This service allows you to bring in your own separate 3-way front speakers for replacement.
This service is only available for vehicles with factory 3-way configurations or for those who choose to install 3-way speakers.

We clearly distinguish between the roles of the woofer, midrange, and tweeter, and consider the vehicle structure, interior design, and the specifications of your speakers before determining the installation location and wiring configuration.
Because 3-way systems are significantly affected by installation conditions, we conduct a preliminary check to determine whether installation is possible and the work involved.

For 3-way systems, those who choose to purchase their speakers from us will receive preferential treatment in terms of both installation content and price.
We do not perform unreasonable retrofitting or simple installations; instead, we install systems that are easy to expand into, such as adding an amplifier or upgrading the system in the future.
