Yaris Sedan Deadening and Sound system upgrade

[ezhacker1]

i did 50 ft of edead 45, that got out most rattle made the doors sound much more solid when closing. I do have rattling when sub goes but i honestly dont care as long as i cant hear it inside. The thing i do care about is the front speakers being about as loud on the outside as inside. How would i go about keeping sound inside, those foam things? If all else fails i would just put speakers in the side air vents seeing they point at me, i would get the most sound per volume setting.
