My Bose front door woofer finally died and I'm in the process of upgrading speakers. I have taken my door apart to remove the old speakers. I have purchased spacer rings since those 9" speakers are non-standard. I believe I have three tweeters across the dash and 2 front door woofers. My question is, if I buy a component system that has 2 woofers and 2 tweeters (and they usually come with passive crossovers), since my Bose system was already setup with woofers/tweeters, do I need to use the crossovers, or can I just plug and play?
