What to include in your message

The more context you give us up front, the more useful our first reply will be. When you get in touch, tell us:

  • Your vehicle — year, make, model and cab or body style.
  • What's in it now — factory head unit, existing amps, or a full aftermarket system.
  • Your goal — sound quality, output, or a balanced daily-driver upgrade.
  • A rough budget range, so we can point you at the right tier of gear.

What we help with

We tune cars ourselves, and the same people answer your questions. We can help with system design from the ground up, matching components that work together — speakers to amplifier channels, subwoofers to enclosure volume — plus install and wiring questions like gain setting, signal routing and power cable sizing.

We also handle warranty and returns questions for anything you've bought from us.

Visiting Lander Ave

Our Turlock location is a working warehouse, not a walk-in showroom. Visits are by appointment only — call or email first so we can set a time and have the right gear pulled and ready to look at.

Shipping expectations

Orders ship from our Turlock, California facility. Handling runs 2–3 business days, transit runs 3–5 business days, so most orders arrive in 5–8 business days.
