Hi. I have an alarm and it is currently connected to the speaker that came with it. My problem is the sound is too soft. Can I instead connect the output wire the the + side of the car horn? Would there be any problem? Do I need to connect a fuse in series with the outout wire? Thanks.

Kinda need to know what year, make and model of the car along with the model # of the alarm. If the alarm has a low current horn output, you need nothing. Just plug the wire from the alarm to the car wire. If not, you can use a relay to convert the siren's + output to a -output.

my car is a celica 1989 ST manual and I just installed the car alarm myself. The wire that comes out from the alarm is color brown to be connected to the Siren (O/P +1A). Thanks.

Does the alarm have a horn wire? If not, can you program the siren wire to be constant or pulsed? You may not want a 35 second straight horn going off. You can always buy a different siren.

The alarm box has the model : OP168-6-C ... It's a generic car alarm that I bought from eBay. Thanks.
