Hertz HRC 02 重低音遠端擴大機音量控制 (適用於 Cento Dieci)

Installed this in my car last weekend and the difference in control is night and day. I can finally adjust the sub level on the fly without digging through menus, and the -20 to +6 dB range covers everything from subtle lows to punchy bass.

The -20/+6 dB range is perfect for taming heavy bass on jazz nights and cranking it for hip-hop without touching the head unit. Took me under ten minutes to wire in, and the knob has a solid, click-free feel that makes fine adjustments a breeze.

The -20/+6 dB range is exactly what I needed to dial in bass for hip-hop without blowing out jazz vocals. Knob feels solid and turns smoothly, and the install was straightforward with my Cento Dieci setup. Honestly, it’s the best volume adjuster I’ve owned for fine-tuning a sub on the fly.
