Stock/OEM Amplifiers In 6.5 Gen Maxima'z..?
 

I recently purchased a 4 channel amplifier.. Someone told me that 6.5 Gen maxima'z may have a stock/oem amplifier and if so it needs to be removed before installing my new 4 channel? Has any one come across this situation? If so, where can I find the stock/oem amp and how to remove it..?
