I think you'll be diggin' the Infiniti's, I used two of their panel units for my rears & they work great in conjunction with the RF's I used in the front.
Of course I couldn't do anything like a normal person would, so I mounted the Infinitis in small speaker boxes I had laying around & mounted them to the B pillars...poor speaker placement problem solved, & as a bonus, I didn't have to remove the rear interior panels.
And yes, my way is a bad idea if you have a back seat or are concerned with resale value.![]()
