The adapter is specifically designed to fit a wide range of speakers with a 158mm bolt circle, including popular models such as the Skar TX65, ensuring a secure and stable mounting.
For a seamless installation, the adapter requires M4 nuts and fixing material. It is designed to provide an optimal fit, so you can easily integrate your new speakers into the vehicle's existing structure.
