Could someone offer some advice, After installing the viper 791 on a 96 lexus es300, i decided to add a dei piezo horn, i wired them with the siren(same pos. wire, sep. ground), but the output is lower than just the viper siren only. should they be wired in series? or is that the results of adding a extra piezo? ( i searched but came up short of the correct answers)..

you have to add a relay to it, to boost the output of the siren.

You can do it with just the piezo. 85-brown siren wire(just run a wire off it) 86-ground 87-Piezo Positive, 30-12volt source. Just ground the siren ground to the chassie
