Component Speakers
Aftermarket components use a much better filtering module and generally use much better materials than standard two way speakers. Most aftermarket applications don't drive the mid-bass and tweeter with separate power sources like the monsoon system. If you're using the monsoon amp, I'd say just wire up your new components the same way as the OEM speakers to take advantage of available power. If you're using an aftermarket amp, use the provided external crossover module for a better filter since you probably have more than ample power compared to the monsoon anyways.
Two way speakers use simpler, smaller crossovers that can fit on the speaker assembly itself, usually just a simple first order high pass like the monsoon uses. the crossover modules included with aftermarket component speakers are too complex to fit on the speaker assembly. Speakers generally sound better when a high pass and a low pass filter are applied, as the midbass won't try to play frequencies they fail at, etc.
With aftermarket speakers, hook the crossover's input to your woofer wires and tape off the tweeter wires - don't use them at all. Never try to reuse the stock tweeter highpass filter with aftermarket speakers.
