i have a problem with my stereo in my 03 rsx-s. i bought this car from the dealership used and i was wondering if the bose stereo system sounds weak in my car. for example the sub in the trunk barely bumps and when it does my volume is max. do you guys think the previous owner changed something or is it really this quiet?

 

my sub barely bumps too if its 02 or early 03 i heard the wires in the back of the amp needed to be swapped in order to get the real bass, some people said they had a major improvement, but i swapped and i got a slight if any improvement
