iam running a galaxy dx 95 t in my mobile i ma sure the alternator is 120 amp nowi havent grounded the radio in the manual its states radio needs to be grounded there is a red lamp on the radio just below signal metre this should light if radio is grounded what i want to know is will the radio unperform if not grounded it seems to be working fine so far should i run the black wire from the power lead to the chassis of the car or just run straight to the battery and run a separate earth as i have looked on the back of the galaxy there arent many places to run a separate earth lead from any galaxy users out there who run a dx 95 t mobile i would apreciatte any comments i am also using a wilson 1000 mag mount as an antenna thanks
