Windows 7: Add 5.1 speakers to 2.1

Add 5.1 speakers to 2.1

Hi, i have 2.1 harman kardon system sound stick 3 and i have 5.1 logitech x540. I have on board 6 audio jacks, i want to add to the 2.1 speakers the 5.1, ive already tried it and it worked, i wanted to know if nothing will happen to the motherboard, if it can stop because of over load. I have the 2.1 speaker connected to the green jack, and if i hook up the 5.1 speakers, than im not using the fronts left and right im just adding the center rear and one more bass. Can i do this without worring that something will happen to my motherboard ?
Thank you.

Your motherboard will output 2VA Max of audio signal on each jack, the number of devices connected will not overload the motherboard but decrease the power available to each device. Are you using splitters?

Im not using anything, i just took the logitech speakers and connected the black jack (rear speakers) and the orange jack (center and sub) and the harman kardon connected to the green jack. That way both of the speaker system works. So can i keep it without worring about anything ? Because the harman kardon has 65 watts and the logitech has 70 watts RMS. so im just want to be sure that the ports will not burn or something.

Not an issue at all, the wattage to the speakers is an isolated circuit between the speakers and their amp (usually built into the sub unit which connects the the mains supply). The 3.5mm output supplies the amp with 2VA max, you could connect any power sytem to each of the outputs with no issue.

You should try the 5.1 system by itself and take the 2.1 system out of the loop.

I think that will cause a conflict.

Even if there is no immediate conflict.......the 5.1 and 2.1 is called a system for a reason. I'd use one or the other.

You wont get true 5.1 surround unless all 6 channel (2 per jack) are connected to the 5.1 system. But if you are simply after volume then carry on the way you are. The main benefit will come from having a second subwoofer,

The 2.1 system obviously has more powerful speakers, as they achieve a similar RMS output with 3 less satellites. I would use the 2.1's for the front channel, and if the 5.1 system does not actively switch inputs to emulate 5.1 I would connect the centre and rear channels to that system but connect the front speakers from the 5.1 to the Rear speaker RCA output, leaving the rear speakers from the 5.1 system redundant. This will give you True 5.1 (5.2 really) with the maximum RMS output available!
