[QUOTE="keep_hope_alive, post: 8658252, member: 576029"] It is common to see a high pass filter on stock speakers when a sub in included. rear speakers may have a different factory crossover point, each car is different. It is more common for the front speaker signal to be more reliable for full range when adding a sub. You hope the stock sub doesn't have a high pass filter on it either. The factory sub should just have a low pass filter, but given that many are free air, there may be a high pass or subsonic filter also. You can test for that in a number of ways, if you're interested and have a selection of tools for measuring voltage or a computer RTA program. [/QUOTE]
