GotSQ?

So i followed an online tutorial -How to hook up a car subwoofer to your computer or home theater system | eHow.com
To allow someone to connect a sub and car amp up to their computer.

These are the supplies im using:
Soundstream di 175.1
Pioneer TS-W256C 350 rms sub
Antec Earthwatts power supply.

My problem is, the sub wont go louder than my dinky little 6" sub that gets 30 watts rms.
Hope to hear from you!
There is a picture of how its wired here:

probably your power supply is way to small, need as least a 20-30 amp and it could be your x-over is set wrong or the computer might not be sending full bandwidth to the preout section of the amp.

GotSQ?

The amp doesnt have a crossover setting :/
full bandwith to the preout?
Any solutions?

On XP its:

Control Panel>sounds & Audio devices>on the volume tab there is a speaker settings section. Click on advanced and set to proper speaker installation.

Im running vista, but ill do some research into it. On the side of the psu it says 17 amps, that should be enough for 100 watts?
