Hi again
When I put the orginal speaker in the CN5 (speaker output on the RX18), the sound is finde... So I guess it has to be the amp that´s blown

I don´t think the RX18got hot before theamp broke, the setup was working perfectly - I´ll try with the new amp , and I´ll give you guys an update.
Hope the ampdoesn't pull to much power out of the RX18, it´s not worth a new RX18 every week
Thanks for thehelp guys
