Just purchased a super low mileage (16,000) 2016 Cadenza. Love it so far. Traded in my 2011 Optima which was a great car too. I've searched all over and can not find the specs for the factory Amp (Infinity system). I know it is a 12 channel amplifier but does anyone here know the wattage per channel? I've seen anywhere from 550 to 1000 total, called JBL, Kia, as well as my local dealership and no one was able to help.
