So i have 4 of these in my car http://www.polkaudio.com/caraudio/products/db570/ because my parents bought them for me and got them installed for my bday present and they are running of the HU. My speaker size is 5x7/6x8 and was wondering if i should upgrade my speakers, because at high volumes, they get all distorted, or if i should just add an amp to them. Another kinda off the point question is, whats the point of component speakers if i have subs?
