A client from Midlothian recently visited Extreme Audio to inquire about upgrading the audio system and adding window tint and paint protection film to his new 2020 BMW M340i sedan. The client visited us a month before his car left the port in Europe to make all the plans. He wanted the stereo to sound great, especially at higher volumes. He also wanted paint film to prevent chips and scratches as well as window tint that would help keep the car cooler. Once he had a delivery date for the car, we scheduled an appointment to start the upgrades a few days later. Here’s a look at the work we performed for the client.
BMW M340i Audio System Upgrade
We installed an ARC Audio PS8-50 amplifier in the BMW so that we could tune the sound system in the BMW to deliver the tonal balance the client would enjoy. Typically, we remove the factory amplifier from BMWs and connect an integrated amplifier and processor solution like the PS8-50 directly to the output of the radio. In this car, the HD Radio tuner is built into the amplifier. BMW also seems to have downgraded the factory amp’s power production capabilities compared with previous models, so the addition of the ARC Audio eight-channel amp with DSP made a dramatic difference.
ARC Audio rates this amplifier as capable of producing 50 watts of power per channel. We’ve installed a number of these and we’d say it sounds more like the amp makes about 70 watts. The signal processing features integrated into the amp allow us to create amazing and complex sound systems that our clients absolutely love.
3M Scotchgard Paint Protection Film
Our 3M Scotchgard Pro Series paint protection film was a perfect choice for this amazing Alpine White car. We applied the film to the front bumper cover and the first 12 inches of the hood. These surfaces take the most abuse from stones, gravel, rocks and bugs. The film will help to absorb these impacts and prevent chips and scratches in the paint. We also applied film to the door cups and the rear edges of the doors so they won’t get chipped should they touch a wall, bollard or, heaven forbid, another car.
Scotchgard paint protection film is a completely transparent urethane film that is 8 mils thick. The film uses a strong adhesive to bond to the paint without the chances of peeling or bubbling. The film not only absorbs impacts from gravel and rocks, but it also resists staining from tar and bug splatter to help keep cars looking like new.
Premium Heat-Rejecting Window Tint

We had tinted another car for this client in the past with 3M Crystalline heat-rejecting window film. He knew he wanted that same IR rejection and UV protection for his new BMW. Our team installed 3M CR40 film on all four doors as well as the rear window. CR40 is one of the darker films in the Crystalline series and blocks 99% of UV energy to prevent potential skin damage and help to keep the fabrics and upholstery looking like new. CR40 also blocks 97% of the infrared energy in the 900-to-1,000-nanometer range to help keep the interior of the vehicle cool and ease the load on the air conditioning system.

Once we had the audio system dialed in and confirmed that the window tint and paint film on this 2020 BMW M340i were flawless, we called the client to let him know the car was ready to be picked up. He was thrilled with the sound of the stereo and loved that he could crank it up without it distorting. He was happy to have the Crystalline film on the windows and Scotchgard paint film on the body. The client was excited to finally enjoy his brand-new car.
