09 xB Power Inverter Causing Sound Problem..HELP Please
Hey Everyone,
I've had my 09 xB going on 3 weeks now, It's been great so far.
I added a 10' sub & amp no problem with it.
I have a Asus EEE (mini pc) and an external Hard Drive for music and video.
(Both can run on battery power for awhile)
Anyway I have a power inverter, ran the power straight to the battery.
The problem is when I turn the inverter on & use the Aux for sound
there is distortion coming from the speakers.
I've bought a few other Inverters from $40-$75 same problem.
Can Anyone help solve this problem?
Thanks for your Time!

But the inverter is powered directly to a fused cable to the battery +, correct?
Are you getting more of an alternator whine, or straight up overdriven distortion?
Aaaand last, but not least, are you getting this distortion to teh OEM speakers, or just the subwoofer you added?

But it doesn't make that sound when the inverter isn't connected to the devices, correct?
Weeeeeeird.
This is boggling my brain banana for sure. Only thing I can see is that the inverter is producing some kind of audible distortion.

You are correct when the inverter is off All is Good.
I took it to the shop where I got the amp put in,
The installer said the 1st inverter was no good.
I bought 2 different 1's 2day the problem remains.

Four things come to mind:
1. Check you ground/find a better grounding point.
2. Lower the master volume on the Eee and/or check for new audio drivers.
3. Buy a DC-DC power supply (cheap inverters don't provide clean power).
4. Ground loop isolator

The only thing I can think of is that the inverter is introducing electrical noise. Maybe the shop you mentioned can put their oscilloscope (that they should have for setting audio gains) to your electrical system and the inverter and playing around with things, ie. turning the inverter on/off, hooking it up directly to the battery terminals, try on a different car etc. If it is the inverter... then I guess you'll need some sort of choke coil or a new (better) inverter.
Good luck, electrical noise is never fun.

Yea if it sounds like distortion then i think its the RCA's or PC.
The inverter would induce alternator whine or such..not distortation..
Are you sure the PC is working right?
Lower the volume on the PC..
I have a CarPC and its great..

Thanks for your help guys. I think it is alternator whine because when the pc is running on it's battery there's no whine. With that said what should I do about the alternator? Get a better battery?
