A logical assumption, but not totally accurate in this case. The T-Amp is NOT designed to run off a car battery, or to be used in a car. It is designed to be powered by 12V. Tripath state 13.2V as OPERATING CONDITION
max, But 16V as absolute max. The problem is cooling.
Yes, it will run off 14V, but it is not really good for the chip as it lacks proper cooling in the Sonic amps. 14V won't kill it right away, but a number of DIYers have had chip failure at 14V. It can be done, but proper cooling needs to be implemented. The chip will work just fine at 12-13V, so why push it?
