Replacing Head Unit with Tablet Wiring?

nismo-911

I already asked bigaudiofanat and im still getting mixed answers
This is what he said

"Alright, the only reason you would need a DSP, LOC, PAC, or other is if you were keeping the stock head unit and installing new amps and speakers.

You need to make sure though that your Voltage out of your headphone jack is at least 4 Volts otherwise your sound is going to be very quiet. You might need to get a Pre out voltage booster to increase the voltage to the bose amp. "

While workshop 12 is saying the PAC is needed

I guess its going to have to be trial and error
