Suggest 2.1 amp

[EugeneF]

I need amplifier, ready made 2.1 so less work for me.

I came across these two amps:

NEW TPA3116 50W+50W+100W 2.1 HIFI digital power amplifier HIFI beyond TPA3123 TDA2030 LM1875-in Amplifier from Electronics on Aliexpress.com | Alibaba Group

TPA3116 100W+50W+50W Subwoofer 2.1 Amplifier Car Amplifier Class D Power Amplifier Finished In Box-in Amplifier from Electronics on Aliexpress.com | Alibaba Group

Are they the same? Which one is better and are there any other options available?

What power would you recommended:

Audiophile Quality DC 24V2A Switching Power Adapter PSU | eBay

or

Yuan Jing Audio - ON SALE! - AC DC Adapter [Universal Switching Mode Power Supply SMPS] [ 24V / 5A ] - $25.33

Hi,

They are similar, not the same, no idea about differences.

Theoretically you want a 24V 10A supply.

Pragmatically forget the 50W+50W+100W as
sheer fantasy, and noting one is labelled 18 DC,
use a high current laptop power supply, 18.5 -19.5V.

They are not difficult to find used, you want 5A+.

rgds, sreten.
