So I'm kind of getting tired of the crappy speakers in my Elise. I have the Blaupunkt speakers and stereo. If I leave the stock stereo and just change out the speakers, will this make a difference. I don't want a loud bumping stereo but I just want a nice clean sound without the crackling when I turn the sound up. So my next question is, is this something I can DIY or should I take it into the dealer and have them do it? And what would be a good speaker to upgrade to? Any thoughts would be greatly appreciated.
