【165 S45A｜Separate Speakers to Tune the Sound Inside Your Car】

If you want a bit more clarity from the factory speakers and would like to better perceive the positions of vocals and instruments, then 165 S45A is something you should consider.

With its separate design—splitting the tweeter and the woofer—this model makes it easier to fine-tune the soundstage and the expression of the mid-to-high frequencies. The tweeter level can be adjusted from 0dB to -3dB, so you can tailor the direction to your preferences—for example, when highs feel too strong in the cabin, or when you want the sound to come from a bit more toward the front.

The input impedance is 3Ω, and the output sound pressure level is 88dB. This is a speaker you’ll want to choose while checking the vehicle-side specifications, including how it will work with a factory navigation system and your existing setup. Even with the same product, how it sounds can vary depending on the installation method, door-side treatment, tweeter orientation, and overall system tuning.

If I were advising you, I wouldn’t decide on the product first alone. I would check your current system and how you listen, then determine the installation approach. If you’re considering replacing the factory speakers, note that the required parts and processing may differ depending on the vehicle model. I think it’s best to organize a reasonable configuration together while looking at the actual car.
