Features

Overview: This vehicle specific harness simplifies adding the Focal Impulse 4.320 amplifier to a compatible vehicle. The ISO extension cable (item number 091IMPEXT1, sold separately) must also be added to connect the amp. This adapter supplies the amp with a speaker level signal input, power, and ground, and connects the amp's output to the factory speaker wiring. (Power and ground for the amp are connected using the attached crimp connectors.) Please enter your vehicle information to confirm compatibility.

Q
I have a 2008 bmw 335xi it has the 6 connector pin and this looks like the one I need in order to install a stereo unit. Is this a conversion kit or is this just an extension?

This is for installing a specific Focal amp to your OEM radio, and not for a stereo installation. You can check to see if this will fit your vehicle by using our Outfit My Car tool: http://www.crutchfield.com/car/carselector.aspx For additional details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle.

What amp bypass harness do I need for a Becker Amp in a 2004 bmw x5 original equipment with navigation?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to see what is compatible with your factory system. They will be able to pull up your vehicle and see what integrates, and discuss other options with you.

Q
Does this work for a E46 BMW with a NAV system -- I am looking to replace the stereo but my car has two jacks and white and blue plug?

I believe you are referring to the late 90's early 2000's BMW 3 series and I believe all those have separate amps which means this will not work. If that is not your vehicle, then I recommend reaching out to an advisor by calling 1-800-324-9695 to check your vehicle
