cant tell a lot from those pics to be honest , one thing i can see is in pic 4, the thick blue wire in the bottom right hand corner of the pic, just under the aerial plug - thats one of the replacement speaker leads that i put in, Whicever plug they are going to should be the one that gives you sound as they bypass the amp completely and are wired direct to the speakers - this is all assuming its still all wired up the way i left it!
