This is very simple, assuming you were going to replace all 4 speakers (non component since I do NOT want to run an external amp) and power them with an aftermarket head unit.

So basically, higher efficiency speakers that fit the evo and an aftermarket head unit that has strong internal amplification with Iphone compatibility would be a huge plus too.

This keeps it cheap, light, gives thieves little incentive, and still gives me a reasonable audio oomph for day to day driving. Any help is appreciated.
