Frequently asked questions
Can I use it on a 24 V vehicle?
The 18S W295-R is 12 V only. Connecting 24 V will damage it and void the warranty. Message us for a 24 V model.
Is it waterproof? Can it go on a motorcycle?
The control head uses stainless buttons and we show it working in the rain on our clips. Mount the amplifier where water can't pool, such as under a seat or in a closed box. Water damage isn't covered.
Is a speaker included?
No. The kit includes the amplifier, control head, microphone, wiring, bracket and spare fuse. Our 100 W speaker pairs with it.
Is it hard to wire myself?
Just 5 colour-coded wires: red to positive, black to negative, two greens to the speaker, white is a switched output. Not sure? Send us a photo and we'll guide you wire by wire.
When will my order arrive?
We ship within 1–2 days; after that it depends on the carrier. EMS transit abroad depends on the destination and customs, and every parcel is tracked.
