Echo HB Install questions ***Please help me

[INkonspyk]

I have got a 2004 Echo Hatchbar 2 dr model. I need to know a couple of things

+ how much space am I working with in the trunk to do a multi subwoofer install?

+ Is there any way to but speakers in the back seat area of the car? (currently there are factory speakers in the dash and the doors)

+what size are the factory speakers? <so I can replace them with higher end ones

You can do over 10+ subs if you are creative

I'd just run dual 12's in a sealed enclosure. Ditch the rear speakers all together, and use the money you were planning on using for those, put it towards components for the froint, and a decent amp.
