You may not have they proper size wire to the amplifier. Most amps now recommend 4 ga. Also make sure your wiring to the speakers are at the proper Ohm load.
Missmatched impedence, ie you are running your amp which is 4ohm load to a sub which is 2ohm load, insufficient grounding could be the cause, blown transistor within the amp possibly.
it is not a short.the knob goes to a variable resistor that has a graphite track and a wiper arm inside it.there are two kinds ,sealed and open.the open have a small hole at the back and you can spray contact cleaner in the hole and it will fix it.
if it is a sealed type,you have to spray in at the circuit board where the pins go in. not the solder side of the pc board, but the component side.
there is a slot on the bottom where the pins come out.
if contact cleaner does not do it,there is probably a crack in the track,and you need to replace the potentiometer.if it says 10k it is 10000 ohms.if it says 100k it is 100000 ohms. if you take it all apart,an electronics shop will solder in a new "pot" for you for a reasonable amount
Unfortunately, no one knows or is telling. Companies rarely state power in RMS because Peak Power is a much more impressive. 1000 watt amp, 200 watts RMS x 2 channels at 8 ohms. Look for a sticker on the unit.

The radio code is a security feature that's meant to deter theft, and it's unique to each vehicle. If you've lost your code, you'll need to contact a Nissan dealership or service center and provide proof of ownership. They should be able to help you retrieve the code. Please do not attempt to use codes from the internet as incorrect attempts may lock your radio.
The wiring is bad on the plugs and shorting out, or whatever is on the end of the cable has an issue. Also look along the cable for rodent, cat, dog chewing.
Questions like this need 'make model (what is is) of every item involved. On a vehicle 'year make model' as well.
The bad ground causes the amplifier to go into the protect mode. So, make sure to check the grounding wire and overall connection to figure it out and set back the amplifier to its normal mode.

There are a few solid state fuses inside but if the speaker wires were shorted then it required an authorised Pioneer service centre to repair the damaged amplifiers section.
