Our take on the Soundgate Powerstage System by Kicker
Transform your Mustang's factory sound system
You've got a great set of wheels, but something's missing: the sound of the "premium" factory radio leaves a lot to be desired. Low power, less-then-ideal speaker placement, and dialed-back bass all contribute to the unhappy situation. This Soundgate Powerstage system upgrade by Kicker will transform your Mustang's stock radio and speakers into a high-fidelity sound system capable of giving you full, accurate, and richly-textured musical pleasure. And it does it without changing the look of your Mustang's interior or dash.

The digital processor/amp and the wiring
are custom-fit for your vehicle.
It plugs into your factory wiring with no cutting
The heart of the system is the Powerstage processor/amp module that plugs in between your car's stock receiver and speakers with the help of a Mustang-specific wiring harness. Kicker's technicians measured the acoustics of the Mustang's interior, then developed a program to get the strongest and cleanest audio performance possible from the stock speakers. The Powerstage module breathes new life into your vehicle's factory system, automatically correcting for the limitations of the factory speakers, then adding plenty of power so the speakers can sound their best.
Of course, there's a subwoofer with it
It wouldn't be a sonic upgrade without a subwoofer to bring bass magic to the mix. Kicker includes a custom-fit, powered subwoofer that mounts in the trunk, neatly tucked into a recess on the right side. A 200-watt amplifier provides the power you need to feel the bass from the 10" sub in the front seat. With the Shaker 500 system, the subs in your doors will keep working together with the new sub in the trunk. With the Shaker 1000 system, you'll remove the subs from the trunk, replacing them with this smaller enclosure. With either system, you'll be blown away by the improvement in the quality and power of your bass.

Do it yourself and save
This Soundgate upgrade package comes with all the hardware and brackets you'll need, and all the wiring is pre-cut and terminated to help make the installation easier. Step-by-step, illustrated instructions make this sonic upgrade a fun and rewarding project.
Shaker 1000 System Installation Note: If you're installing this package in a Mustang with the Shaker 1000 system, you'll have to remove the factory subs. You'll see the trunk's bare floor when the subs are removed, so you'll need to purchase a new trunk liner when replacing the Shaker 1000 subs.
Important Note: This upgrade package will only work with the 2012-up hardtop Mustang with the premium Shaker 500 or Shaker 1000 audio systems. It will not work in the convertible, or in a Mustang with the factory navigation radio or the basic sound system.
