Even at its launch, the palm-sized QS-TWO caused a sensation – and no wonder: Never before had such a compact amplifier combined impressive power and sound quality at this top level. The QS-TWO quickly gained a loyal following, especially among classic and vintage car enthusiasts who place particular value on discreet installation. From this community came the desire for even more convenience: "Please integrate Bluetooth into this little powerhouse," was the unanimous request. What initially seemed impossible is now a reality.

 

The new QS-TWO-BT is equipped with state-of-the-art Bluetooth® technology – naturally without compromising on size or performance. And best of all: Thanks to Bluetooth 5.0, you can enjoy wireless music in the highest quality. So small, yet so powerful: With its ultra-compact dimensions of just 90 x 70 x 35 mm, the QS-TWO fits almost anywhere – even behind the car radio in the tightest dashboards. Anyone who has experienced the sonic power packed into this tiny device will never want to be without it again.

 

A true price-winner – EISA AWARD for the QS-TWO-BT:

The international audio community has recognized this amplifier as a true innovation with the exclusive EISA trophy: In the In-Car Streaming Amplifier category for 2025–2026, the Bluetooth version was awarded the coveted EISA AWARD as the best product. A clear signal: Here, innovation meets unparalleled performance.

 

With 2 × 95 watts RMS at 2 ohms, the Bluetooth version also offers more than enough power reserves and effortlessly drives speaker systems with 4, 3, or 2 ohms. It remains stable and controlled even under demanding loads. The adjustable Bluetooth gain via jumper (-3 / 0 / +3 dB) ensures precise tuning and adjustment of the Bluetooth® function, allowing you to optimally adapt the volume to the respective source. The QS-TWO-BT also sets new standards in sound quality: With a bandwidth of up to 60,000 Hz and a sensationally low total harmonic distortion of <0.005% (THD+N @ 5W), it delivers detailed and precise reproduction. This makes it ideally suited for HD audio without compromising sound quality.

 

For those seeking particularly convenient installation, the QS-TWO-BT-ISO variant with a pre-assembled ISO wiring harness is the perfect choice. The key advantage: If you have a car radio with an ISO connector, you can simply connect the amplifier directly behind the radio – without any additional power supply or cumbersome cable routing across the vehicle. This is made possible by its efficiency of over 90%, which allows for such a compact design. Thanks to RCA and high-level inputs with EPS®, the QS-TWO is also compatible with virtually any factory or aftermarket radio.
