Can anyone help me please I blew the osf speaker decided to replace the front and rear speakers removed the offending speaker until new ones came ( nsr stopped working at this point) I've now replaced all 4 fronts work great but neither of the rear ones now work . The stereo is an aftermarket one the balance and fader are both in the central positions any ideas please

if you fade the headunit to the rear do they work?

 

Have you checked to make sure they are still connected?

 

Is the iso block in the headunit correctly and not having a loose connection?

Fully faded to the rear and they don't work I'm sure they are connected and the ISO seems fine I'm going to have another mess on the morning with it
