Crystal Audio Solutions (CAS) is a family-run car audio retailer and system-planning resource based in Tumwater, Washington. Since 2015, CAS has helped customers build louder, cleaner, and more reliable systems with straightforward product guidance and personal support.
We work with daily drivers, loud street builds, demo vehicles, and competition-oriented systems. The goal is not simply to sell individual parts; it is to help customers choose equipment that works together in the vehicle.

Complete-System Planning
A car audio system performs best when the amplifier, subwoofers, enclosure, wiring, battery bank, and charging system are planned together. CAS helps customers review RMS power, voice-coil wiring, final ohm load, alternator output, battery support, wire size, fuse protection, and vehicle fitment before ordering.
If you are unsure what will work together, use Build My System and send us your vehicle, equipment, electrical setup, goals, and budget. You can also use the free CAS Knowledge Center calculators for amplifier gain, current draw, alternator size, subwoofer wiring, cone area, enclosure volume, and wire/fuse planning.
Small-Business Service
Crystal Audio Solutions is operated by two dedicated professionals who take pride in direct, personalized support. Customers can shop online throughout the United States and contact CAS when a build needs fitment or system-matching help.
