【Log On’s Basic Menu: OEM-Position Replacement Woofer + New Separate Amplifier|Refining Bass Quality】

Want to keep the original look and usability, while getting the bass dialed in properly.
That’s exactly what the combination of an OEM-position replacement woofer + installing a separate amplifier is for.

Because this type fits the woofer into the factory position, it’s easy to rethink the bass thickness and definition without dramatically changing the feel inside the cabin.
By adding a separate amplifier here, the bass can come together more evenly—so you’ll notice not only more drive across the whole track, but also better overall cohesion in the sound.
It’s not just “more bass”; the strength of this menu is that you can steer toward bass that’s less muddy and easier to listen to.

The stock setup is a little underwhelming, but you’re not considering a major system overhaul.
This is a great fit for that kind of usage, and even on your daily commute or usual drives, the impression of your go-to songs will gradually change.
Since it’s easier to shape bass that won’t get in the way of vocals and other instruments, it’s also a combination that you can recommend to people who want to enjoy the entire music experience comfortably.

At Log On, we guide you by looking at compatibility with your vehicle, the connection with the OEM audio, and how cohesive the sound is after installation.
Even with the same woofer, the final result can vary quite a bit depending on how it’s installed and how the amplifier is matched—so the value of consulting a specialty shop is that you can discuss those details too.
If you’re thinking, “I want to add bass, but I don’t want it to feel excessive,” it’s easiest to move forward by first organizing the direction that fits your specific vehicle together.

Because the required configuration and installation conditions vary by vehicle model, we’ll recommend the optimal method after confirming on the actual car.
If you’d like to take bass quality up another level, feel free to consult us.
