Audio Control has built a reputation on solving the problems that other brands leave behind, and at Audio Express Inc in Longview, Washington, that's exactly why we carry them. Their digital signal processors and line output converters give our technicians the tools to work with complex factory audio systems and deliver results that sound the way they should. Whether we're integrating a new amplifier into a vehicle that came with a factory DSP, or tuning a full custom system from scratch, Audio Control gives us the precision to get it right. Washington drivers who bring their vehicles to us for OEM integration work see the difference firsthand.
