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.

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)
https://www.ebay.com/itm/273304204472
12V
1A
5-9W (Rating for a 1-meter length strip, I will be cutting it significantly shorter)

Carbon Brushes - (Ordered)
https://www.aliexpress.com/item/32775702269.html?spm=a2g0s.9042311.0.0.109b4c4d2TyILq

Copper slip rings x 2 (Ordered)


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

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,

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 the advice and help everyone's given to me for this project so far!

Thanks
Jacob
