Boston Acoustics RX57DIN - Manual (Page 7)

Installing Speakers in Factory Cutouts
1. Make sure the mounting surface provides a complete air seal between the front and the back of the
speaker. If the surface is uneven, or if air can leak directly from the back of the speaker to the front, seal the
air leaks with silicon sealant or weather stripping. Make sure that the sealing material does not touch any
moving part of the speaker.
2. Attach the wires to the speaker.
3. Attach the assembly to the factory cutout using four of the supplied #8 sheet metal screws or other
hardware. Tighten the screws just enough to seal the woofer against the mounting surface. Do not over-
tighten the screws.
