I have a 16 Silverado work truck and mine has the two in the dash door speakers and rear speakers I’m waiting to do the bullet midrange 6x9s on my doors and go with some 4x6 speakers or bullet tweeters as well for rear but I’m kind of second guess from what I’ve read about those rear speakers not getting much output anyway . And for bass I’ve got my eyes on 2 10 inch powered underseat subs . That way I have no space lost in the back . Let me know what you guys think
