【SPC350 Speaker Cable Using PC-Triple C】
You swapped your car speakers, but the change in sound is smaller than you expected. Or you want to bring out a bit more sound body, sheen, and the presence of the vocals. In such cases, it’s worth looking again at the speaker cable.
SPC350 is a speaker cable that uses a PC-Triple C conductor. Designed with the goal of smooth signal transmission, it uses a proprietary continuous forging and drawing extension technology that reduces the conductor’s crystalline grain boundaries and continuously aligns the crystals in the direction the signal flows.
In terms of sound character, it tends to add a pleasing sheen to vocals and instrument sounds while preserving information content. Even with songs you listen to all the time, it helps make vocal contours and overall sonic cohesion easier to hear, and it’s also easier to finish with a natural sound you can enjoy for long periods.
Switching cables won’t necessarily make the sound change dramatically. The result can vary depending on the speaker performance and the amplifier pairing, the processing on the door side, and how the wiring is routed. If it were me, I would use SPC350 in the necessary places while checking the overall balance—including the speakers and amplifier.
With an outer diameter of 7.5 mm, it is thicker than a typical regular cable. Depending on the vehicle, you may need to confirm how the wiring is passed through and how it is secured, so it’s reassuring to plan a reasonable installation method while looking at the actual car.
If you want to enjoy the sound changes properly, or if you’d like to further refine the finish after replacing your speakers, please consult us after confirming your vehicle model and your current system. Let’s not decide based on the cable alone—together, we’ll shape it into great sound, taking into account how you use it and your preferences.
