there is a thing u get so you can plug two pairs of headphones into the same socket. e.g sharin the same cd player. if you can find one of those, just plug the left and right subs into that, and plug it into your sub port on your computer,

Duties are not performed for duty's sake, but because their neglect would make the man uncomfortable. A man performs but one duty - the duty of contenting his spirit, the duty of making himself agreeable to himself.

Wattage has nothing to do with it.
By adding speakers to an amplifier you change the impedence(or load) on the amplifier. Consequently the amplifier will work harder to drive those speakers, get hot, and then fail.

I work in the repair business. Don't waste your time.

Speakers don't consume watts. They have a maximum wattage rating. It refer to how much power in watts you can apply to them safely.

If you connect 4- 8ohm speakers in parallel to the same source the impedence will be much too low and you will overload the amplifier.

4 x 8 ohms connected in parallel would be equal to or less than the original 8 ohms!

8 ohm speakers do not have a resistance of 8 ohms. They are 8 ohms impedance.

If you connect 4x8 ohms in parallel you get something close to 2 ohms.
If you connect 4x8 ohms in series you get close to 32 ohms.

2 ohms is closer to a short circuit than 8 ohms. Therefore more load on an amplifier.

Most home audio systems should not be run at or less than 4 ohms.


Ok to be precise, they don't consume watts, they consume amps which are converted to watts based on resistance. That's why better ones are vented or fluid cooled, to deal with the watts(heat energy) produced.

About speaker wattage: It's not about how much energy they produce but the maximum power input in watts you can apply before they overheat.

8 ohm speakers will not fry an automotive amp. It is just less efficient.

And you can run some automotive amps at 2 ohms. (usually good quality amps) as automotive standard is 4 ohms... compared to home systems of 8 ohms. Running a high quality automotive amp at 2 ohms (if it can handle it) will deliver more power than the same amp at 4 ohms.

The lower the ohms the higher the output an amp will produce (within reason) because of the higher load. (back to ohms law) :)

OMG high school physics all over again. Your killing me.

My solution:
Buy another soundcard :)
