METRA 70-1120 Radio Wiring Harness Volvo 82-97 Amp Bypass

SKU CH-B6M2-F3QVA

Connects an aftermarket stereo to Volvo 82-97 factory wiring while bypassing the amplifier

  • Plugs directly into the factory Volvo harness for quick setup
  • Bypasses the original amplifier to power four speakers cleanly
  • Built with quality materials for reliable long-term connections
  • Designed for Volvo models from 82 through 97
  • Simplifies aftermarket radio installation without cutting wires

Vehicle Application

The Metra 70-1120 wiring harness connects an aftermarket stereo to the factory radio plug in Volvo vehicles built between 82 and 97. It is designed for installers who want to retain the original amplifier while replacing the head unit.

Amp Bypass Function

The harness routes speaker-level signals past the factory amplifier so the new radio drives the speakers directly. This avoids the noise and compatibility issues that can occur when an aftermarket head unit feeds a legacy amplified system.

Connector Compatibility

The 70-1120 plug matches the specific Volvo radio connector used during the 82-97 production years, ensuring a direct fit without cutting or splicing the vehicle harness.

Questions about this item

Will the 70-1120 harness generate any noise or heat when powering four speakers continuously?

The harness is a passive wiring adapter with no active electronics, so it produces no heat or audible noise during all-day operation.

What existing Volvo wiring must be present for the 70-1120 to plug in at the radio location?

The vehicle must retain its original factory radio connector from the 82-97 Volvo harness so the 70-1120 can mate directly at the radio opening.

Can the 70-1120 work alongside the original amplified system in an 82-97 Volvo without rewiring the speakers?

Yes, the harness is designed as an amp bypass, allowing an aftermarket radio to drive the four speakers directly while leaving the factory amplifier disconnected.
