Question

which one would be more louder? with a 1000.1 amp ? the boston or the 2 kicker l5s

and which one would sound better too..

Answer 1

No question the two kicker l5's. I always recommend kicker when it comes to subwoofers. Go with the kickers they will sound better and last forever.

Answer 2

what ever on has the higher sensitivity.over 90 is good

Answer 3

Question is what is more important?  Louder or sounding better?

Louder, 2 x L5's.  Sound better, SPG555.  The SPG555's are made for a more sophisticated car audio audience that believes in the importance of sound clarity.  Do not kid yourself, that is one sweet sub.
