OK. So, I'd like to replace the speakers in my accord. I do not want to replace the factory head unit for many reasons, so my options are limited to working with it.

Do the stock component speakers have the crossovers "built in" to them? Or is there an external crossover somewhere like what you find when you buy a set of aftermarket component speakers? I'd like to use components but dont know how much wiring i want to do. Will the factory deck adequately power a set of, say, Infinity 6 1/2" components?

If there is a factory external crossover, great, I can just swap the old for the new and use the existing speaker wires. If not...

i may decide to go with 2ways in the door. Should I disconnect the dash tweeters to eliminate too much treble up front?

Thanks for your input.
