seal the junction with a small bit of caulk around the exterior
perimeter of the speaker.
A drill is used to slightly enlarge the mounting holes in the
speaker so that the weight mounting screws hold the speaker
tightly to the weight. In this installation [6], I milled the weight
down, leaving the original top shape on the rear. This fancy stuff
is not needed. The weight can be milled or sanded flat. Don’t
forget to mill the slot [5] or drill a couple of ¼‐inch holes. You can
see slots in the side of the weight as cast to provide room for the
truck wires in both photos 5 and 6.
Also, there is one goof in [6]. I didn’t put shrink tubing on the con-
nections to the golden white LED. I got away with it, as there is no
way that they will ever contact any metal, other than possibly the
speaker magnet housing. In that case, the speaker will short the
LED. The resistor will limit the current and the rear light won’t illu-
minate. But no damage will result. I make mistakes, too.
