【AT-RS180P + Speaker Cable Routing & Installation｜Installation that refines the sound pathways for under-seat DSP and amplifier systems】

When combining speaker replacement with DSP and an external amplifier, one thing that’s surprisingly easy to overlook is the** routing of the speaker cables**.
While it’s common to focus on the performance of the speaker unit and the amplifier, the cable route is an important path for delivering the music signal from the amplifier to the speakers. How well this is done affects not only the cohesiveness of the sound, but also how easily you can upgrade the system in the future.

AT-RS180P is a model that, among Audio-Technica’s speaker cable lineup, makes it easier to balance sound thickness with fine, detailed expression.
It uses a triple-hybrid conductor that combines PC-TripleC, PCUHD, and OFC. This helps provide solid stability in the mid-to-low range while also making it easier to handle treble reverberation and subtle nuances.

In particular, when installing a DSP amplifier or external amplifier under the seat and driving the speakers in a front 2-WAY + rear configuration or a front 3-WAY configuration, the routing of the speaker cables is crucial.
It’s not just about running the cable. By also considering moving parts on the vehicle side, interior disassembly/reassembly, the impact of noise, and how to bundle it so it can be inspected later, the finish in areas you can’t easily see will be dramatically better.

This is a section that is hardly visible after everything is completed, but this is exactly where I would want to take careful, deliberate steps.
A setup that leverages the factory speaker wiring has its merits, but if you’re also building a system with a DSP and an external amplifier, there’s value in revisiting the cables—because it helps deliver the amplifier’s power to the speakers more directly.

As for the sound impression, it’s related to things like low-end contour, the core of the vocals, the reverberation of the sound, and the connection between left and right.
Of course, simply swapping cables won’t “complete” the sound by itself. It’s important to shape the sound so you can enjoy it comfortably in the cabin, including the speakers, amplifier, DSP, the door-side installation, and the final sound tuning.

At LOGON, we perform the installation while checking details such as where to route the cables, how to bundle them at the appropriate lengths, and how not to place stress on specific parts—based on the vehicle model and system configuration.
Wiring is an operation that typically isn’t very noticeable, but if you do this cleanly, it improves not only the sound, but also future maintenance and how easy it is to change the system later.

AT-RS180P + Speaker Cable Routing & Installation is for people who don’t want to stop at just replacing the speakers, but want to drive the front speakers firmly using a DSP amplifier and/or an external amplifier.
How much you need for your current system depends on the vehicle, speaker configuration, where the amplifier will be installed, and future expandability. So rather than deciding with the cables alone, it’s better to think together while looking at the overall balance.
