Installing Your Speakers From The Front Of The Bulkhead

Mark six screw holes from the largest hole pattern on the template, but do not drill yet. You may need to mark and drill a different set of holes along the same circle before finally attaching the flange.

Note: These markings are important to help keep the saw blade inside the line you have just drawn.

Drill a starter hole that is large enough for your sabre saw blade. Be sure to drill inside and close to the line you have marked.

Using the sabre saw, cut the hole for the speaker, carefully staying just inside the line. Take your time; you want a smooth edged circular hole.

CAUTION: Be sure to stay inside the line you have marked, and in particular, be sure to stay well inside the hole pattern you have marked. The marked holes, or others along the same circle, will be used to secure the speaker and must not be too close to the speaker hole. It is also important to stay inside the line because any error you make could be visible after the speaker grille is installed.

B 5	Use a half-round file or wood rasp to smooth out
	any roughness in the speaker hole you have cut.
