Installation

1.Fix the product to a solid position with two bolts with a diameter of 8 mm (see Fig. above). Be sure that the bolts are tightened securely.

2.Tighten the cable entry device, and seal the loose cables at the horn cable entry by using epoxy resin with a length of not less than 20mm. Be sure that the sealing is tight and securely.

3.Loosen the securing nuts on both sides of the support so that the orientation of speaker is adjustable. Tighten the speaker on the bolts previously mounted, adjust the orientation of speaker, and retighten the securing nuts on the support.

4.Connect the red and white audio input cables of the speaker to the audio transmission cable inside the corrosion-resistant pipe, and securely ground the inner and outer yellow-green ground wires.

5.Connect the corrosion-resistant pipes with sealing pad between joints to ensure that the pipe connection from the horn cable entry to the audio source output terminal is airtight.
