Does your new radio have an Aux. input? If so there is no need for adaptor. Simply remove the main circuit board from the factory radio, reconnect it to factory harness, relocate and secure it in dash opening. Add an RCA plug to the left front speaker wire and plug it in to the aux. in on your new headunit.
In your case most likely the unit is working fine, it is the adaptor that you put in. Either it is bad ( not likely) or installed incorectly. It is possible and easy to choose the wrong wires to connect to. A local Car Audio shop should be able to find the problem and fix it very quickly, only a matter of minutes with a good installer, if you will leave the dash apart and accessible.
