OK... maybe I should have said "easier".

One of the problems replacing the front speakers and mounting flush to the underside of the dash using the original studs is getting the nut onto the stud. The opening in the dash sub-deck is very small and there is not much room for your fingers to hold and rotate the nut. I suspect it was difficult when they built them in the factory and were working on a bench (maybe this is the real reason DMC went bankrupt). This is added to the fact that it is difficult to move around and get all the necessary body parts under the dash.

As I was trying to get the original nuts back on the studs I realized I needed a longer nut. One name for a longer nut is a "standoff." So I ordered some M4 x 50mm Brass Hex Standoffs. The 50mm length extends far enough below the dash that getting them threaded on is easy.

Also, you'll likely need washers to hold the speaker. To simplify adding a washer, superglue it to the head of the standoff. Use gel superglue and avoid getting on the threads.

Here are pictures of the standoffs:

Here is what it looks like installed:

There you go. So simply you can change your speakers daily
