Corona Virus update!

We here at Extreme Car Audio Inc. have been following the state guidelines for safety as we continue to keep our store open by being clean, and safe as possible. 

Along with installing a plexiglass barrier between the counter and the showroom all staff must wear masks when in the showroom, as well as cleaning the surface areas regularly. You can also pick up your vehicle outside the showroom for “Touchless Service”.

Thanks for supporting our local business during these difficult times.

Extreme Car Audio is the leader for your Mobile Electronics needs just south of Boston in Weymouth, MA.

We have one of the largest showrooms in the region allowing you to see and touch all the latest technologies in mobile electronics. 

We are conveniently located on Route 18 near the Weymouth and Abington line.

Locally owned and operated, Extreme Car Audio has been in business since 2004, and our expert sales staff and installation experts have more than 35 years of experience in the car audio business.
