Installation and cabinet guidance
Compare the 142 × 90 mm cut-out, mounting slots and available depth with the dimension drawing; nominal 4 × 6 inch size alone does not establish fit.
Use 4.8 × 0.8 mm positive and 2.8 × 0.8 mm negative connectors with a suitable 4 Ω amplifier.
Seal the frame to the mounting panel and keep the cone clear of the trim. Matching grilles are separate accessories.
