How to convert Home System Speakers to Computer Speakers

[geri710]

Hey guys.
I've been trying to upgrade my computer speakers(Logitech S-150) because the sound is very weak. But since I have a Speaker System(Sharp CP-CP1500) sitting on my living room if there is any possible way that I could only use the speakers on my computer because I am on a tight budget and those speakers have high quality sound.
Here are some pictures of the Speakers.

Not really without an amplifier.

I know that. The speakers are 200W I think plus they have only simple cords as you can see in the picture. So I need a guide on how to convert the cords into a 3.5mm jack or a usb and what amplifier do I need.

You don't convert the speaker wires into 3.5mm.
You connect the speakers to whatever amp you get, and you connect the amp to the PC audio outputs.

Do you still have the Sharp amp that came with those speakers?

The wires of the speakers that you see in picture go behind the Stereo System.

Right.
So then you do an output from the PC audio, into that Sharp stereo.
LINE IN on the stereo.

Is it possible to give me a more detailed explanation ?

What inputs are on the back of the Sharp stereo?

So...
A 3.5mm to RCA cable.
From the output on the back of the PC. Probably the Green port.
On the back of the stereo, the RCA jacks go into that AUX In.
Red/white

A cable like this:

$3 at Walmart or Amazon.

So the PC outputs through the audio output. Just like it does with your current Logitechs.
But instead of going directly to the speakers, it goes to that Sharp receiver.

On the Sharp, select AUX for the audio source.
Done.

 

[geri710]

Belive it or not I have this cable. I'll give it a try right now and let you know if it works

 

[geri710]

Thank you very much my friend. I tried and it worked. But is there any other way to use the speaker without the stereo ?

No, the speakers need to be amplified, and that's what the box does. Without it, they don't make a sound.

 

[geri710]

What if I buy one and attach the wires to it or smth like that?

 

[getochkn]

No. Why would buy an amp, you already have one, and I don't even think you really know what it does. Speakers need power to make sound, bigger the speaker, like those, the more power it need. Your PC can't do it. That amp is made perfectly for it. Another amp wouldn't even work right because of the weird way those speakers work with the unpowered sub's built on them.

You say you're on a budget and can't afford anything, you got it working for free with a wire you had lying around, and you're not happy and want to spend money that you don't have, I don't get it.

 

[geri710]

Hahahaha. I know what an amplifier does. My current speakers are attached to a subwoofer and every time i turn the volume too 100% the speakers turn off. Probably an amplifier wouldnt be as expensive as a new speakers. It's a pain in the ass to turn up the Stereo every time I want to use the speakers. It would be more practical if they were connected to an amplifier.

No.
What you currently have works perfectly. Or at least as good as it will get.

To drive anything larger than headphones or earbuds, something must be plugged into the wall.
Either your previous Logitechs, or this Sharp amp.

You cannot drive those speakers directly from the PC audio output. Will not work. Ever.

The Sharp 'stereo' you have is an amplifier.

So leave the Sharp at 60% volume (or whatever setting), and control the actual sound from the PC.
