Wuzhi Audio Mini Bluetooth Amplifier 2 x 50w channels 9v to 24v Bluetooth Amplifier Board K-502

This is a review of the Wuzhi Audio mini bluetooth amplifier, featuring 2 50w channels and capable on a voltage range of 9v to 24v.

I test this amplifier using a 12v battery with Pioneer TS-G1010F speakers and music provided by Neffex on youtube

I will be installing this mini bluetooth amplifier into one of our powerwheels kids ride on toy cars along with the Pioneer speakers.

00:11 - 03:37 Assembly & Review Part 1
03:38 - 04:45 Sound Test
04:46 - 06:54 Review Part 2
06:55 - 07:17 Outro Song (Higher Tones)

I should add that I attempted to run this off a USB power bank as it does state it can run on 5v, it was not that impressive, 9v is the minimum voltage I recommend for this amplifier.

This amp may be referred to as ZK-502 board.

Thanks for the awesome video, keep them coming :)

Thanks I’m gonna use this for my 1960 car without buying a $400 retro radio.

[leefiles]

How much energy does it use at idle (when there is no sound)?? Please use your own situation.

[thefirefightingghostbuster]

thank you for this review! This is the first one i found with it connected to a battery.
My plan for this unit, is to use it in a CHOSTBUSTERS proton pack. I know not all batteries are the same, but would you have a rough idea how long this would last before requiring a recharge?

[ideaboxes]

Great video. Does this device come with a power adapter and what is voltage like ?

[gfpossa]

It supports 2 speakers jbl 3.5w508? Which voltage needed? 12v 2.2a is ok?

[wollyknowsit]

No longer works after recent Windows 10 update in August 2024. Cannot uninstall properly either. I uninstalled in Device Manager and there is no reference in Registry but it still appears in Bluetooth Menu as 'paired' but cannot connect. Not recommende.

[privatenerd]

People are using this to maximize voltage of electricity in walls or lights and use as direct energy attacks

[wuyu-lin]

Thanks for this video, can i have more information of this Bluetooth Amplifier about hissing or any noise?

[ronw]

Hi, can you tell the name of the ic chip they use as the amplifier? is it getting warm?
thank you

[adamtencza]

Can you plug audio in with 3.5mm audio jack?

[wijiadi]

any difference in sound quality between Aux and bluetooth?

[johnbellini]

cannot be bridged to run 2 of them in mono config?

[danieleduardo]

el amplificador es de 50w rms dual ? o es pmpo?

[jacquesduplessis]

I suppose they don't assemble it due to import tax reasons, because it's not really a project if it takes 2 minutes to build😁😁

[moisesbuenfil]

Alguien más tiene el problemita que cuando prende el ampli, bota/se cae su internet wifi??
