I need some help with installing better rear speakers. I like to install it in the original speaker location and it's counterpart on the right side. It's easy on the left side where I have room and the original speaker's mounting panel. The problem is on the right side where I don't have a mounting panel and some hoses appears to be in the way. If any of you all out there have installed speakers in that location, please let me know what size speakers you installed with some mounting instructions. Thanks
