Installation and cabinet guidance

Allow for a 21 mm opening and the 23 mm basket, with about 5 mm behind the panel for the body and solder points. Support the basket evenly; bonding to the panel may be needed for the front-side sealing.

Solder to the rear points with a fine iron and observe polarity. Use an output stage suitable for the 8 Ω load and keep the drive within the 0.3 W rating.
