All the speakers are distorting at the same time wondering if there is a factory amp that may be bad or the radio is bad............or all the speakers are blown at the same time?

make sure the speaker is not damage first...I don't think you can add an adapter to the factory radio...try finding another used amp at the salvage yard or eBay

First you need to know if you DO even have a factory preminum system.

So everything is coming on but you have no sound from anything?If that is the case you may want to check the amp fuse.The car has a factory amp i'm trying to remember i think it is in the trunk.Look in your owners manuel for the fuse box location.If the fuse is good then the factory amp may be bad.Or you may have a blown speaker that is showing a short and putting the amp into protect.If the amp and or speakers are bad i highly recommend just buying after market speakers/amp.The price for the factory equipment is very high and there labor rates even higher lol.Plus if properly installed you will noticed better sound from the after market stuff as long as you get brand name equipment.Go to a well trusted audio shop in your area they should be able to see if it is a speaker or amp problem if your fuses are all good.They should be able to test the impedance of the speakers at the amp for you and see what is going on.

everything depence of system you putting in your car if u have no amplifire you connecting the speakers to radio as they marked i you putting one in, your speakers wires goes from amplifire to speakers there is no diffrent way of connection. also the diameter of your wires have to be adekwate to power u going to have in your system for optimizing the sound quality let me know if this help ya
