These are not 6x9 full ranges so fall into a complete different category.
These are basically a pair of small free air sub woofers. Will sit in a parcel shelf and will deliver a little more base than the normal under seat unit. Don’t confuse these with a boxed sub-woofer, they will not perform the same (and should never be used in a shelf when there is a sub in the boot).
Will give you some base without loosing room in the boot. A single 10” in a box would give you more base than these mind you.
