Finding suitable replacement speakers for an older car can be a frustrating endeavor. Many older models, like the 1997 BMW 318ti, require parts that are no longer in production. But thanks to the power of 3D printing and the generosity of fellow BMW owners, there is now a solution.
In the past, BMW owners would rely on specific brands that provided plug-and-play replacement speakers with proprietary connectors. However, these options often weren’t compatible with the unique speaker configuration of the 318ti. This led to a search for alternative solutions, with forum threads dating back years discussing the challenges and expensive adapters required.
Then, in 2018, an engineer and graphic designer named Andrew Curtin came to the rescue. He uploaded a free STL file of a 3D printable adapter bracket to Thingiverse, a popular online platform for sharing 3D-printable designs. With this adapter, owners could now easily mount standard 5.25-inch speakers onto the back panels designed for 4-inch speakers.
The adapter features a simple circular design with strategically placed holes for mounting onto the car’s panels and securing the larger speakers. Additionally, it utilizes the existing fasteners from the stock plastic assemblies to angle the speakers towards the passengers. Although the free adapters do not provide the same angling functionality as the original speakers, it’s a small compromise compared to dealing with blown-out speakers.
To obtain the adapters, BMW owners simply need to download the files, either print them at home if they have access to a 3D printer or visit a local university or library that offers 3D-printing services. The cost is minimal, often as low as 10 cents per gram of material used. This affordable option makes it an ideal solution for those looking to upgrade their car speakers without breaking the bank.
As for the speaker replacements themselves, many individuals have found success with standard 5.25-inch speakers that are readily available and more affordable than specialized options. By replacing the BMW’s speaker connectors with female spades, the larger speakers can seamlessly integrate with the car’s audio system.
Thanks to the creativity of the 3D printing community and the accessibility of printing facilities, the struggle of finding compatible speakers for older cars like the 318ti has been resolved. So, if you’re tired of subpar sound quality in your beloved vehicle, consider exploring the world of 3D printing to elevate your audio experience.
