Do Kick panels give better SQ than using your door?

no one mentioned if an under seat powered sub would help. I saw one Kicker made and Alpine and JLA have some nice passive, ported ones, but the latter i doubt would fit under my seat. i'm sure the Kicker would though.
Could also be my memphis speakers, they were only like $99 some 2 years ago. and that was at an audio shop, so i'm sure they were far cheaper even online....i should get some decent components.

i may even consider putting my Maxxbass processor back in if i had to, maybe there's something more i could do about the noise it puts out.

which line of memphis are they the sr, pr, msync, or mcc google for them real quick
