Accessories for GermanMAESTRO Car Audio products

Intelligent solutions for installing the speakers stealth in your car are as important to GermanMAESTRO as developing the speakers themselves. All our systems come with a wide range of mounting accessories.
If you prefer highlighted installation of the woofers instead of a stealth installation with the EPIC EFS speakers or any additional installation material, you can purchase the necessary grilles and rings at your authorized GermanMAESTRO dealer.
