Hi there, I need some help and advice on speakers. I was gonna get some Polk MM 651 or DB 651 with your spacers but I have some questions on the rears. I have an Alpine MRP-450 and a Kenwwod KSC-SW10 but the rear stock speakers are doing anything. Not sure how the installer wired everything. Maybe you have an idea on what the installer did??

Feel free to email j.bader@hotmail.com

Thanks for your time.
