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.

processor/amp with wiring

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.

mounts in the trunk.

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 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.

Features

Overview: Kicker's SoundGate PowerStage factory audio upgrade kits are designed to fit in specific year/make/model vehicles. The PMUSP12 is compatible with select 2012 and later Ford mustangs having the factory premium Shaker sound system (please confirm fit with the Crutchfield vehicle selector, not compatible with the convertible or the factory navigation system). Included with the system are a square 10" subwoofer in a custom enclosure, subwoofer amp, multi-channel amp with custom mounting brackets, all the necessary cables to power the amplifiers, and adapter plugs to connect to the factory radio and speakers without cutting into any of the factory wiring.

Multi-Channel Amplifier: The multi-channel amplifier is rated at 50 watts RMS x 4 channels and powers the front and rear factory speakers. The amp also has a built-in computer-optimized, 32-bit DSP (Digital Signal Processor) programmed specifically for the car's interior and factory audio system. Custom brackets are bolted to the amp to mount it behind the glove compartment. The included wiring harness has adapter plugs that connect between the factory radio and factory harness, so cutting/splicing/testing the existing wires is not necessary. The included power harness is connected to the fuse box in the engine compartment, and specific wire routing instructions are included.

Subwoofer: The custom enclosure is loaded with a single, square 10" Kicker subwoofer, powered by a 200-watt amplifier mounted to the enclosure. The subwoofer is mounted in the trunk on the passenger's side and the included wiring harness has an adapter plug that connects to the multi-channel amp's harness (for subwoofer signal input). The power cable is connected to the fuse box in the engine compartment and specific wire routing instructions are included.

Electrical System: Both amplifiers are designed to have minimum impact on the car's charging system.

Dimensions: The listed dimensions do not include the mounting brackets (regardless of these measurements, the amplifier mounting brackets and subwoofer enclosure are custom built to fit in the vehicle):

  • Amplifier:
    • Width: 8-1/4"
    • Height: 1-3/8"
    • Depth: 6"
  • Subwoofer Enclosure:
    • Width: 25-1/2"
    • Height: 15"
    • Depth: 7-1/4"

Big bass and better sound

Written By Wow., Charlotte, NC on Sunday, July 27, 2014

Crutchfield Customer Review (What's this?)

Installed in my son's 2012 mustang. Changed all speakers to infinity. Reference and Kappa. The added bass in the trunk balances the sound and the increase in bass in the door is great. Well balanced and it sounds phenomenal, Country, rap or rock. Gotta give it up to Kicker. Never thought it would work this well.

Pros: Sounds balanced and strong,

Cons: Install took longer than expected.

Sweet upgrade from factory

Crutchfield Customer Review (What's this?)

I installed the Soundgate system in my 2012 Roush RS3 Mustang. This car was made to be loud (great sounding exhaust) but the stereo was not .They say this system will make the stock speakers sound good but I am a Infinity fan and the stock weak speakers have to go.I replaced the door and rear deck speakers with Infinity REF-8602cfx from Crutchfield .I left the stock door subs unhooked under the door panel and pulled the stock amps fuse. I used a Dynamat type product on the rear deck,spare tire well,trunk area, and doors.For me the sound deadener is so important it keeps the sound crisp and tight.The harness fits like a glove .The amp a little tricky to mount but if I can do it you can do it .The amp is stealthy and runs cool.The sub mounted perfectly, nice and neat in the right rear corner.The sound quality KICKS.I am very pleased with this package.

Pros: Sounds great with plenty of power ,it kills the stock setup.Straight forward install.

Cons: Amp mounted close to fuse box- it makes it very hard to remove the small plastic cover over the fuses.
