Problem with MP3 module

Hey,

I'm making a small nightstand as a fun project for my vacation. When I was browsing
some sites with ideas I came across the idea to make a mp3 in the nightstand. So I've been
browsing the internet for some modules and I came across two modules which fit my demand:

**broken link removed**
**broken link removed**

The first one looks quite good and is very simple seen as the cables are included and the only question
I have with the first one is if the wires on the back ( the red and black ) are for speakers?

The second looks also quite good and is fairly cheap. The problem is ... I have no idea which
cables i need and which speakers ( the problem of which speakers is also for the first one )

So for those who know about this:
Which speakers do I need?
What cables do I need?
And do you have any suggestions or maybe a better option

Thanks for reading

Cheap junk without a detailed datasheet requires simple guessing. Maybe you will guess wrongly. Maybe they will sound awful or will burn out soon.

The first one has a built-in power amplifier to drive speakers. It is probably stereo but maybe it has 4 channels like car radios have. Car amplifiers drive 4 ohm speakers.
Nobody knows what the red and black wires are for. Hopefully it comes with instructions in Engrish.

The second one has a built-in FM tuner but it says " Integrative amplifier" whatever that means. It is too small to have a built-in amplifier that is needed.

So... which speakers should i get and where can i hoook them up?
Can you maybe give a link to the speakers?

Some people are tone deaf and NEVER listen to music so cheap little speakers are fine for them.
Other people want the sound to be real and live so they need speakers that play deep low frequencies, medium frequencies and very high audio frequencies at the same level. They are not cheap.

A speaker needs an enclosure that is properly designed for its spec's. You didn't say if you want to build the enclosures yourself but half-decent speaker drivers have detailed datasheets with plans for a recommended enclosure.

I still have the second speaker I built the enclosure for. It is 50 years old, is still used every day and sounds great. The manufacturer of the speaker drivers (woofer and tweeter) showed plans for the enclosure.

Since this is, apparently, something of an experiment for you, I'd go with your second listed player. Less complex (no radio) and more easily accessed input/outputs AND they're at the back of the rig.

Remotes are nice but easily lost, so in that event, this player has the normal control buttons for an MP3 and an LED readout (the other did not: no play/pause, no readout).

You'll have to come up with some miniature connectors which are not always easy to find. I get most of mine from scrapping old VCRs, DVDs and the like. You can use female, pin type, single wire push-on jumpers instead if need be. All Input/Output pins are marked as to function.

My experience with little buggers of this sort is that the on-board amp will handle most low power, cheap speakers (2" to 3" types). Sound quality roughly equivalent to a bedside clock radio.

And again, this is for some vacation amusement, right? For the price, buy 2 in case you blow one up .

Also, it says it takes a 12DC working voltage but the device itself uses a built-in, regulated 5VDC (USB level), so anything in between, say, 6 and 12VDC will work for your external power. Get a wall wart rated within that voltage range and with, say, 400-500mA capacity (the MP3 decoder itself only draws about 50 to 100mA, and that only when its playing).
