ground the case. I assume you grounded the amps and the power supply, but you also have to ground the computer case sometimes
I've just got my boatputer running. It's a Shuttle with the standard on board, n-force, sound card serving a JL e2150 connected to a 10" crossfire sub and a Rockford Fosgate 100 powering 6" RF components.
When the amps are powered up there is noticeable hum from all speakers. I can eliminate the hum by turning the levels (input sensitivity/gain) down but then there isn't as much volume as there should be. I don't need piercing volume but think there has to be something I'm missing here. The RF 100 and speakers were part of my previous, no-computer, system and I didn't have any hum then. Ideas?
Thanks for the tip. Added a ground but in my case that wasn't it. Any other ideas?Originally Posted by wizardPC
