Product Overview

DS18 QHL4

Upgrade your vehicle's sound system with DS18’s QHL4. This compact converter is your key to unlocking superior audio quality and seamless integration.

Engineered for those who demand nothing but the best, this 4-channel converter delivers pure, unfiltered sound with seamless integration into any vehicle system, whether OEM or aftermarket. Advanced transformers and cutting-edge noise rejection technology ensure that your audio remains untouched by interference.

Installation is a breeze thanks to its compact, rugged design, complete with a detachable harness and straightforward labeling. Versatility is at its core, effortlessly handling both high-power (up to 100W) and low-power sources, making it the perfect companion for any setup. With built-in speaker simulation, the QHL4 guarantees flawless integration by ensuring your OEM source detects the original speaker load.

The QHL4 doesn’t just stop at superior sound—it’s smart too. The intelligent +12V remote output automatically triggers your amplifiers, with LED indicators for easy monitoring. And with its durable aluminum housing and tear-proof wiring connector, you can trust it’s built to last.

Disclaimer: Ensure your vehicle's electrical system operates at 12V DC with a negative ground.
