Hi,

I'm creating a turntable with lights and music (attached pic for current progress)
I'm hoping for some general electronic component compatibility advice as I'm a novice and am uncertain what components will work in the same circuit.
Determining a suitable sound amplifier and volume adjustment dial is where I'm most unsure.
My intent is to have a single 3.5minute song that will play on repeat when power is turned on, but I'm unsure what type of sound amplifier will be compatible with the following specifications:

Based on advice from another party I intend to power the project with a 3A 12V wall adapter.

The current components I plan to use are as follows:
Motor
https://www.robotshop.com/en/12v-6rpm-reversible-high-torque-worm-gear-dc-motor.html
6RPM
12V
Rated 0.5A
Stall 1.3A
No Wattage info

LED's - (Ordered)

12V
1A
5-9W (Rating for a 1-meter length strip, I will be cutting it significantly shorter)

Carbon Brushes - (Ordered)

Copper slip rings x 2 (Ordered)

These are a current set of speakers I had hoped to use 4 of them in total, with the sound amplifier I have below, but this may not be compatible.

Speakers
https://www.amazon.ca/dp/B01LYHFS1P...uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl
x4 or x6
3W
4 Ohms
Dia 40mm

Sound Amplifier
https://www.aliexpress.com/item/400...store_pc_allProduct.8148356.15.29751dfb8mW6l7
9 - 40V DC
Output power:4ohm 3W
Dim - 40mm x 40mm
Quiescent current:20mA

These are essentially all of the electrical components I'm trying to use in my system, there shouldn't be any other components other than switches and dials. If any of these components seem incompatible please can you advise me on any alternatives?

I really appreciate any advice and help anyone's able to give

Thanks
Jacob

P.S. I'm wondering is it possible to connect a USB/MicroSD card containing an MP3 file to the sound amplifier board and after wiring the speakers and connecting the power and volume controller dial, would the music simply play as soon as power was turned on? My end goal is for the music to start playing when the motor and LED's are activated (all via the same power button), with the option to turn down the volume of the music via a dial control adjacent to the power button
