Wow, talk about a long thread from many experienced people who have done some amazing things to upgrade their stock systems. I appreciate everyone's input I have been reading over the last 68 pages. All that said, there is a lot of info and acronyms mentioned in these posts that I am not sure I follow. Firstly, I would never considered myself an audiophile, but I do like a nice sound when listening to my mostly country, but sometimes R&B/Hip hop music. Secondly, I am leasing my truck, so I want everything I do to be inexpensive but quality and completely reversible for when or if I return my truck. I was sold on the Infinity Reference series, 3032cfx in the dash and 9632ix in all four doors. Problem is they are all out of stock at Crutchfield, due to the pandemic I assume, and this leaves me in a conundrum. So my questions, does ANC affect the quality of a Bluetooth conversation or just keep the cab quieter for the MDS? And what and where is the LOC everyone is talking about. Due to it being a lease, I probably won't add a sub. Just want better sound from dash and door speakers. BTW, for your reference, I am rocking that amazing base 6 speaker system. Affordable/inexpensive speaker suggestions are appreciated as well.
