The kicker solobaric L series are not for
infinite baffle mounting,only sealed or vented.

They have to be in an enclosure.

I know you are going to say that the trunk
is an enclosure but it is to large in volume and
you will blow the subs if you mount them that
way.
The 8" and 10" need less than 1 qubic foot ot
airspace thus the enclosure can be kept small.
