Jumping in to add some comment.....
Would suggest to wait for a while and change HU & Speaker together and work to getting something that compliment your budget (save up more). Change together maybe can save some installation cost and get better compatibility.
Currently if ichy hand/butt can do sound-deaden for the car as insulate external noise will enhance current stock system slightly and as first step before jumping into next step. Also help on ride NVH levels.
