Review: Best amplifier for 100 Watts subwoofer - Powerful output and stylish design.
Review: Shakes the Shaker ! - Bought this to power the Dayton Audio BST-2, i keep the volume on full. Im not sure why ppl have multiple shakers. The shaker has enough oomph with this amp. Screw holes would have been a plus. The device itself is robust, the volume button doubles up as power on. could have been separate.

A: 3.5.   I run rca into a 3.5 from my radio

I use this as the speaker cable and before shutting off the amplifier, I flip the switch on the speaker cable, disconnecting the speaker from the amp. It works perfectly.

**Q: will this work with an input from a preamp?**
A: Not sure. I used input from a receiver and that worked.

### ⭐⭐⭐ Review
*by S***E on 28 March 2025*

Não liguei ainda o amplificador porque ele veio sem o AC 19V que é uma dificuldade encontrar . Acredito q isso não estava ‘ avisado ‘ . No mínimo o vendedor deveria deixar mais explícito como também aonde encontrar um AC correto e compatível.
