I'm currently running an inverter (until I can save for the Arise 865) and a stereo RF transmitter - poor combo I know.
Is there any way to shield the inverter or rig a temporary (cheap) solution get the sound card output to the head unit, or am I SOL?
Put the inverter in a metal case and ground it. Replace all inverter power cables with shielded units and ground to the same place you grounded the case. Also, use a ground loop isolator to help get rid of hum.
Thanks! I'll give that a shot...
Ground loop isolators you have to be careful with. They color the sound. Some just a fraction, others more. The proper thing to do is instead ground the p/s, PC, stereo, EQ, amps, etc., to a common ground point. Just grounding to the car body should work but with today's cars you have to be sure your grounding to a part that's got good contact with the frame of the vehicle. With my setup, because of a need for power exclusive from the stereo system, I ran 8AWG to the back of the truck and used distribution block from a marine parts store. Then I figured to do the same for the stereo. Now I hook everything up I need to the distro block. ZERO noise whatsoever in the system.
Hi
I have a similar problem but instead of a hum I get a crackly signal.
The ground loop isolator where does it connect to and what brand do you recommend.
The ones I have seen for sale in the US connect as a pass through with RCA connectors and look like they are using a set of inductors this was the Boss B-25N.
I am from the other side of the world (Aus) so don't have the same sources available to me and want to get the correct one the first time.
Where do you get, or how do you make shielded power cables.
Thanks in advance
BTW I have found a car cassette system that has a jack on the front marked CD drive. This could probabally take a straight plug in from your MP3 player. It's $110 Aus dollars that makes it approx $52 US check it out

No I don't get a comission.
I may install one as a last resort mainly because my car doesn't like casette players the one that is in it at the moment is the third that has been installed. They just stop being able to play tapes !
Crackly signals usually mean a bad connection somewhere in the audio circuit. If you are using 1/8" or 1/4" phone plugs, that is probably your problem.
About shielding the power cables, what if you ran the cables through some metal conduit which would run straight into your metal box and be grounded with the box?
If you're running an inverter and can't get rid of the noise you can try running the system with the computer power supply outside the computer case. Like have all the units seperate, power inverter, power supply and computer.
That's what I did and I have absolutely no noise without a groundloop isolators and all that jazz.
