I have a 2007 Mercury Milan with the 6 speaker set up. I am replacing the four door speakers with some Alpine SPS-57C2 2-way 5X7's. I planned on keeping the stock tweeters in. The box the speakers came in said: This product contains a high performance tweeter. If there is a tweeter already installed in your car, then you must disconnect its terminals. If you leave the original tweeter connected and connect this product in parallel, then a fault may develop in this product, so you are strongly recommended not to do so. I just need some expert advice on this. Do you really think it will mess anything up? Thank you.
