Problem with Kicker IX405D

JoergST · 31st December 2009, 04:22 PM

Hello I have a car amplifier from Kicker IX405D it is a 5 Channel amplifier.
I think somebody trays to repair ist but failed. If somebody here who has got a schematic or a circuit diagramm?
There are two IRF640 and three IRF9640. I think this is wrong, because there must be all IRF 640 or all IRF9640.
And some resistores in the power supply are burned. If you want some more detail pictures write me. I have got 20 pictures. I packed it in a rar with 16 MB.

email me.

The outputs are the correct ones. This type of class D amp almost always has more P-channel FETs than N-channel FETs.

Thank you for the diagramm. I will try to repair it.
I hope the small boards on the mainboard are not defect, because it is very difficult to get them out.
First thank you very match for your help. I contact you when I have problems to repair it. But my english is not so good to explain my problems in english

All of the boards should be repairable unless they're badly burned.

Your English is better than half of the email I receive from people who were born and reside in the US. I'm sure we can help you get it repaired. This type of class D amp is typically pretty easy to troubleshoot.
