About Westminster Speed & Sound
Westminster Speed & Sound is conveniently located just 20 minutes north of Baltimore, Maryland. We are the most awarded vehicle technology specialist in the Mid-Atlantic. Since 1969, we’ve provided the kind of service that keeps our clients coming back. We are now honored to serve our third generation of customers.
Our first love is upgrading vehicle audio systems. Porsche is our premier focus, along with Audi, BMW, Mercedes, and VW. Of course, we work on domestic and Asian brands as well, and you’ll often find pickup trucks in our bays based on our geographic location. Jeep and Bronco owners have come to love our stereo upgrades that make their vehicles enjoyable for hours of driving.

Harley-Davidson audio upgrades is another area of specialty for us — we’ve been upgrading audio and lighting on them since 2000. If you own a Can-Am, Indian, BMW, or other powersports vehicle, we’d be happy to discuss solutions for those as well.
Security systems have been one of our specialties since 1990. Whether you’re looking for a remote car starter, a standalone system, or one paired with an alarm, we’ve got you covered.
Our Appearance Division has been in operation since 2000 and offers window tinting, paint protection film, and ceramic coatings.
Our Safety Division provides the finest-performing dash cameras available, along with rear and forward-facing cameras and parking sensors.
Our Accessory and Truck Division, active since 1969, offers a wide selection of bed covers, side steps, hitches, WeatherTech products, and auxiliary lighting.


We’re proud to house one of the most unique and best-sounding car audio listening rooms in the country. In fact, we are one of only three shops nationwide with a dedicated demo space designed to showcase the benefits of digital signal processors for car audio systems.
Of course, nothing beats a demo in a real vehicle. On any given day, we have several cars and trucks equipped with various systems so you can see and hear what’s possible. Maintaining a demo vehicle fleet is a significant investment, but we believe it’s a vital part of who we are and what we do.

At Westminster Speed & Sound, we take our relationship with you seriously. You are the reason for our success since 1969, and we’re committed to giving you the best buying experience possible. Whether you need a simple stereo repair or a full “concert on wheels,” you’ll be treated with fairness and respect.
We offer professional installation on nearly everything we sell. Our highly skilled technicians are equipped with the specialty tools they need to do the job right the first time. From commercial-grade laser CNC machines to 3D printers, we use cutting-edge technology to deliver installations that look and function like factory-installed systems.
I encourage you to call us, contact us, or stop by. We’ll walk out to your vehicle, look it over together, and get to know your goals. Then we’ll recommend the best products to help you achieve them. And we’ll back it up with outstanding customer service after the sale. We’re not in this for a one-time transaction — we’re here to build long-term relationships.
I’m confident you won’t be disappointed.
