I have normal computer speakers for my computer but I would like to add my other sound systhem to it. My other system only has the the black and red wires but I know I can put it on my computer because my friend did it.

If opened up my normal speakers and I realized that they had red and black wires aswell. I would like to know how to put my other speakers on my computer because the current speakers I have aren't very loud and good.

"computer speakers" are normally 'active' which means they have power amplifiers built in. Home music speakers can be but most often are not. They have to be connected to a power amplifier or receiver, which is just a power amplifier, preamplifier, and tuner, all in one box.

If the later case, you must connect your computer to the complete system, not just to the speakers. You need an appropriate cable to go from the computer soundcard, the place you currently have the "computer speakers" connected, to a line input on your music system.

I understand.

I used to have have a receiver and had it connected to my computer but it broke. I connected my speakers to my other receiver but I can't connect my computer or tv to it because theres no inputs for it. I have the wires that go from my computer to the receiver.

I know that I can add my soud system to my computer because my friends has almost the same speakers as me and he did it. It's not going to be as loud though if I do that.

I dont have the money right now to buy a new receiver. Should I try and connect one speaker from my surround sound system to my computer?

You are asking about the value of doing a particular thing. That is completely subjective, no one can decide for you.

Some soundcard do have a very small power amplifier chip intended for headphones, but I would doubt passive speakers used instead would be very satisfactory. Also, attaching passive speaker(s) is likely to degrade the signal to the computer speakers. There is no problem connecting two, or several, line level inputs to a line level output (e.g. computer speakers and receiver attached to the same soundcard output) but passive speakers are a different matter because their impedance is very low relative to the expected load.

You also would not want the speakers attacked to your other system and to the computer at the same time if they don't have a proper interface (i.e. a receiver) in between.

Thanks for all the help.

I am just going to keep the speakers that I have right now on my computer. There actually pretty loud and I arranged the equalizer on my player and it sounds really good.

I might buy a reciver when I have enough money.
