Newbie here but a lifelong Chebby driver. I just traded in my 2018 2500HD LTZ on a 2021 RST Rally Edition which was a big step backward as far as options go but because of some recent surgery I had I could no longer get into the 2500 comfortably and also the dealership offered me $3000 less than I paid for it 4 years ago so I couldn't say no lol. My question is my 2500 had the Bose stereo in it with all the bells and whistles and this 21 has the 8 in head unit but doesn't have the Bose speakers and it really sounds like poo. Has anyone here upgraded their speakers and added a sub to their 20 or 21 1500 and if so what speakers did you go with ?
