Goldwood GM-600PB 1" Horn 1-3/8"-18 TPI
What size cut out is required for this horn? It only gives outside dimension.
The cutout for this horn is 10-1/2"W x 3"H.

Can I use the GM-600PB for the GT-400CD and GM-500CD and wire them in parallel, driving them with an automotive 50 watt amp per side?
Yes, although you will want to have a high pass filter on the GM-500 and a resistor on the piezo for protection. I would recommend a 5kHz high pass for the driver and 20 watt, 20 ohm resistor for the piezo.
