why go a bigger amp. The tweeters I ordered are 50watt, 94dB

This is not a hi-fi sound system for deer. I don't want to entertain them, just want to scare the daylights outta them.
can get some 24w stereo (2x12wBTL amp chip TDA1518BQ fairly cheap ($1 but sale ends 5/1/10)
SALE! TDA1518BQ 2x12Watt Stereo Power Amplifier-The Electronic Goldmine
or go with a bigger amp
TDA8560Q 40Watt/2 Ohm Stereo Amplifier IC (Phillips)-The Electronic Goldmine
but at $2.49 I don't think so.
Plan is for vehicle use, an amplifier with two speakers, each speaker driven with 12w.
One amp has random input frequiencies of 2 - 8 khz
second amp input has random frequencies of 15-20khz.(might go higher as the tweeter is rated for up to 27khz)
all frequencies selected using a RAND NUM GEN code in a PIC.
One must realize deer can hear up to 1 mile away with directional hearing ability.
for home garden use, a battery powered unit with only one small speaker, no amp.
I need to see if the pic code will generate the 15-20khz.
a way to turn on the vehicle unit at 15-20mph.Thinking a ping pong ball in a tube w/ photo transistor circuitry.
I have 3 of each piezo tweeters ordered last night.
