thanks for looking into this case allready. Though I dont understand where you are ghetting the 3 Ohn from. As far as I always learned, when you put two resistants parallel, you have to devide the amount, and double the wattages.
So when a speaker would be 300 watt on 8 ohm, put a second speaker parallel, you would get 600 Watt on 4 Ohm.
The XLS 602D should do the job on this I was thinking.
Today I have serviced the first amp, and I found out something strange. When I installed the replacement amp last night, I saw a red led burning inside of the amp. This new amp is working fine, but it has not been crowded yet in the bar dancing so I have to wait till saterday night to find out if the replacement really worked out and nothing wnet wrong.
Back to the story, when I was doing dust cleaning insite of the first amp, I found out, there was no led at all on the print..
So now I am wondering if there has been a modification during the past couple of months...
Serial # of the first amp (with no led inside ) is : 8500034324
Serial # of the second amp ( with a red led inside ) : 8500052137.
Looking forward for your answer...
