Performance Meets Practicality in Compact Car Audio Design

Robust Construction with Integrated Protection

Encased in a powder-coated die-cast aluminum enclosure, the USW‑80L offers both structural integrity and functional elegance. The integrated protective grill guards both the 8-inch subwoofer and internal amplifier against daily wear, while the internal cooling system supports consistent performance during extended use.

Deep Bass and Tuning Flexibility with Advanced Audio Features

Built-In Controls for Tailored Output

This model comes equipped with a variable 50Hz–150Hz low-pass crossover and a matching 45Hz bass boost, allowing fine-tuning to match your system's acoustics. Additionally, a signal phase switch ensures phase alignment within any setup.

Input Versatility with OEM Integration

Whether you're upgrading a factory system or installing a fully custom build, the USW‑80L supports both RCA line-level inputs and speaker-level inputs. The integrated 1.3V signal sensing turn-on feature makes this sub compatible with OEM audio systems, eliminating the need for separate turn-on wiring.

Dual Passive Radiators for Balanced Output

Built with dual passive radiator woofers, this subwoofer enhances low-frequency response without requiring a ported design, providing greater bottom-end output and reducing unwanted vibration and enclosure fatigue.

Multi-Color LED Lighting for Dynamic Visual Appeal

LED Ring with Customizable Color Options

A distinctive ring of 26 ultra-bright LEDs embedded within the subwoofer’s translucent grill adds ambient lighting to your vehicle’s interior. Choose from seven solid colors or switch to an automatic color-changing mode. Activate pulse mode to synchronize the light pattern with the beat of your music using the onboard programming button.

Fine Control at Your Fingertips

Wired Remote Gain Control

The included remote gain knob provides driver-side control over bass levels, making real-time volume adjustments simple and safe without requiring access to the main unit.
