can i just switch out factory speakers? or need amp? - 8th ...

pretty new to car audio, was going to put new speakers in where the factory ones are, but i wasnt sure if you had do amp them or can i simply replace. ... If your looking to do that in the future then do it all at once the right way. No need to take your car apart twice. I like alpine and pioneer navi/gps headunits. What kind of head unit do you have? Stock? junbug30s is online now ...
