Alpine CDA-7893 Car Stereo Like New Sub Setting Hits Hard

Alpine CDA-7893 Car Stereo Like New Sub Setting Hits Hard Tons of options and settings Too much too list I Love sound quality Unfortunately it's way too much work to wire in my Lincoln Towncar from rear factory Amp to in dash and having to pull passenger air bag out of dash but I almost went ahead and did it cause many newer decks/ head units don't sound this good My friend had one of these in mid 2000's in his Acura legend and you could hear him blocks away I finally discovered his cheap subs were hitting so hard simply cause he had this same alpine in his Legend I became fond of Aplibe and Kenwood after that
