I'm new at this, so if anybody can give me a little help I would greatly appreciate it....

I'm replacing the stock speakers in my XTerra. The stock midrange and tweeter are wired separately. I can't easily tell where or how the wires are split . My new speakers (MBQuart RSC 216's) have a crossover which expects a single set of input wires with the midrange and tweeter run from there. What is the correct way to wire this? How is the signal split in a component system with no crossover?

Thanks in advance,

Bill
