I only have about 20 min driving since the change but so far so good. I have a 4 hour drive on Friday to really test it.did the -3 bass setting work for you?
So far so good with the revised audio settings! But yes I am planning on JBL combo with new front components (not sure which components though) and dynamat treatment to front doors and likely removing rear seat and doing the back wall tooglad to hear. Just get that JBL dsp amp combo and those stock speakers will sing!!
