The VAN is the ROOM in REW: Room Eq Wizard!
I knew this was how it was going down, so I went with it. I hoped to get solid replies on the input to my Alpine IVA-W505 HU. I do not want to run RCAs because they tend to be nasty dirty from PC, but I just might have to. Also IDK if I kept the AUX IN RCA connector for the HU. So I tried the 3.5mm LINE OUT on the PC to the 3.5mm in jack on the IVA thats usually used in conjunction with the USB... both go to one end of the iPOD Y-cord, and the other end is the jack to plug into the POD.
I get no audio from the HU from the PC in USB, AUX, or AUX + IN.
The rig: I dismantled the rig I built for the HT and rebuilt it for the VAN. RS meter and Audyssey mic.

I don't think you should be using the usb in. That is meant for ipods because the HU knows how to decode the ipod signal through usb. Your only options are to use the rca inputs on your HU if it doesn't have a 3.5mm jack in. And that aux setting you want to keep on ntsc. That is for video and is a standard in America. Pal is for European applications usually. Also are you using the 3.5 mm jack out on your motherboard? If you are then I would get a decent sound car with preamp outputs that you can connect the rca's to. either that or use a cable that goes from 3.5mm to rca's into the HU.

http://us.store.creative.com/Creative-Sound-Blaster-XFi-Titanium-HD/M/B0041OUA38.htm Pricy but hey sound blaster is the best IMO. That will give you clean sound out through rcas. I use sound blaster fyi.

Oh you have optical in on your HU? You could get this sound card in place of the other one then. http://us.store.creative.com/Creative-Sound-Blaster-XFi-Xtreme-Audio/M/B000W7PNZI.htm Not as good but the specs including the thd is very good. I personally have the titanium xfi in my computer but I do a lot of gaming so.

pulled the dash out...cant pull the deck, I mounted my amps inside the enclosure for the same reason i CAULKED the deck in instead of a plastic 3 screw mounting kit: want my deck, bring a razor, 2 screw drivers, and take your time ;)
The RCA out and RCA in are one connector so i am good! I ran a short set of RCAs to each, before I had a long pair coiled up in the net pouch on the right along with the long ass iPOD cords. USB for audio and control and apparently 3.5mm jack for the video.
While I had her ripped open I got another replacement toggle switch..no more burnt out lights. The new ones dont get as hot, I am assuming me taking them back so many times they rebuilt them better :-P
Ill bring the PC out again later and run some sweeps and see what ive got. I might turn the gains down first though, I raised the 10V and 14V amps to 17V with the other too and its too loud with the sub level set to 0 on some songs. So much work though, pain in the ass matching!

when the subs arent hooked up and I am running a sine wave, they dont actually draw much current at all right? I re-gain matched cuz the shits too loud with the sub level at 0 so all 4 are within .3V now, 27.3V avaerage with the deck at 20 of 35 and sub level 10 of 15. I never play above 20 unless its a really quiet song. that way I can drop all the way to 0 so the subs are very quiet, or crank it to 15 on a quiet song.
It is not an easy task, gain setting, a hair this way... too much, a hair back, too far, so leave that one and try to get the others to match it: good luck.
On top of that, one amp is very hard to move the knob, but when it moves just a tiny bit the voltage changes drastically. The one next to it is easy. The other 2 on the other side move WAY to easy and I dont like it, I dont even turn them... i touch my mini flat had...just touch them.. and they move :(
I started the van and the lights were dim, the motor labored, alternator whining (not squeeling) voltage was way way down! WTF?!?!

Thank you Scott again for giving me so much to do for the last month or however long it has been. I have been building mic stands, running wires, calibrating sound cards, cutting reinforcements to my house (that werent in use not even contacting anymore LOL) down to build walls and using fence latches and foam to seal up and create door ways, boarding up my windows... rewiring my furnace and basement... and now... the VAN! Scott never asked for a thing, just that I share my results with him. That is a fellow DIY guy. Thank you Scott.
As anticipated I have some issues to work out, and my peak burping frequency was as I guessed. First problem, today while re-gain matching... that is a BITCH..I HATE that ****... I noticed a 60Hz hum. I have noticed it before and am still baffled, as this is not home AC power. My 1st sweep I did at volume 1 and PC volume 50% to be safe. Then I tried volume 7 PC 50%, then vol 7 PC 100%. After that I tried 10 and noticed something was WACK. Tried 13 but didnt even make it.. when i turn the HU to 13 I get nasty feedback! It gets louder and louder. When i swept at 13 it was terrible.
I always guessed my cabin would resonate above 40Hz, and I had this feeling that since I am tuned ungodly low...almost verified now at 23.3Hz... I always guessed that since I am tuned to 23Hz I will have a peak at 46-48Hz. I show a peak at 47, so I am guessing when i go burp again, 23Hz will be about a 149dB and 47Hz will be mid-50's.
I cant get good snap shots, even with the sub at 0 ( max is 15) I get almost 105dB only at volume 7 ( I listen between 18 to 21) down low but up high below 60dB.
