I doubt it, since you haven't given us any clue as to what the damage is, what your test setup is or how/what you are testing.
Welcome to ETO!

I hooked it up with two 15watts drivers, both 4ohms, nd a power supply of 16.8 volts

You did provide a link to the "board" (Chinese or American?) and did not say what problem you have.
The Texas Instruments datasheet for the TPA3110D2 says that when 4 ohm speakers are used with a supply that is higher than 12V then an additional heatsink is needed. Your 16.8V supply and without a heatsink probably fried the IC.
