hi,

i'm in san francisco, california and i should recieve my unit in the mail today or tomorrow. i am going to have a professional install it, because i don't know enough about electronics to know which wire does what. It seems from what I have read that the empeg install is a little more complex than a regular unit, something about a "grounding wire." So i am wondering what i should tell the installer so he gets it right?

thanks much!

joe
