Stock Speaker Size H2
 

Just figured this might help someone at some point.

Front A pillar tweeter is 1" with 2" depth
Front door is 6.5" with 3" depth
Rear door is 6.5" with 3" depth
Rear pillar is 4" with 3.5" depth
Sub is 8" with 6" depth. Not sure where the sub is if there is one in there but this is what I found online.

This is what Ive been looking for but Im trying to find these specs for a 2005 H2 SUT...any ideas?

I thought the sub was a 6". And that's what the guy at the shop told me as well. I know it is under the center console but I have not dug into it to see for myself. I just added one kicker 12" and it filled out the bottom end perfectly.
