Built right into the speaker. Its the winding of wire and the capaciator on the bottom.

IIRC, they are the copper coils that wrap around the magnet on the mid-bass.

You can get some parts from radioshack and build a cheap passive crossover. I cant remember what they are but Ican look when I get my car back.

I've never seen the bottom of one.
Easy upgrade.

Thanks.
