David's Car Stereo. It's a local place here and they're an authorized Alpine dealer so I figured they'd know to run the 10 gauge. As far as the amp, it sounds fine now so I don't think I'm gonna bother getting it bypassed. Also, there is a feature on the 9835 where if you're using an external amp you can turn the internal one off and when I tried that there was no sound. Maybe that means they bypassed the factory amp?

Also, any suggestions on getting rid of the static sound? Or does anyone know what I'm talking about?

Edit: The static hum or whatever you want to call it seems to be coming from the right tweeter. It wasn't there before I got the new HU installed so I'm guessing it has something to do with the wiring they did while installing it. What can I do?
