I recently installed a new set of v-max components into my truck. I'm powering them off a profile amp at about 60-80w per (estimate). So far they sound great, but they really have no low end to them at all. They dont seem to capable of getting around 120-200hz at all. i don't expect to have subwoofer like bass, i just expect to have some. Right not its up to my sub to cover a pretty broad range to get the right sound. I've been thinking the problem might be the stock crossovers cutting them off, but i wouldn't think the manufacturer would do that. I have checked all my head unit and amp settings to make sure nothing else is limiting them. Any ideas?
