You should be fine, with low frequency of subs in the 40hz range, distortion isn't heard unless your really have a crappy amp and speakers. Adjust the gain so you have max clarity with your highs and then bring in the lows to blend in. It should sound pretty sweet. Have you put the capacitors on your mid door speakers? When you do, you will get more clarity at a higher volume allowing to adjust your bass even more. Boom Boom!!
