I may have just burnt out my vehicle's audio system, but where?

Basically, I installed an aftermarket stereo, using a Scosche Amplifier Adapter (vehicle has factory Bose speakers + amplifier). Install worked out perfectly, everything worked to a charm except for the stereo's iPod connectivity. After I found out that the car stereo was faulty (purchased it used at Amazon, hmm), I took it out to be replaced with another aftermarket stereo I had lying around the house.

This time around, in a rush, I didn't remove the negative battery terminal, thinking that short-circuiting was a myth. (Or maybe I was just being lazy)

The stereo does not turn on.

After an hour or so of trying to fix this issue, I ended up just plugging in the factory stereo with all its original connections. Low and behold, it doesn't turn on either.

I'm thinking that maybe I had accidentally shorted the system (I recall touching the yellow battery and red turn-on wires coming from the vehicle's wiring. The vehicle's interior lights kind of flickered when I did this. :o)

I checked the fuses, replaced them, and nothing seems to fix the issue.

What did I do and what should my next steps be???

Btw, I am driving a *now silent* 2004 Nissan Pathfinder SE.

With high likelyhood you blew a fuse you haven't found yet. On my 2001it's fuses 4 and 10, yours may be different. Check the FSM, it has a gooddebug procedure.

Yeah I checked fuse #4 and it was blown.
