Just got a ATOTO A6 double din head unit and I went to install it, realised I forgot to get an adapter for the plugs but then as soon as I took the not working stock radio I found all the wires cut. Should I try figuring out how to just connect the new double din radios wires to the cut wires or should I go to an audio shop and get them to figure out how to install it for me?
Or should I just try getting the factory radios plug wired back up.

Since the connector has been cut off, you could just wire directly to the new radio harness.
Here are pics and info that will help you. Not that bad of a job.
