can i use the factory speaker wires to new HU

[Grego]

Gen 4 liberty

i have a new sony headunit and i would like to use the factory speaker wires to keep everything neat

is it a case of me cutting and soldering in the new HU or is there a harness/plug to go from sony HU to factory speaker wires,

If it's a Macintosh unit, you're in for extra work.
The connection from the head unit to the amp under the seat is a differential signal, which isn't compatible with most other head units.
So, you're going to have to run extra wires to run to the speaker wires under the seat.

Thats Ok,

once i do that , Can i just unpin at the old amp connector and solder the positve and negative factory speaker wires from the 6.5" driver , will i get full frequency from the new HU , or will the trebles have been crossovered out in the door wiring ?
