Product Identity

The Metra 70-7305 is a wiring harness designed to bypass the factory amplifier in select Hyundai and Kia vehicles from 2010 onward. It allows an aftermarket stereo to connect directly to the vehicle's existing wiring plug. The harness is built from OEM quality materials for a reliable connection. It is intended for installers who want to retain the original amplifier while upgrading the head unit.

Vehicle Compatibility

This harness suits owners of compatible Hyundai or Kia models who are installing an aftermarket radio and wish to keep the factory amplifier active. It is not for vehicles outside the listed application range or for installations that require a full amplifier bypass with new speaker wires. Buyers needing a different connector pinout or a non-amplified signal path should verify their specific vehicle application before purchasing.

Key Specification

The defining specification is the amplifier bypass function that plugs directly into the vehicle's factory harness. This design routes the aftermarket stereo's outputs through the OEM amplifier without cutting or splicing the original wiring. Correct vehicle fitment depends on the specific 2010-Up Hyundai or Kia application. Confirming exact compatibility ensures the harness matches the factory connector and wiring scheme.

Questions about this item

What factory connector does the 70-7305 plug into on my Hyundai or Kia?

Will the 70-7305 let me keep the original amplifier when fitting an aftermarket stereo?

Yes, the harness is designed for amplifier retention so the OEM amplifier stays active and drives the speakers after the new radio is installed.

With the ignition on, the aftermarket radio should power up and all speakers should play audio through the factory amplifier without distortion or channel loss.
