About the Kicker VSS™ SubStage™ SSIEXT07

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" 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.

The SubStage SSIEXT07 fits the 2007-up Chevrolet Silverado and GMC Sierra Extended Cab, and the subwoofer installs under the passenger's side of the rear seat. This kit will not install in 2007 Classic models. It connects to the factory stereo via 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.

Big Bang for your truck

Brian from Walla Walla, WA on 1/14/2019

2009 GMC Sierra

This sub and amp combo packs a LOT more bang than I thought it would. Once you are able to balance the EQ on your head unit the balance of sound is great. Is is heavy hitting and clean. Definitely worth the purchase if you are questioning it. Install instructions could have been a little more clear on connecting to the wire harness, but that was really the only issue I had with install.

Pros: Hard hitting, clean, well balanced

Cons: Install instructions could have been more clear from the manufacturer.

easy to install, fits like a glove, sounds great, wired to right rear speaker so you can use the fader adjustment for sub input level.

Pros: the fit is great, sound is great, hooks up to rear speaker output, called kicker for info, tech support was great.

Cons: instructions for wire connection not easy to figure out, says to connect to #2 and #9 pins on connecter plug , should just say connect to front or rear speaker wires +- ( green wire + brown wire is -)

Features

Overview: Kicker's SoundGate SubStage factory audio upgrade kits are designed to fit in specific year/make/model vehicles. The SSIEXT07 is compatible with select 2007 and later GM full size extended cab pickups (please confirm fit with the Crutchfield vehicle selector, not compatible with the solid rear bench seat). Included with the system are a 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 single 10" Kicker subwoofer is loaded in a custom enclosure and powered by a 200-watt amplifier mounted to the enclosure. The included adapter harness taps into the factory stereo's wiring (for subwoofer signal input) and the power cable is connected to the accessory lug in the engine compartment. Specific wire routing instructions are included. The subwoofer is mounted under the rear seat on the passenger's side.

Electrical System: The amplifier is designed to have minimum impact on the truck'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 under the rear seat):

  • Width: 20-1/2"
  • Height: 9-1/4"
  • Depth: 16-5/8"

Q
Does this work with the factory Bose system?

Hi Kameron. I did pull up a 2007 Silverado Extended Cab with Bose, and unfortunately it looks like the VSS SubStage isn't going to be an option, but feel free to reach out to an advisor. They can pull your specific model truck, and see what could be possible for you! You can reach us via chat online, or by phone! www.crutchfield.com/I-rET1c000/contact

Q
Does this use the factory seat bolts to mount to?
[ derrick  Jan 11, 2018 ]
1 answer
A
It will! I read the subwoofer installation part of the manual and didn't see any mention of drilling new screw holes but did read where two bolts are removed and then re-installed with the subwoofer. HTH! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101
