I have a 2010 Aveo5 with the OEM radio with no cd. I can hear the vocals just fine with the OEM speakers I would just like to add more bass to it. Would a crossover work to help that? I dont want earthquake bass,just more than what is there, that is why I was thinking of the 10" woofer. I am trying to keep it simple I dont want to have to install a bunch of new things nor do I want to buy a bunch of new things.
