Lexus amplifier replacement

Hi all, I need some advice regarding a replacement of my amplifier for my 2007 RX350. We bought the car recently and there’s no sound at all coming from the speakers - so I’m assuming we need to replace the amp. When I look for a replacement is it simply the model number 86100-48080 I need to look for? Or do the other serial numbers matter? This one on eBay for example EBay link has the same model number but different FLPG codes.

Really appreciate the help

Many thanks

The amp in my rx350 that needs replacing

 

That's the correct part number. There was also 86100-0E030 which came in North American produced models it's the same amp.

 

Thanks for that. In my car the OEM amplifier is 86100-48080. I can't seem to find a reasonably priced replacement. Could I replace it with a 86100-0E030 amplifier?

Thanks

 

86100-0E030 supersedes 86100-48080 which means both amps are functionally the same.
