2005 dodge magnum rt won't start

Hi, i have a 2005 dodge magnum and it was working fine. My radio screen was lighting up but no sound was coming out so he was trying to get sound. He connect some wires behind radio and cut some and was trying to re run it and now my car won't start. The dash light up and the battery click sound happens but it won't start. We even tried jumping car but it won't start. We let it sit and still nothing. Is their anything we should do? Please help.

Connected some wires and cut some wires? That sounds ominous... Just because the wires are located behind the radio, doesn't mean they have anything to do with the radio. The wiring in a lot of cars in the last decade or so has become complex and sometimes a bit messy (Chrysler wiring can be very messy). You've got a situation that a Chrysler/Dodge specialist really should look at. I can only begin to speculate what could be wrong, it could be something cheap and easy like a relay or solenoid, or it could be a wicked pain in the ass electrical issue.

Put the wires back where they were.
