Multi Tone Vehicle Speaker System for 12V Vehicles

Looking for an external speaker system for your vehicle? This system features seven selectable audio tones and a handheld microphone for compatible 12V vehicle installations where permitted by local regulations.

The control unit plugs into your vehicle's 12 volt battery and draws 80 watts during operation. You can select one of seven audio tones using the control switches or use the handheld microphone. The external speaker connects through your vehicle's electrical system.

It produces up to 135 decibels and includes seven selectable audio tones. The handheld microphone provides voice amplification through the external speaker where permitted by local regulations.

The amplifier tucks under your hood or behind the dashboard without using passenger space. It connects to standard 12 volt automotive batteries in sedans, trucks, and utility vehicles. The speaker housing handles rain, road spray, and dust while keeping sound output clear.

  • 135 DECIBEL OUTPUT: Produces high-volume audio output for compatible 12V vehicle installations.

  • SEVEN AUDIO TONES: Select from seven different audio tones using the control switches.

  • HANDHELD MICROPHONE: Includes a microphone for voice amplification through the external speaker where permitted by local regulations.

  • 80 WATT OPERATION: Runs on 80 watts providing consistent volume levels without excessive battery drain during prolonged use on highways or streets.

  • 12 VOLT COMPATIBILITY: Connects directly to standard 12 volt car batteries fitting most passenger vehicles without requiring electrical system modifications or rewiring.

  • COMPACT COMPONENT DESIGN: Installs in tight engine compartments or dashboard spaces preserving interior room for passengers and storage without taking up cabin space.

  • WEATHER RESISTANT HOUSING: Speaker housing handles rain, mud splatter, and dust exposure while maintaining clear audio output during storms or rough conditions.

Confirmation came through straight away, then another email when it was sent. Tracking worked and the parcel arrived when they said it would. Nice and straightforward

Benjamin Foster

Nothing missing and no surprises when I opened the parcel. What turned up matched what I’d seen on the website

Hannah Lewis

Had a look around before buying and this was a fair bit cheaper. Arrived as expected too, so happy with that.

Sophie Bennett

I emailed before ordering because I couldn’t work out which option I needed. Got a proper reply explaining the difference, rather than just a link back to the page I’d already read. Might seem a small thing but it helped me decide. Placed the order that evening and I’m happy with what arrived.

Harry Collins

My first order was only a small one a few months back. That went well, so I checked here when I needed something else. Different sort of purchase this time but everything was just as straightforward. Saved me another evening of looking around!

Daniel Thompson

Ordered Sunday evening and it was here Tuesday morning. Wasn’t expecting that, especially ordering over the weekend

Charlotte Brooks

All arrived, all good 😊

Amelia Scott

Entirely my mistake, I picked the wrong option and only noticed when the confirmation came through. Sent an email and they managed to change it before dispatch. Very relieved I didn’t have to deal with returning it afterwards!

George Wilson

Bought it in the sale. Happy with what I paid and it’s what I was after, which is the main thing.

Grace Mitchell

Hadn’t heard of Havenholt before and wasn’t sure about ordering from somewhere new. Only bought one thing to start with. There was a short wait for dispatch, but they kept me updated and everything arrived as described. Happy with the purchase and I’d be comfortable ordering again.

Emily Carter

There was a mix-up with my order so I had to get in touch. Sent a photo over and they explained what would happen next. Didn’t have to keep repeating myself to different people, which I really appreciated. All sorted now

Samuel Reed

They didn’t have the one I wanted when I went into the shop, but suggested checking online. Managed to order it on the website later that day. Would have preferred to take it home there and then, but this worked out fine.
