5. Configuració i instal·lació
Una instal·lació correcta és crucial per a un rendiment i una seguretat òptims. Es recomana fermament que la instal·lació la realitzi un professional qualificat.
5.1. Comprovacions prèvies a la instal·lació
- Compatibilitat de vehicles: Ensure the mounting locations in your vehicle can accommodate the dimensions of the SV 165 NEO (6.5") midrange drivers and ST 25A NEO tweeters.
- Requisits d'alimentació: Confirmeu el vostre amplifier can safely power these components. Refer to the specifications section for power handling.
- Eines: Gather all necessary tools, including screwdrivers, wire strippers, crimpers, drill, and safety equipment.
5.2. Muntatge
Midrange Drivers (SV 165 NEO):
- Carefully remove existing speakers or prepare the mounting location.
- Ensure the mounting surface is flat and free of obstructions.
- Position the SV 165 NEO driver and mark the screw holes. Drill pilot holes if necessary, ensuring not to damage any vehicle wiring or components behind the panel.
- Secure the driver using the provided mounting screws. Do not overtighten.
Tweeters (ST 25A NEO):
- Choose a mounting location that allows for optimal sound dispersion and imaging, typically at ear level or slightly above.
- These tweeters can be flush-mounted or surface-mounted depending on the included accessories and desired aesthetic.
- Follow the specific instructions provided with the tweeter mounting hardware for precise installation.
5.3. Cablatge
General Wiring Guidelines:
- Always ensure the vehicle's battery is disconnected before making any electrical connections.
- Connecteu el terminal positiu (+) de l'altaveu a la sortida positiva (+) del amplifier/crossover, and the negative (-) terminal to the negative (-) output.
- Use high-quality speaker wire of appropriate gauge to minimize power loss and ensure clear signal transmission.
- For the ST 25A NEO tweeters, a high-pass filter is required to protect them from low frequencies. The specifications indicate "Hi-pass filtered @ 5 kHz - 12 dB Oct." This means a crossover should be set to filter out frequencies below 5 kHz with a 12 dB per octave slope. Failure to use a proper high-pass filter will damage the tweeters.
- For the SV 165 NEO midrange drivers, a band-pass filter is typically used, allowing frequencies within their operational range (e.g., 150 Hz to 5 kHz) to pass through.
- Secure all wiring to prevent movement, chafing, and potential short circuits.
Warning: Incorrect wiring can damage the speakers and/or amplificador. Consulteu un professional si no esteu segurs.
6. Instruccions de funcionament
Un cop instal·lat, seguiu aquestes directrius per a un funcionament òptim:
- Engegada inicial: After installation, reconnect the vehicle battery. Turn on your audio system at a low volume level.
- Ajust del sistema: Ajusta el teu amplifier's gain settings, crossover points, and equalization (EQ) to achieve balanced sound. Pay close attention to the crossover settings for the tweeters (high-pass at 5 kHz, 12 dB/oct) and midrange drivers.
- Període d'entrada: Allow a break-in period of several hours of normal listening before operating the speakers at high volumes. This allows the speaker components to loosen and perform optimally.
- Control de volum: Avoid operating the system at excessively high volumes for extended periods, as this can lead to speaker damage and hearing loss. If you hear distortion, reduce the volume immediately.
7. Manteniment
These Hertz SPL Show Series components are designed for durability and require minimal maintenance:
- Neteja: Use a soft, dry cloth to gently wipe dust or dirt from the speaker cones and grilles. Avoid using harsh chemicals or abrasive cleaners.
- Inspecció: Periodically check speaker connections for tightness and ensure no wires are frayed or exposed. Inspect mounting hardware for security.
- Protecció del medi ambient: While treated for UV and water resistance, protecting the speakers from prolonged direct sunlight and extreme moisture will extend their lifespan and maintain aesthetic appearance.
8. Solució De Problemes
If you experience issues with your Hertz SPL Show Series components, refer to the following common problems and solutions:
8.1. No hi ha so dels altaveus
- Comproveu les connexions: Ensure all speaker wires are securely connected to both the speakers and the amplifier/head unit. Verify correct polarity (+ to + and - to -).
- AmpEstat de l'abonament: Comproveu si el amplifier is powered on and not in protection mode.
- Source Unit: Confirm the head unit or source is powered on and playing audio.
- Fusibles: Check fuses in the amplifier and vehicle's fuse box.
8.2. So distorsionat o poc clar
- Nivell de volum: Reduïu el volum. Sovint es produeix distorsió quan ampL'amplificador o els altaveus estan saturats.
- Configuració de guany: Ajusteu el amplifier's gain settings. Too high a gain can cause clipping and distortion.

- Cablejat: Check for loose or shorted speaker wires.
- Danys de l'altaveu: Inspect speaker cones and surrounds for any visible damage.
8.3. One Speaker Not Working
- Individual Connections: Check the wiring for the specific non-working speaker.
- Balanç/Fader: Ensure the balance and fader settings on your head unit are centered.
- Amplifier Channel: If using a multi-channel amplifier, test the output of the specific channel connected to the non-working speaker.
If problems persist after troubleshooting, contact Hertz customer support or a qualified car audio technician.
