Which Package Deal Car Speaker System Is Better?

It depends on your abilities. Personally, I would install it myself and save the money. You aren't going to notice the difference in speakers because all the rattling in the trunk from the 10's will drown out the clarity of the 5x7's. If it was a custom install I would say pay to get it install but back when I was 16 yrs old I was doing my own stuff. Of course 15 yrs later, I laugh at myself for having a hoopty with good speakers.
