Mobile Forums?

Does anyone know of a forum user/group that is comparable (iow, the best) to this group for car audio?

I'll start you off in a direction, ,, those are the ones I visit regularly. I get different info from each.

I can't say that these are the best, that's a matter of opinion. You can research these and ask the same question on each and you will get even more info. research, research, research...
