DIY Horn

[Jeepney18]

I have a DIY project that I found on YouTube where I can make a custom horn with a sound card and have up to 11 switches. One switch for each sound.

I was able to test the sound card by using the aux port and played the sounds with the Jeep speakers. The problem I'm having is with the little amp. I need to get power to it and I'm not really sure how to get it done.

Should I run a wire from the battery to the amp? What's the best way to do this? I tried to find a firewall to run the wire the other day but I'm not sure really where to go. If anyone has any pictures, that would help.

I found a place in the hood to mount the horn, so I can also run that wire to the amp if I can figure out where the firewall is. Once I get it wired up, I need to find out where to mount all the switches.

The “firewall” is the the wall between the engine and passenger compartments.

In the passenger side footwell, there is a wire loom that is already going through the firewall. Just push a coat hanger, or something similar (just make sure it isn’t sharp), through the rubber grommet and use it to pull the wire through.

In the drivers side, there is a cut out. Not sure where as I always go passenger side. You would need to find a grommet to fit that side and then feed the wire through.

I believe Quadratec, or some other off-road site, has a video of installing the Mopar Aux Switches. It shows the passenger side firewall hole.

Google "amp wiring kit" so you can see what size wire to use, and what size fuse to use. Try to use less than a foot of wire between the battery and the fuse. The fuse protects the battery from the rest of the wire if it shorts to ground. Lastly, use a good ground point close to the amp. Bare metal is a must. Good luck.

After almost 1 year, I finally got this project up and running. I still need to find a better spot for the switches but I just wanted to finally push some buttons.

If you can understand how I wired this, let me know if you see any errors or have suggestions.
I'm switching from the momentary push button switch to the momentary on-off-on switch so that I have 5 switches instead of 10.
I have a dash cam mirror going to the other 12 volt outlet adapter.

Equipment has been sitting in the garage but I finally finished this project almost one year later.
All wired up and switches are by the center console.

For the sirens and back up alarm, do they play for a set time or until you push the button again?

I totally would have made one a cow sound.

You have options. Mine are set to basic trigger. Push it once and it will play whatever you put on it.
You would probably want to use hold looping or latching trigger.
