a remarkably small package.
Measuring just 5.51 inches long, 5.23 inches wide, and 2.3 inches tall, this amplifier can fit into tight installation spaces where traditional large amplifiers simply won't work.
It's an excellent solution for cars, trucks, SUVs, motorcycles, and custom audio builds where installation space is limited but performance cannot be compromised.
