You need to:

1. add a ground symbol;
2. add an input voltage source configured as an AC Source;
3. add volprobes (voltage probes) on each of the twitter and woofer outputs;
4. set up an AC sweep simulation.

For information about this and much more, please see:

If you make your project public then I can help you create a working simulation schematic.

Thank you! I'd just try but it just throw me and error :(

Thank you for your help!!

This is the error that I get:

Either add a 1G resistor from the junction of C3 and C4 to ground to provide the necessary DC path to ground from this node or replace C3 and C4 with a single capacitor of 1.65uF because 2 caps in series have a total value of C1*C2/(C1+C2).

You may like to remove the connectors because they have no model that would have any meaning in this simulation.
