I have two mini speakers rated for 8 ohms each.  If I wire them in parallel, would that double the sound volume? Or at 16 ohms total, would that reduce the sound output by 50%?  The sound effect I want to install in a trackside accessory is a 12v  DIESEL HORN circuit.

Comments welcome.

The amp in the diesel sound board is the determining factor.  Can it drive a 4 ohm load ?  It will let you know in just a few seconds.  Try it with one 8 ohm speaker first.  Or, what did the board originally come in? Find out what speaker it used. Going up in load resistance will cause no harm however going down can.          j
