iDatalink Maestro HRN-DSP-TO1 DSP/Amplifier T-Harness for Select Non-Amplified Toyota, Scion & Subaru Vehicles

The iDatalink Maestro HRN-DSP-TO1 DSP/Amplifier T-Harness for Select Non-Amplified Toyota, Scion & Subaru Vehicles connects a supported vehicle factory-audio system to an application-approved Maestro amplifier-integration solution. It is a vehicle-specific harness—not a standalone amplifier interface—and the exact factory audio configuration matters.

At a Glance

• Vehicle-specific plug-in T-harness for the exact applications and factory-audio configurations listed below
• Connects at the supported factory radio or amplifier location without cutting the vehicle-side audio connectors
• Supports a source-data-approved Maestro AR, AR2, or DSR1 amplifier-integration solution when programmed for the exact vehicle
• The compatible Maestro interface, aftermarket amplifier or DSP, power wiring, signal wiring, programming, and tuning are sold separately
• Designed for listed vehicles without a factory amplifier; do not order for an amplified version unless the exact application row says otherwise
• After installation, the factory radio does not directly power the speakers; suitable aftermarket amplification is required
• Vehicle-specific firmware and the current installation guide must be followed; retained functions vary by application

Vehicle Compatibility

Use the table below to find the row that matches your vehicle and factory equipment. The year, make, and model must match, along with the listed factory amplifier, premium-audio brand, navigation, screen, or other equipment details. If your vehicle does not match a row exactly, contact MCOR before ordering.

Compatibility & What You Need

Important purchasing requirement: This harness is one component of a complete amplifier-integration system. Select the exact application-approved Maestro interface (ADS-MAR, ADS-MAR2, or ADS-DSR1), then add the required aftermarket amplifier/DSP equipment, amplifier wiring, speaker connections, programming, and professional system configuration. It is for the listed non-amplified factory systems and does not turn the factory radio into a speaker-power amplifier.
