Tubes only go boom when the tire slips off the rim or sustains a sudden large cut. The twing noise you heard was probably the tire lifting off the rim. There is probably a gaping hole in the tube near a sidewall. So somehow either the tires were mounted without the bead being totally seated on the rim, or there is a mismatch between the rim and the tire bead. When you mount a tire, pump it to ~30 lb first and inspect the bead all around on both sides. If an area is higher than the rest, deflate, reset the bead, and inflate again. If an area is low, deflate and try again. Liquid soap can be used in that area to help the bead rise. Only inflate to full pressure when the bead in set evenly all around. If you always do this and the tires still blow, check with your LBS or the rim manufacture for possible tire incompatibility. Checking the inside of the rim is good advice, but usually rim problems cause a hissing noise as the tube leaks, not a boom.
