new component speakers

[fire401]

I'm new here and have found a lot af great help with problems. Thanks. But what I can't find is how to connect the upgraded speakers to new mb quarts with a crossover. do I connect tweeter and mid speaker leads together? Do I just us the mid leads and leave out the tweeter wires? Or is there a way to connect both to the crossover? Or do I have to locate the front speaker leads behind the head unit?

if you're running any quartz components you need an amp or they won't sound any better than your stock speakers
