This is great info. Thanks! You Canadians are alright.
I feel like the dash needs to be dialed down a touch anyway. The Alpine 3.5" sound overwhelming above about 26 on the volume...to me anyway. The low end in this set up is so poor that the highs just take over. A small dB drop up front might be just right to find some balance. Feels like tin in my ears as it is right now when it's way up.
