My question is simply do you know of any "not-so-expencive" AV Preamp recivers, like this one http://www.outlawaudio.com//products/970.html . but maybe few hundred dollars less expencive.

Well, here's a local tip - check Góši Hirširinn or Partalistinn

It should end up as a nice system AFAIK - I've used Tang Band drivers similar to those that Logitech uses, and they respond very well to good amplification.

Did you also connect pin 13 (GND of amp I presume) to GND of your headphone connector?

OK, after some more testing on my Z-5450 I found out that the subwoofer probably is not muted, because when I don't unmute it, I can't hear anything at all. Also I can hear the amp doing some noise when I turn it on or off.

Here is an updated pin layout for the Z-5450 (for subwoofer audio only):
pin 2 <--- line out signal (audio for subwoofer)
pin 6 <--- line out GND (unmute)
pin 7 <--- line out GND (turns amp on)
pin 13 <--- line out GND (signal GND)

So if you have ANY idea why the subwoofer is so really quiet, please tell me. Thank you very much!

Can anyone make more "inside" photos ? Very interesting to see that.

Hi Guys,

Ive been following this guide to pretty much recrate what Baumm did. The only problem is that i have no pin 6. Since im in australia things seem to be quite different (including the board) but pins such as 13/14/15 do match up.

So at the moment in have 7/8/13 connected to the sleeve of an RCA and the 2 connected to the middle of the RCA but the amp/sub will not power on.

Im at a loss looking for what to use since i dont have a pin 6 on my board. I have tested this via a Multimeter(VOM) and tested for continuity only to find theres nothing there.

Any help would be apprecitated.

Hey guys, i am a total novice at these things, being only 17, but ive analyzed this thread pretty well (i think).

So i have a couple things to ask.

#1: Could you do this with a stereo reciever? (JVC RX-6020V) It has a sub out..

#2: When soddering the wires, are you soddering RCA wire (Center; sleeve) to S-VGA wire (pin wires 2; 6,7,8 and 13) or to the actual inside of the sub (on the chip)?

Any help would be GREATLY appreciated as ive been trying to figure out how to hook this up without the stupid little control pod (which goes for about 200 dollars on ebay...) for around 6 months. I will be following this thread closely, as it is the only one of its kind on the net.

Thank you so much for all your posts, im so much closer to having a working set of wicked speakers. Now all i need is these two questions answered and ill be set!
