hu ground?

I just got a new hu and the ground needs to be made right behind stereo without connecting to another wire. I have a 98 integra... where's the best spot to ground the wire?

You should have a thick ground belt back there somewhere. Some radios allow you to screw that belt directly to the HU while others have the ground off the port. If so, get a small wire extension, put one end in your harness in the proger place and wrap the other end around the ground belt. Make sure to use electric tape around the connection and your set.
