Unique-Bargains Subwoofer Amplifier Harness 20-pin 18.7cm

SKU CH-2Y8M-1EQC4

A 20-pin wiring harness connects a subwoofer amplifier to factory radios in select Nissan, Subaru and Infiniti models from 2007 to 2020

  • Adds subwoofer output to factory radio using 20-pin harness
  • 7 cm cable reaches amplifier without strain
  • Metal and plastic construction resists corrosion and breakage
  • Direct replacement fits Nissan and Subaru models listed
  • Plug-and-play design installs without cutting factory wiring

Vehicle Compatibility

This 20-pin wiring harness connects a subwoofer amplifier to the factory radio in listed Nissan, Infiniti, Subaru, Mazda, Ford and Chevrolet models from 2007 to 2020. It provides RCA output and a power lead so an external bass amplifier can be added without cutting the original loom. The plug-and-play design replaces a broken or missing factory harness directly.

Installation Scope

The part suits owners adding a subwoofer amplifier to a compatible vehicle and wanting a direct factory-style connection. It does not suit vehicles outside the listed model years, nor installations that require a different pin count or connector shape. Builders needing signal integration for aftermarket head units should look at a different interface.

Connector Pin Count

The harness uses a 20-pin connector matched to the factory amplifier plug on the supported vehicles. Verify that the original harness in the vehicle also carries 20 pins before ordering.

Questions about this item

Will this 20-pin harness work with the factory head unit in my 2012 Nissan Altima?

Yes, the harness is listed for Nissan Altima 2007-2018 and plugs directly into the factory radio connector to feed an external amplifier.

How can I verify the RCA output is delivering a clean signal to my amp after installation?

Play audio through the factory system and confirm the subwoofer amplifier powers on and reproduces bass without noise or clipping at moderate volume.

Does the package include the RCA cables and power wire needed to reach the amplifier in the boot?

The box contains only the 20-pin harness assembly; RCA cables and a power lead for the amplifier must be purchased separately.
