Hey all, I'm new to the site as I recently purchased a 2004 EX in January and I'm looking to get some aftermarket component speakers. I'm probably going to get the Alpine sps-600c, I've read good things and I don't need anything fancy. My question is whether using the crossovers will have a negative impact on sound quality because I'm pretty sure the original tweeters have their own speaker wires to the head unit. Is the head unit programmed to only send mid-range frequencies to the stock door speaker since the tweeter has it's own wire? If this is the case, the high frequencies won't be there to filter out to my new tweeters. Hopefully this makes sense and someone can clear things up. I've searched the forums and couldn't find any answers, if there is a post out there I apologize.Thanks Much.
