i don't have any big updates as of yet, since i have only changed out the head unit since installing the raammat. when the rest of the system is finished in the coming months, i'll be documenting and reporting.

i will say that while the raammat certainly helped isolate road noise, i'm afraid i will be replacing the dual glasspack mufflers installed by the previous owner. just too much noise at cruising speed. when the exhaust work is done, i think the audio environment will be excellent, though i don't have a baseline to compare it to with this vehicle.
