I purchased the Metra install kit for the xa/xb/tc. I cant figure out how you people got the kit to work without it being loose in the dash. I tried using the factory metal brackets. no good they hold the radio to high in the dash. I tried every possible solution and it just sits a bit loose in there. I cut off all the xa/xb tabs and I just dont get it. Also did anyone hook up the blue turn on lead from your radio to the factory harness? does it have any purpose if you dont have the factory subwoofer? Thanks.
