Ok, computer speaker/amplifier problem, PLEASE HELP

[i_D_r]

K it's a bit long story so bear with me..

 

 

 

 

 

 

 

Basically when I bought my new computer it came with a set of sony vaio speakers, and I went to radioshack recently and bought a Y cable so I could set up my old set and my new set of speakers at the same time. The guy warned me that the speakers better be amplified off their own power (which they are) or else I could damage my sound card. After about a week of no problems I notice my sound basically quiets down temporarily and then boosts back up to the said volume. After some investigating and unhooking the y cable set up, I realize my old set of speakers (which are plugged into my subwoofer --> which is plugged into the computer/power outlet) are the thing cause this weird problem. I plugged my sony vaios in on their own and noticed no difference in sound volumes like it was doing. So thankfully, it's not my sound card (i think) Now, the old speakers that are doing this do it in sync, or in other words, both dwindle the volume temporarily at the same time. This leads me to believe either my amplifier or handhold volume for the speaker set has some kind of problem.

 

 

 

 

 

 

 

I have no idea really what the hell it is, but I'm pretty sure the Y cable set up messed my old (good) speakers up pretty bad.

I'm not sure exactly what's wrong but I find it very hard to believe that underpowering your speakers can damage them or the soundcard. I'm pretty sure the guy was wrong, but I could be wrong. Since the set that doesn't work is amped this shouldn't be a problem anyway.

 

 

 

Have you tried just plugging in the speakers that don't work correctly?

 

 

 

Also, have you tried them with another computer or a cd player or something?

Yes, I plugged them in without the 'y cable' and it's still the same random volumizing stuff. I actually noticed it's gotten worse.

Underpowering passive speakers will not damage them.

 

 

 

 

 

 

 

Running a power amp of the socket int the back of a PC is not a good idea. That socket should be marked low power items only.

 

 

 

 

 

 

 

Cross linking 2 sets of separately powered speakers without an active crossover is a very bad idea. (the more powerful amplifier is very likely to back feed into and burnout the weaker one).

 

 

 

 

 

 

 

It overpowering speakers damages them, symptoms can be variable volume output.
