if you using the hertz crossover, just solder your input wire to the speaker wire from amp. then the rest can use the crossover supplied wire.

if you are running active, then all wire direct to the speaker terminal but for tweeter the connector is too small to accept 16awg, so cut the oem wire as short as possible like say 4 cm, then solder your 16awg with it.

I dun think you can hear a difference with the 16awg direct to terminal / go thru the ori smaller wire at such short distance. This method have lower chance to break the ori tweeter terminal. you wont want the less flexible 16awg to break the copper lead from voice coil to the terminal if you accidentally snap the terminal out.
