What are the symptoms of bad amp/subwoofer??
The sound quality is quite nice from my 2005 LS430 but not as good as the system in Acura RDX with Tech pacakge. I am wondering if the system is working properly. Since I never heard any other LS430's sound system, I have nothing to compare to. Currently there is no static noise/flutter sound from any speakers but one thing I notice is the bass seems to be weak, even at the max level. I checked the speaker behind the rear seat, it seems to be fine (no tear and the face moves up and down with the beat). I just ordered Grom unit and try to install it this weekend. Any input is appreciated.
