Well just did a measurement on the black plastic piece. Looks like theres enough room to cut out a 6" hole. I measured the stock speaker at about 3" depth, which i believe is what i heard the PG RSD's are?(can anyone verify this? and is this with the grill or just the speaker itself) Anyways, im worried if it will fit with a MDF Baffle or not. Also would it make a difference if i just used a plastic baffle and some deadner around the ring?
