please can someone explain crossovers

[silvermilnec]

Hi all. This is my first post so be kind!!

I recently purchased a Y2000 C2 with the sound upgrade (speakers in the door)

I want to upgrade the audio system and wanted to start with the front dash speakers.

I've changed speakers before but just changed to coax type speakers never components.

I've no problem with adapting the front dash grill to fit the new 4" speaker and 1" tweeter but i've never done the crossover bit! Please could someone explain how to wire from the speakers to the crossover and then to the om amp.

Any pictures woud be great.

By the way a great site full of great advice, can't wait to do the garage door switch mod, great idea.

Cheers Chris.

get a good competition pair like MB,RF,CD then will come with a pair of 6/12 db passive crossover.

Along this line.

Us Boxster owners who put in rear speakers like to ues the 996 amp. The Boxster has a 4 channel amp and the 996 has 6. The extra 2 channels are used to power the rear speakers on a Boxster.

The 996 amp comes in 2 versions. 1 for the coupe, and 1 for the cabriolet. Either version works, but why is there 2 versions? The Boxster of course is a cabriolet. I asked one of the mechanics and he thought it had something to do with crossovers. Does this make sense?

Possibly, are all of the speakers in the same locations for both coupe and cabriolet? And are they of the same size? There could be different crossovers employed to compliment the speakers used.

Essentially a crossover is designed to pass the appropriate frequencies to the speakers that are best designed to handle them.

An example would be this; the woofer by design is large and designed to move lots of air, a tweeter is small and has a light fast reacting cone to radiate high frequencies. So sending hi frequency sound to a sub would or low bass to a tweeter would be inefectual, as each are designed to reproduce a specific range of frequencies, in fact connecting the tweeter to the "bass/low" termnal on a crossover would likely damage it.

This is just the basics, and there is a lot more to then just this...
