I want to replace my speakers but this is the first time I have come across a system that uses dual voice coiled speakers all over the car. There is no wattage written on the speakers just 2x2ohm. I figure that a set of Fosgates that were 50watt 4 ohm with the adapters for the plug would work. The adapter bridges the speaker wires in parallel to the speaker. I got the fronts installed and it kept cutting out. I don't want to replace the head unit. Any suggestions?
