Hi,Does anyonehave changed door speaker wires ?
I am thinking to install New door sub and Amps.
I need tomake cable route from back to door Sub.
My concern is how i can pass through the cable from body(Kick panel area)to door inside.
They might have Plastic tubes ??
I want tokeep stock 6 speakerwiresremain but Does this tube still haveenogh room for 2 more cable?
Any idea would be really great ,Thanks
