Powering two HU

Linking the black cable to the battery should not be a bad idea (just grounding it better). Ok have you put a Fuse in from the battery to the 2nd Head unit ?
 
I'll try to connect the black cable to the negative battery tomorrow as it's a bit dark right now and I'll get back to you.
Errr.... I thought that the fuse already on the stereo was enough, need I have another fuse on the yellow cable/red cable/both cables too?
 
Well yes the fuse for the Head unit is for the head unit but the other fuse is to keep the cable so it does not fry the cable byt apart from that it might over power the head unit and fry some Circuit Boards
 
Whooppiiee!!

Cheers mate! Don't know if it was adding a fuse or grounding it to the battery but it works now. Thanks for all your help!
