Our take on the Soundgate Powerstage System by Kicker
Transform your Sonic's factory sound system
You've got a great set of wheels, but something's missing: the sound of the Chevy 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 Sonic'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 Sonic'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 Sonic-specific wiring harness. Kicker's technicians measured the acoustics of the Sonic'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 on the back of the left rear seat. A 200-watt amplifier provides the power you need to feel the bass from the 10" sub in the front seat.
