hi.

i wonder if anyone has made some speaker upgrade in their car?

i have a vibe pnp kitt installed with a match 8upw amp.
i had the basic system as oem.

i wonder if i need to upgrade the under seat subwoofer housing to the harman kardons?? they look bigger!

how have you guys done with the dampening?
