Stock Head Unit Sounds Great Now!! I installed in my 2019 Silverado Next Gen Crew Cab added a kicker remote bass control ( so can cut bass back when little one in back) and Kicker KS Series in both doors. Turned Bass down on Head Unit so Sub handles Bass and that doors get the Mids And Highs. Worth the Money and looks Great also Factory Looking, Shopchevyparts.com Cheapest Price.Took about 1.5 hr to install. Great instructions.
