Wondering what my options are for wiring a sub and amp to the stock head unit. AND if that can't work what the next best thing would be

I'm pretty sure you can get that to work. You would just need a converter to convert to RCA cables for the input to the amp.

so the converter will connect in the back of the head unit then ill run that to the amp

The hi/low converter taps into speaker wires and changes the signal to a usable RCA Jack. You can tap behind the radio or anywhere else. You'll also need a remote turn on for the amp or run an on/off switch so it isn't on all the time.

You need a line out converter. Do you have the infinity system?

Get a line out converter and slice it into any speaker wire. They are only about $15 or so.

Bought a Sound Ordnance powered 8" sub. Uses speaker level inputs and it fits right under passenger seat. Good addition to the stock system. I found a head unit wiring diagram in another thread and tapped into a pair of speaker wires on the back of the head unit.

Not exactly. If he does not have the infinity system, it needs to be spliced into the left and right speaker wires. And if he does have the infinity system, it needs to be spliced into the wires for the factory sub AFTER the factory amp because the amp is crossed over to not play low frequencies to the speakers in the dash and soundbar so you cannot splice into those wires. If it is spliced into the left and right BEFORE the amp, you will not be able to controll the volume of the subs (stereo can be at 0 volume and subs will be at max volume).

I'm in the process of doing this now. I'm running all new speaker wire tho so I can bypass that annoying volume decrease with top off instead of doing a jumper on the rear plug. The converter u want is called an sni

So the signal before the infinity amp is not volume controlled?
