sorry for not searching but i'm in a hurry and trying to get this done so i can go to work tomorrow. i need to know if the non-bose systems have an external amplifier. i got a metra harness and with the luck i've had all day, i want to be certain i'm putting the correct harness in. i have a regular harness that's for nissans, and a harness that has RCAs that are supposed to go from the aftermarket HU to the stock amp (assuming i have one...). which harness do i need to use? TIA

this is the RCA harness:


this is the regular harness:

 

As far as I know the non-Bose do not have an external amp. Might want to wait for a positive confirmation though.

 

Nope.

 

so do i use the regular harness???
