Metra 70-1728 Amp Bypass Harness
This Metra 70-1728 harness allows you to bypass the factory amplifier in select 2006-11 Hondas with the factory-installed premium sound system. Simply unplug the connections to the amplifier, plug in the bypass cable, and connect it to the in-dash receiver of your choice. If you're not using a soldering iron, we recommend that you purchase some wire connectors to secure the connections. Check out our handy article on three ways to connect the wiring harness here.

Features
Crutchfield Wiring Harness: Crutchfield wiring harnesses prevent you from having to cut your vehicle's factory radio plug when replacing your factory radio with an aftermarket head unit. Simply solder or crimp the Crutchfield wiring harness to your aftermarket head unit's harness (solder & crimps not included), plug the aftermarket head unit's plug into the rear chassis of the aftermarket head unit, and plug the Crutchfield wiring harness into your vehicle's factory radio plug.
Note: Installation tools, hardware, & accessories are not included & sold separately. Please see the Accessories tab for recommendations & availability.
Wiring Notes: If the Crutchfield wiring harness is not equipped with a ground wire, you will need to ground the aftermarket head unit's ground wire to the metal chassis of your vehicle. Some vehicle's may require you to bypass the vehicle's factory amplifier (in another location from factory radio) or hardwire certain connections. If your vehicle is equipped with factory steering wheel controls, an additional adapter is required & sold separately.

Harness Location: The factory plug that mates with the Power Harness is located in the factory radio cavity of the vehicle. The factory plug that mates with the Speaker Harness (used to bypass factory amp) is located at the external factory amp location (below the radio, behind the console). The 17' Speaker Harness will need to be plugged into the external factory amp and then run up to your in-dash aftermarket head unit for speaker wire connection.
Note: An additional aftermarket amplifier is recommended if your vehicle is equipped with Front Tweeters, Front Speakers, Rear Speakers, & Factory Subwoofer.

Easy to install, the extra long wires are a must depending on where your factory car audio amp is located. Warning! do not cut these wires until you have established the location of your amp, measure the distance, then add an extra 8-12" inch then cut.
