Installation and cabinet guidance

Allow for a 20 mm opening and support the metal basket evenly; bonding the speaker to the panel may be needed to achieve 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 1 W rating.
