Amplifiers for Speakers

Revolution

My brothers has old CD Player Samsung MAX VS720.
Unfortunately the CD Played not working anymore but the two speakers are working.
I need a cheap easy solution to run those speakers for mobile music, FM radio, SD card , USB Drive or may be for PC use.
Is it possible ? Do I need some kind of Amplifiers ?
At least I want to connect both speakers with my mobile to play music.
I don't want to spend tons of money on those speakers either.

This one has BT+FM+SD+USB function with remote at 1399/-

this one has BT only at 1299

Screw them in the original amp box of samsung or buy a cheap acrylic box and drill as necessary.

One more thing, you will need to take care of power supply, usually cd/dvd player use different pcb for psu unit, check if yours too has a separate one and check its rating, if it is 12-24 volt then use that same else buy a adopter like this one mentioned below


or use any old laptop charger

Dont use this if it is a 2.1 subwoofer + 2 channel configuration, for that you need something like this:

Actually for some reason (maybe chip shortage) price of amplifier chips are increasing. These boards used to be 600-700 in 2019 when i bought one, but due to increase in raw chip value, this us quite expected.

if the problem in your stereo is related to to tuner and not related to amplifier and power supply, you can reuse that with just a cheap A$$ 3.5 to pigtail wire.

maybe check what is the fault?

Avoid such amplifiers, they have not mentioned the chip used, class used and using definitely a fake branding claiming to be 5000 watt. These things don't last and end up frying speaker. There is a high chance the product maybe locally made of low quality components.

Always check for chip used and the class of amp.

I don't have any knowledge in electronics.
Even if I buy similar naked amplifier board I will not able to connect it to power adaptor or Speakers and put the board into any custom made enclosure. I do have a power adaptor of trimmer. Not sure how much volt it produces.

Can ypu attatch the pic of speaker Where the power and impedence like information is visible as it is not mentioned in the manual. I may have a cheaper alternative for you.

This manual don't have info ?
I need to ask my brother then.
If there is any written info on it.
It has no info about the speakers used, there type frequency response, power etc. it only tells that it has 70 watt 6ohm amp in it, so depending on speakers, I need to find a amp
