Hi I cannot find any answers for my question so here goes.
The PO fitted a new HU using an iso harness. I am in the process of fitting an under seat speaker board but im wondering how do I wire up the speakers, do i pull the existing wire from the boot or do I need to install new wiring?
If so where do I connect the wiring to? Do i solder into the iso harness or do they simply plug into the back of the HU
