AFETY ONCERNS We always recommend you have your Blaupunkt speakers professionally installed but the installation process is often so easy that the average consumer can achieve success with little trouble. Regardless of the person installing, you should be sure to review the following points before proceeding with the installation: READ THE MANUAL! Understanding the product and installation limitations before lifting a screwdriver.
NSTALLATION UIDELINES We strongly recommend that you have your Blaupunkt speakers professionally installed. If you choose to do your own installation please note the following important information: Before cutting any trim or metal make sure your final installation will clear all moving parts, factory cables, wires, and hoses.
