Sorry about the Late response.
These do very nice and will fill that 4Runner cabin very well.Do throw the subs in a Prefabbed enclosure man. Get a decent ported and tuned enclosure done. You can even get a Glue and DIY Enclosure from GP Audio.d get tuned to a min of 30htz for these and up to 36. I have a 4.0@32htz and slot ported same side as subs.
