hey anyone who reads this im new to this page and forums in general... i bought a used 2007 fit sport and i have a few questions. what after market speakers can i put in my car without messing with the stereo or adding an amp, i plan to put in an aftermarket stereo eventually but everywhere iv looked the mount alone is almost $50 which leads to my next question are all mounts that expensive? i know there are adapter things you can use (i forget the name) is it better to use one of those and leave in the stock stereo.. also can i replace all 4 door speakers without adding an amp or can it only be two?
