Installation Tips

Mechanical Installation

Warning: Before mounting, disconnect the negative pole (-) of your car battery. Check all connections for correct polarity; incorrect polarity can cause short circuits in the vehicle's electrical system.

The best installation positions are the original factory locations for originality and ease of mounting. Ensure the speakers are installed flush and securely. The quality of the installation significantly impacts the sound; therefore, attention should be paid to damping and careful installation.

Protect the speakers from heat, direct sunlight, mechanical influences, moisture, and wetness using accessories from AUDIO SYSTEM.

Attention: Route your cables straight, avoiding pinching or running them over sharp edges, as this can cause short circuits or damage to your entire installation.

Caution: When removing interior trim panels, fastening parts may be damaged and will need replacement.

Important: The correct polarity of the speakers relative to each other is crucial for the sound quality. For example, reversing the polarity of the tweeters might improve the sound. Experimentation, listening, and measurement are recommended to achieve the best results.

Frequency Response and Impedance

The graph displays the speaker's performance characteristics. The frequency response shows the sound pressure level (SPL) in decibels (dB) across a frequency range from 250 Hz to 12000 Hz. It indicates a sensitivity starting around 70 dB at 250 Hz, peaking near 90 dB around 1 kHz, and gradually declining to approximately 75 dB at 12 kHz.

The impedance curve, measured in Ohms (Ω), illustrates the speaker's electrical resistance across the same frequency range. It shows a resonance peak around 90 Hz, consistent with the specified resonance frequency (Fs). Above this peak, the impedance generally settles around 5-6 Ohms, with minor fluctuations up to 12 kHz.
