ive got a 2013 sho with the sony stereo and it just doesnt do it for me. i have zero experience with car audio so i dont know where to start. id like better sound quality and maybe a little more volume. i want to add a sub along with upgrading my speakers. what would be best to start with? or should i wait until i can do all of it at once? is it possible to run a small sub and upgraded speakers off one amp? can i do this and keep sync and the stock touchscreen working? if anyone has any recommendations for what would work well product wise and where the best place to order stuff from would be i would really appreciate it... ive found videos that answer some of my questions but help specific to this vehicle from someone who has worked with this before would be awesome. it would be cool to hear about what youve done to your vehicles too. thanks for your time....
