Hertz ST 35A NEO SPL Show Series 1-7/8″ bullet tweeters

Instructions

All components must be firmly secured to the vehicle structure. Do the same when installing any custom structures you may have built. Confirm your installation is solid and safe. A component coming loose while driving may cause serious damage to the passengers, as well as to other vehicles.
Always wear protective eyewear when using tools, as splints or product residue may become airborne.
In order to avoid incidental damage, keep the product in the original packaging until you are ready for the final installation.
Do not carry out any installation inside the engine compartment.
Before starting with the installation turn the head unit and all other audio system devices off, avoiding any possible damage.
Make sure that the location you choose to install the components does not interfere with the normal operation of any mechanical or electrical devices of the vehicle.
Do not install loudspeakers where they may be exposed to water, excessive humidity, dust or dirt.
Do not install the tweeter without the protective grille.
Do not install the components or make cable run close to electronic or mechanical devices of the vehicle.
Be very cautious when drilling or cutting into the vehicle chassis, making sure there are no cables or structural elements essential to the vehicle underneath or in the selected area.
When routing cables, make sure that the cable does not come in contact with sharp edges or near moving mechanical devices. Make sure that it is firmly attached and protected along its entire length and its insulation is self-extinguishing.
Only use cables with the proper section (AWG) indicated herein.
When running the cable through a hole in the vehicles chassis, protect the cable with a rubber ring (grommet). Be sure to provide proper protection for cables running close to heat-generating devices.
Do not run the wires outside of the vehicle.
Use top quality cables, connectors and accessories such as found in the Connection catalogue.
