Replacing JBL EON 518S amplifier

[g1]

Yikes. Nothing else connected to the load is grounded?

I have no earthly idea what, but I think there must be a problem. I used a similar module in an Acoustic amp and had no problems with a grounded input.

Well, my digital mixer arrives in June, so I'll see if the subwoofer is fit for purpose, and will revisit then.

Hi guys! I have the same problem downunder in Adelaide Australia. My problem was the Power Module on the JBL EON 518S blew after someone borrowed it. So I ordered in a new Power Module for $470AUD. Installed it and it went POP also. After 2 weeks of depression I still have this JBL Sub out of order and would love to get it pumping again. How did the cheap amazon retro fit workout? If its a winner I might try it myself. Otherwise there is this option from LASE https://www.ebay.com.au/itm/25629888...mis&media=COPY

I got that last module working. Used the sub once sucessfully, and it's been in a closet ever since.

I bought a LASE backplate replacement for another PA speaker (don't remember which), and found it to be well built and a good value.

Why did it pop? What makes you think another will not pop as well? If it was a defective module you received, it should be replaced under warranty. If something else caused it to blow, another module will do the same. Have you tested the raw speaker on it's own?
