I have an 06 Magnum and I installed an aftermarket radio with harness and once I was done turned on the car and the radio gets no power whatsoever. Did a little research to see if I may have an amp I don't know about and found out that if I did it would be under the steering column. Is there anyway to bypass or get the harness I need?

 

I don't have a factory amp....
