I have a 2018 Chevrolet Suburban lt with Boise system l have JL 500 and 10 inch JL sub to install,l also have a Jl 450/4,to install 450 would l need to upgrade speakers or will Boise speakers handle amp?
All jokes aside, the speakers are “made” for your factory amp and you’ll likely overpower them with the JL amp. Just get some new speakers and you’ll be happy.
