Power Supply / Sound issue.
I have my mp3 box built and connected to my car stereo. The current problem is that when the mp3box is connected to the car i get a nasty buzz from my speakers. However if i get an extension cord from my house and test it works (well works without a buzz the sound quality is still a little "hollow" but not bareable). Now I am trying to figure out whats wrong, I have grounded my powersupply by connecting a wire to the outside of the ps box. Here is some more info that might help someone help me :
- The box is connected to the car sound system via the line in on my amp coming from the speaker out on my sound card.
- I am using a triplite inverter. Could the proximity of the inverter and its input power cord's proximity to other wires have anything to do with my problem?
I REALLY would love some help, I am going on a road trip soon and wanna have this working.
