Amp repair\replaceme

[altair4]

2012 Base boxster with Bose sound.  Had the passenger side drain clog, with resultant water under the passenger side seat.  Part of the collateral damage is now no sound from any source, i.e Radio, Aux, CD or Phone.  The radio works as far as I can tell.  I understand that the amp in this MY is located under the passenger seat.

When I moved the seat forward to squeegee out the water, I noticed what appeared to be a slight burn mark on the carpet near the rear right hand seat rail.

 

So, is this possibly a fuse on the stock Bose amp?  If so, what type?  I imagine I will have to pull the seat to get to it, but I also think there is an airbag cable\sensor there, so don't want to turn that idiot light on.  If I have to go the route of replacing the amp, what specs hsould I be looking for, as far as wiring, etc?

 

All advice welcome.

 

Thanks in advance!

Dealer wants $1450 to replace just the amp.   Guess I'm off to look at alternatives.
