looking For some expert help please!
I started to update the standard speakers no amp as standard in the car. Changed to Focals in the front doors, underseat and shelf.
So then I wanted more and went for a Vibe Powerbox 65.4 amp, with a iso T Harness. This meant I wouldn’t have to cut any wires or add any more.
when I added this the amp is only powering the rear speakers not the front.
the amp is a 4 channel one.
I am sending the amp back to vibe to test
But has anyone gone for a similar upgrade? Or had a similar issue.
mainly what else can I check?
