【Hiace-Specific UD-K5311 (16cm/17cm) Inner Baffle】

When installing speakers in a Hiace door, it’s important not only to mount the speaker itself, but also to create a solid foundation to secure it properly.

If the strength of the door sheet metal is insufficient, the speaker’s vibrations are more likely to cause unwanted resonance and rattling noises. Also, if sound that wraps around from the rear of the speaker interferes, the overall sound may become less cohesive, and you may not fully take advantage of the benefits of the replacement speakers.

UD-K5311 (16cm/17cm) is a dedicated inner baffle designed to install 16cm/17cm speakers in the Hiace doors. The rigid MDF baffle stabilizes and securely fixes the speaker, while the included sound-deadening cushion helps reduce the effects of sound coming around from behind the speaker.

Not only does it help you install the speaker, but by building a proper foundation on the door side, the sound’s attack and the cohesion of the bass can change. For those who want vocals to be a little easier to listen to, or for those who want to clearly feel the difference by replacing the factory speakers, this is a part worth considering together with the speaker.

Even with the same speaker, the final results vary depending on how the baffle is fixed, how the door is treated, and the adjustments made after installation. We can also think together about how far the work should go while considering compatibility with the Hiace’s factory system and the speakers you plan to install—so if you’d like to enjoy the changes in sound, feel free to contact us.
