How to Add Rex Volume Increase in Your Own Chrome
Ever hit 100% volume on a laptop and it still isn't loud enough? That's exactly what Rex Volume Increase fixes. It's a free Chrome extension by Team Cipher that lets you boost any tab's audio up to 600%, with a built-in limiter so it never distorts, bass/treble controls, a Voice Enhancer for calls, and settings that are automatically remembered for every website you visit.
It runs entirely inside your browser — no sign-up, no server, no data ever leaves your device. Just open the popup, drag the slider, and the tab gets louder instantly.
Since the extension isn't on the Chrome Web Store yet, here's how to add it manually — it only takes about a minute.
