Installation and cabinet guidance

Allow for a 52 mm opening and the 57 mm frame, with about 9 mm behind the panel for the body and solder points. Seal the rim to the panel so the front-side protection is effective.

Solder to the rear points, observe polarity and keep the drive within the 1 W rating from an output stage suitable for the 8 Ω load.
