I just bought a MBquart system which is including a pair of 6x9 DTC 169 and a pair of PSD 216 .So sould i use the precision power PCX 480 amp for that?
What is that 4x80? I am not feeling up to looking it up at the moment.. If it is less than 100 watts RMS x4 it will do fine..but you may need to turn the gains down just to make sure you don't cook your new speakers.
