【165 S45 Separate Speakers｜Dial in Natural Highs for the Sound You Like】

These are separate (component) speakers for those who feel slightly unsatisfied with the sound of the factory speakers, or for anyone who wants the contours of vocals and instruments to be a bit clearer.

165 S45 is a separate type that uses a tweeter and a midrange separately. Using the included passive network, it plays back while dividing each frequency band. Since the output level of the high frequencies can be adjusted between 0 dB and -3 dB, it’s easier to balance the sound to suit your preferences—such as when highs feel too strong in the cabin or when you want to hear a brighter sound.

The playback frequency range is 95 Hz to 40 kHz. Including frequency bands where fine details are likely to come through—such as vocal voices, guitars, and cymbals—you can enjoy your usual tracks with a slightly different impression. This is an option for people who listen to music not only at higher volumes, but also at everyday volume levels, helping you reconsider both sound cohesion and ease of listening.

However, speaker sound isn’t determined just by installing the product. The final result varies depending on the mounting space for each vehicle model, the combination with the factory system, the condition of the door side, and the mounting base used to secure the speakers. Although the mounting opening diameter is 93 mm and the mounting depth is 40.5 mm, whether it can be installed as-is and what modifications may be needed differ by vehicle, so we first check and advise based on the actual car.

If it were me, I wouldn’t decide purely based on replacing just the speakers. Instead, I would review your current concerns about the sound and the music you typically listen to, then organize together how far you should go with modifications. If you’re considering a speaker replacement, please let us know your vehicle model and your current audio setup. Let’s figure out a way to enjoy music comfortably without any unnecessary changes.
