hello, my cuz just got this amp, autotek sx777. 6 ch at 75w@4 ohms. + 1 mono ch 250w @4 ohms. he wants to use this in his tahoe, now, he want to use the 1 mono channel for his center channel speaker, is this possible? will he receive the right frequency with a good component set/crossover im just worried hey may pop his tweeter, should i tell him to buy a small amp for his center channel, and leave the mono channel alone? thanks
