That was totally it! It now works perfectly after I spliced it into the orange accessory wire in the ignition harness!
From my readings on this card I've learn that it requires a separate power supply using a 4-pin molex normally used for HDDs and CDROMs.
Perhaps the M2-ATX simply doesn't cut it power-wise for this soundcard?
I know that its a rather heavy consumer on electricity when compared to other products... Especially the new Essence STX with its crazy on-board AMPs...
The Xonar D2 doesn't have a power connector for it it pulls power from the pci connector.
My car has is wired like this
Batt------4ga wire------Distrib block--------Amp power line and M2 12+
Amp Gnd line and M2 Gnd------------Distrib block----------Car chassis
Car IGN wire--------diode->|--------M2 IGN
I believe that it is the White IGN line i am hooked into. And the Orange wire is my dimmer line.
I have a new Opus 360V on order hoping that will make my Xonar work and fix this problem.
edit: fixed the text art
Ya i just got an OPUS DCX6.360 from UPS today hooked it up and all of my electrical problems went away.... but created a new problem
the opus is about 2ce the width and about an inch longer in length. how does everyone else have this mounted in a case. or do you have an external case for it?
Good to hear...
I just have mine mounted on the side of my MDF 'case'...can't really see it here, but it's below the top-right fan...
