Do you want some bass and have virtually no space for subs?

Would the enclosure you make be able to fit under my rear strut bar? How much would you charge? Also, I would need a 1 channel amp to power this right?

I might be willing to scrap my 10" Infinity Basslink (powered sub) plans and get this if it’s the right fit/setup/cost.

Here is a pic of my trunk with the bar shown:
