The dash is all plastic...with the tab bent it could perhaps be touching the metal cage that the sony attaches to..but i took that out so i would suspect no....

with the tab bent it does push the sled further in the dash..and since my sled does not have a curled upper lip, perhaps it is too far in so that the contacts on the connectors were not seating as well as they should..which is supported by my prior experience of pushing in that side of the empeg in order to eliminate the whine.....

but gnomes being what they are i will keep you posted in any changes in the situation

believe me i am as tired of telling you this as you are of hearing it..but...for the benefit of some useres that may garner even the slightest bit of information out of my saga..i will be back!!!
