using an LM386 amp connected as a 200db gain how much wattage (speaker is 8 ohm or the transducer is as well).
output is a 5v 18f1320 PIC
presently using a .2 watt speaker but set up with 20db gain
plan is to power the LM386 either with 5v or 12v (going to be used on an automobile.)
If I can locate a higher wattage speaker that is under 1 1/2 dia or a transducer.
never used a transducer before so not real sure of usage.
needs to be water proof
pui audio is sending some samples but still would like to know the calcs behind db gain vers wattage etc.
