I am considering purchasing a set of Alpine Type-r components, but I'm trying to decide where/how to install the tweeters. I want to save the money and I also want to do it myself. I've searched and have selected a few pictures of ideas. I don't want to put them in the bottom of the door, so it's either the sail panel or high on the door near the handle. Will I need to create (how?!) a new sail piece or is the stock one deep enough? I'm really hesitant to drill into my door so I think I prefer the sail. Pointers/full DIY instruction tips would be most welcome!
