Custom-built bass for your vehicle

Are you disappointed with the level of bass your factory system provides, but don't like the idea of installing a universal subwoofer and wiring kit? The VSS SubStage powered subs by Kicker are made to fit in specific vehicles, so you get harnesses that connect to your factory wiring, and a sub that's made to mount where your particular vehicle has space. Each system comes with vehicle-specific instructions that guide you every step of the way. The package also includes all of the wiring and hardware you need to complete the installation — that means no running to the hardware store to find a part that you didn't know you'd need.

Ready to rumble

The SubStage doesn't skimp on power and performance — it comes equipped with a 10" square sub powered by a perfectly matched 200-watt amp, all housed in a custom enclosure that's optimized for sound quality. You'll look forward to rumbling lows that can play back the biggest digital drum beat yet also deliver the low-frequency subtleties of a standup bass. Kicker's earned their reputation for making subs that crank out bass you can feel and the SubStage is no exception.

SubStage SMUS05 fits the 2005-12 Ford Mustang

The SubStage SMUS05 fits the 2005-up Ford Mustang, and the subwoofer installs on the passenger's side of the trunk. This kit only works in the Mustang coupe: it does not fit in the convertible. It connects to the factory stereo via a two wire taps for signal, and attaches to the battery for power. Please identify your car before purchasing to make sure it'll work with this package, or you can call one of our Advisors at 1-888-955-6000 to confirm fit.

Product Highlights:

  • custom-fit powered subwoofer
  • enclosure mounts on passenger's side of trunk
  • molded plastic enclosure
  • 10" woofer
  • built-in amplifier (200 watts RMS)
  • includes instructions for your Mustang and all installation parts
  • warranty: 1 year
  • Our 60-day money-back guarantee

Vehicle-specific enclosures with subs? Say what?

Instead of the usual sub in a box, the manufacturer creates a molded enclosure that fits perfectly into a convenient spot in your specific vehicle, housing a high-quality sub. Some enclosures even include a built-in amp, for the ultimate in stealth bass. The advantages? You don't lose much space (if any), your sub is perfectly matched to its enclosure, and your enclosure has a factory look that won't tell potential thieves you have an awesome sound system. Doesn't get better than that.

Good solution

Written by: Jeff from Ventura, CA on August 28, 2014

I have a 2013 Mustang GT Premium with the Shaker audio system. I wanted a solution with tighter bass than OEM and also did not want a huge box consuming all the space in my trunk. This soundgate substage seemed to be just the ticket. I can't speak to how it compares with the OEM sub in the shaker pro system, but this is a great improvement for the non-sub equipped Shaker premium system. I am delighted with the performance and the only reason I did not give it 5 stars is the lack of a separate control to adjust the bass level.

Pros: Sounds great, fits nicely out of the way preserving trunk space, plug and play kit was very complete.

Cons: No separate control for bass level

Overview: Kicker's SoundGate SubStage factory audio upgrade kits are designed to fit in specific year/make/model vehicles. The SMUS05 is compatible with select 2005 and later Ford mustangs (please confirm fit with the Crutchfield vehicle selector, not compatible with the convertible). Included with the system are a square 10" subwoofer in a custom enclosure, subwoofer amp, and all the necessary cables to power the amplifier and connect to the factory radio.

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 adapter harness taps into the factory wiring (for subwoofer signal input) behind the glove compartment. The power cable is connected to the fuse box in the engine compartment and specific wire routing instructions are included.

Electrical System: The amplifier is 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 subwoofer enclosure is custom built to fit in the trunk):

  • Width: 25-1/2"
  • Height: 15"
  • Depth: 7-1/4"
