Decided I miss having good speakers in my hummer since having them in my truck so I'm goin to get some good component speaker for the doors. I don't see much room to put an amp in. I'm guessing passenger seat is about it. So how much room do we have under there? What amps are you guys running so I can check the specs and see what the size is to get an idea of what works. Also, has anyone installed tweeters in the back seat area? What location? Thanks

 

You have zero room under the rear seats, and only a bit under the front seats, not sure if it's enough to fit an amp in. All of my amps are mounted to the back of the rear seats.

 

Not sure what model you have but on my H3 the sub & the amp are mounted inside the rear (driver side) panel area.
