I don't blame you for getting the rear speakers so your wife can hear, or hear better. I am not exactly a fan of how those look, but that's just my personal preference. I did rear speakers and spent about 1k doing so (HD saddle bag lids, speakers, etc). My wife is only slightly happier. I can't hear them at all in any way shape or form whatsoever. It seems as though they were louder at first and possibly are not as loud as they used to be??? I don't know. The dealer that installed it said all was well. I will be getting an amp at some point. I have to research that. I'll likely get HD so there is no problems with the speakers or radio, even though aftermarket may be louder. I don't need an amp for me because I hear the front speakers just fine, but my wife still can't hear well at I-road speed. You will likely be buying an amp too.
