First remove the speaker back plate.  this may be easy or difficult depending on the speaker.  If its impossible, you can remove the woofer instead to get access to the inside.

Inside the speaker (usually attached to the plate) is the built-in crossover.  Remove this and note the labels on the wires: you want to identify the "+" and "-" wires for both the woofer and tweeter.  usually it is also labeled on the woofer and tweeter itself if you need to double-check.

cut the wires to the crossover and remove it.

also, check around for where you have enough room to mount your amp and crossover.  on the Peavey PR12N, the plate is big enough to fit the amp.  The Pyle PPHP121 has a really big plate, easy to work with.  On the Behringer B212XL, there is no back plate at all, so i'll glue the amp inside the box somewhere.

Another option if you have no back plate - you can route all 4 wires from the woofer and tweeter outside the speaker, and attach the amp on the outside.
