I have a 2012 RGC-with-boom audio front speakers and amp as well as the iPod thing in the saddlebag. The front speakers are plenty loud and I find my self even lowering them occasionally (thanks to my madstad windshield) but--there's no bottom or bass to speak of. I like the way the HD lids (CVO) look. My question is, will I hear any real bass using these types of lids (I realize I will need another amp in addition to the speakers) or will I need bigger lids for bigger speakers? Also, in the end, will I be able to hear/feel bass @ 80mph on the super slab? Is it worth the expense?
