I feel the low end lacking. Also I notice certain songs, I do not hear certain low notes that I hear in my friends car.
I want to do a sub upgrade first. I don't have a budget but cheaper the better. I don't need the super high end stuff or anything, I just want good quality components and good quality sound. I get about half off all Alpine car audio equipment, so factor that in for cost.
How should I go about dealing with the OEM amp digital input and 150w sub outputs?
