Most OEM speaker systems cannot completely satisfy the expectations of sophisticated customers.
Especially the basic equipment leaves a lot of space for improvements of dynamics and sound quality.
Installing car specific aftermarket speakers is a simple way to enhance the audio system.
GROUND ZERO´s line of CAR SPECIFIC solutions consists of various components designed for upgrading the OEM audio systems of modern cars easily.
