What are the size of the front door speakers? For a 09 tsx tech package.

And how many watts should I replace the factory speakers with?

The front door speakers ar 6.5 inch. you'll need aftermarket speaker adapters for the new speakers. You can order them in from a specialty stereo shop or buy them on Ebay (much cheaper) I think I paid about $10. The stock amplifier doesn't put out much power so if you aren't upgrading the amp then 25-40 watts RMS. Just go with low RMS and it should be fine
