just use a relay as the guy said above. wire to ignition.
Or if you want to control it manually, like I do (sometimes I don't want it on when I am driving), just add a toggle switch in line with the +12V.
OK guys it's FINALLY done!!!!!!!:peace:
Got my car back from Traffic Jamz in Encino on Saturday. Got the H701 in there and my PC connected to it via Toslink. Stuck some Hertz HSK-165s in there as well as an Audigy SRX-5 5 channel amp. Unfortunately no sub what so ever believe it or not....couldn't afford one :(
Sounds VERY good so far! But there is one minor quibble, and I'm hoping Jason, either you or Red can explain it. There is a type of "buzzing" sound, as well as a "tweeeeen" or high pitch kinda "tingy/beep-y-like" noise. It's not alternator whine, although it only happens when I actually start the car. It's something else coming through the speakers...in fact it seems to be coming only though the passenger side speakers.
Do any of you guys know what is causing this? Could it be from the connections between the H701 and the Audison amp? I am using VERY good 4ft RCAs between the two, and as mentioned above, only a single TosLink digital connection between the PC and the H701.
There are also two USB extention cables running from the PC in the trunk to the front part of the back seats, but I doubt that has anything to do with it.
You will need to check how everything is run...this is one of the big downsides to having someone else do your install.
What RCAs are you using...VERY good doesn't tell me very much. Some people consider the base line Monster cable to be a VERY good cable...
Are your RCAs run next to any power or ground wires? Using an optical connection should theoretically mean the PC isn't the culpret...unless the PC is introducing it into the audio stream and then the optical cable is transmitting it.
I just finished installing my system, including the PXA-H701 and DVA-9861 head unit. The sound is fantastic. I am a little disappointed, however, because it seems the DVA-9861 cannot select between the three optical inputs. After reading the PXA-H701 manual, I have come to the conclusion that only the RUX-C701 is able to do this:
"Only when using the control unit sold separately"
The main reason I went with this head unit is because I thought I would be able to select between all three optical inputs. Does anybody know of a way to do this?
They are Reference MKIII...the very thick kind with gold plated and sheilded tips.
I'm not sure...I will ask the installer tomorrow.Quote:

Yeah, the CarPC is not the culprit. I turn it off and the sound is still there....but only while the engine is actually running. I remember reading something from Jason a few pages back regarding some sort of ground noise being caused by his H701, so maby that has something to do with it. I can say that it's definitely coming *ONLY* from the front mids and tweets. I don't hear it through any other speakers.Quote:

I have the Alpine W200 Multimedia unit which seems to control almost everything the RUX controller does, but I have seen a input select option. It may be a RUX option only.
Jason since I got you here, and since I just got my H701, can you quickly tell me if there's an easy simple way to give the rear speakers a bit more fill, and make 'em juuuust a notch louder?
You probably read my post where I'm running into noise on the front channels...which I still am...it's just a known issue with some of hte 701 processors unfortunately.
