I got new speakers for the front and rear doors. Due to limited budget I went with Infinity 6032si in the front and 6502ix in the rear. Before I start the install I got several questions:
1. Is the Metra 72-7400 the correct speakers connector for my car? My car came with the Bose system
2. Since both speakers have tweeters do you recommend disconnecting the factory tweeters?
3. Do I need to buy speakers brackets or can I just drill new holes?
4. Can I remove the door speakers grille and use the grills that comes with the new speakers? This way I have access to change the tweeters sound level

 

1. Not sure, but if not, there's always cut/solder.
2. Yes, or disconnect the ones that are party of the infinity speakers.
3. You can modify the factory brackets, but you're better off buying some from zenclosures.com or making your own with MDF and a router.
4. You shouldn't need to be accessing the tweeters once you're installed, keep the factory grilles.

 

Thanks!!
