O, I saw the Kicker subs.

What If instead I wanted buy a sub with its own case and give up space in the trunk? Any recommendations? (Just considering the different options...)

I am happily learning starting those companies websites you mentioned

Also, question 2:
Given the nr of speakers & sub I have, what configuration shoudl I use?
1 amp for 5 front spealers and one amp for back speakers and sub, or anything different? What power for the amps should I look at? I am totally ignorant on this

Thank you again
