I recently got a pair of Alpine SPR 60 and SPR 50 speakers on Amazon. They come with tweeters attached to the speakers but I was wondering if i should get an additional 4 tweeters to put in where the four factory tweeters are located in my car, or if it would be unnecessary. I would get the Alpine SPR 10s silk dome tweeters. The 4 factory tweeters are located next to each door handle and the four speakers are in the lower corner of each door (my car is a 2002 Saturn l200). Anyone who could help me out would be awesome thanks!
