Steve Meade Designs Amplifier Audio Distortion Detector / SMD-DD-1

This Listing Includes:

• (1) Distortion Detector (DD-1)


• (1) Protective silicone rubber boot


• (1) Calibrated test tone CD


• (1) Harness

Enhance your car audio setup with the Steve Meade Designs (SMD) DD-1 Amplifier Audio Distortion Detector. This professional-grade tool allows installers and enthusiasts to precisely set amplifier gain to match the source unit’s output, ensuring clean, distortion-free sound.

The DD-1 isolates the audio signal from the vehicle’s electrical system, allowing you to measure only the true audio output without interference from charging system noise. Directly test head unit outputs, replace or repair the harness in the field, and detect distortion caused by poorly designed or malfunctioning equipment. The kit includes everything needed to get started: distortion detector, protective boot, calibrated test tone CD, and harness.

Key Features & Benefits:

• Audio Signal Isolation: Measures only the audio signal, not vehicle noise


• Direct Head Unit Measurement: Quickly test the output of any source unit


• Replaceable/Repairable Harness: Easy field maintenance if damaged
