So I finally did my rear speakers... went with the non-shallows hoping they'd fit. Same as the others, I had to trim away nearly all of the internal plastic grill material so the drivers wouldn't make contact with them, and I kept the black felt/fabric material which wouldn't stay in place until I lightly prayed the interior of the metal grills with black spray paint and stuck them back in place. I like the stealth look better, and they fit and sound really good. But as expected, the system still needs bottom-end fill so a powered bazooka's next on the modding agenda. After some research I'll probably go with either a 6.5" or 8". Recommendations are welcome. (BPA)
