I've got a 2011 Silverado with Bose and saw on the schematics that there are low level audio signals going from stock HU to amp.Can I just tap those and attach RCA's? I mean,does anybody know if those signals are full range and suitable for an aftermarket amp?

It is full range. Probably not enough level to drive an aftermarket amplifier.

Play a test tone somehow, set meter to ac volts. Turn radio up as loud as you feel comfortable with and read the voltage. If you anything over 1/2 a volt you should be ok. Are you just adding a sub amp?

Thanks for the reply,yes I am just adding a sub amp.The reason I asked was because I did a 2011 Terrain and the stock low levels were putting out 6.6v AC.It was showing that on both my DMM and O-scope so it was accurate.I just wasn't sure with the Bose setups as I'm only familiar with the older GM Pioneer setups.
