Hey guys. Just bought my N3 and was wondering if any of you had some pointers on installation. I notice now that when i first start it up, if i leave the cars audio loud when i shut it off, the car while start quite and gradually get back to where i left off at. I also notice the faster I'm going the louder it gets. Is there a specific way to wire the N3 to my audi harness? Any tips would be appreciated. Thanks
