Review: Impressive little amp - I had an old centre speaker that I wanted to make use of in my work shop ... took a gamble and WOW what a super little amp Needed a 12v supply but will up to 24v eventually sound is great no back ground noise and no hiss .. easy set up all instruction are on the seller page . Any one that moans about fitting the cover needs to have a rethink on value for money . 10 quid for an amp this good is worth every penny I added a small active sub using the headphone 3.5 jack for bit more bass Works without issue . Overall really happy with quality of Bluetooth and sound quality
Review: So good, that I had to buy another one... - I bought this so I could stream music from my phone to a pair of old speakers in my shed. Connected it up to a 12V power supply from an old laptop and it just worked straight away. How can something so small and inexpensive just work so well? I've now ordered another one to use in my home office. Highly recommended!

### ⭐⭐⭐⭐⭐ It works, as sceptical as I was.
*by L***M on 26 January 2025*

Used to convert an old Philips centre speaker into a portable bluetooth boombox. Took less than 5 minutes to put together and wire up. Works with anything from 12V up to 24V psu, and even powered it with a portable phone battery and a 5V to 12V boost cable (£7 on here). Excellent value for money.
