Hi Low Converter install

Howzit Gents

Need some advise all the way from SA. :headphone:

I am trying to install a 4 channel amp, 10" sub and a set of 5" mids.

I bought a wiring kit and an audiobank 4 channel hi low converter.

I am struggling a bit to connect the hi low converter.

The converter has 8 speaker wires, 1 x right rear + & -, 1 x right front + & - etc.

According to my knowledge the front wires are wired to the back of the head unit by way of a purple and grey wire and the rear wires with a brown and green wire. That's basically four wires. Where do I connect the remaining four speaker wires?

Thanks in advance
