4. Setup and Installation

4.1. Mounting

These speakers are designed for door mount installation. Ensure the mounting surface is flat and rigid enough to support the speaker's weight and withstand vibrations.

1. Choose Location: Select a suitable mounting location that allows for proper speaker depth and clearance.
2. Cut Opening: Using a template (often provided with the speakers or available from the manufacturer), carefully cut the mounting hole. Ensure the hole size matches the speaker's dimensions (approximately 6.5 inches in diameter).
3. Drill Pilot Holes: Drill pilot holes for the mounting screws around the perimeter of the opening.
4. Secure Speaker: Place the speaker into the opening and secure it with the provided screws. Do not overtighten to avoid damaging the speaker frame.

4.2. Wiring

The Hertz 6.5-inch coaxial speakers operate at 4 Ohms impedance and are rated for 100 Watts maximum output. Proper wiring is crucial for optimal sound quality and to prevent damage to the speakers or your audio amplifier.

1. Identify Terminals: Locate the positive (+) and negative (-) terminals on the back of each speaker. These are typically marked.
2. Connect Speaker Wires: Connect the positive wire from your amplifier to the speaker's positive terminal and the negative wire from your amplifier to the speaker's negative terminal. Ensure correct polarity for all speakers.
3. Secure Connections: Use appropriate connectors (e.g., spade terminals, crimp connectors) to ensure secure and corrosion-resistant connections, especially in a marine environment.
4. Test System: Before fully reassembling, perform a low-volume test to ensure all speakers are functioning correctly and the sound is balanced.

Once installed and wired, your Hertz marine speakers are ready for operation. The sound quality and volume control will be managed by your connected audio source (e.g., marine stereo head unit, amplifier).

• Power On: Turn on your marine audio system.
• Adjust Volume: Start with the volume at a low level and gradually increase it to your desired listening level.
• Audio Settings: Use your audio source's equalizer and balance/fader controls to fine-tune the sound to your preference.
• Avoid Distortion: If you hear any distortion, reduce the volume immediately to prevent speaker damage.
