  • (1)DS18 Plug & Play Harness for JK/JKU Audio Systems Under Seat Amp Rack JK-HARNESS

The JK-HARNESS is an essential piece of equipment for any JK/JKU Jeep audio system with fully loaded sound bar.

This Plug and Play Harness connects the 8-inch midrange speakers directly to the DS18 aftermarket amplifier, while the plug-and-play harness utilizes your factory amplifier to push the Tweeters and drivers. This harness is designed to get the proper power and cable routing without the need for cutting, splicing or adding of additional wires to your factory harness to power your high-range speakers.

The Plug and Play capabilities of this harness are only available to Jeeps with BASIC Sound Systems. If trying to connect to anything other than the Jeep factory BASIC sound system, the plug and play connectors must be cut and spliced at the harness connection or bypassed to the DS18 Amplifier.
