Replaced stereo - Connect Factory Sub and Aux Input

[Nick-IA]

I have replaced my factory stereo and would like to know how I can hook up my factory amp/sub and the aux input. My stereo has an aux input on the back so I would like to hook it into the factory aux input connections. I have looked everywhere and cannot find the wiring diagram for the aux input or the factory sub. I thought I have read that the factory amp is 5volt and not 12. Is there an easy kit or for this or a easy diagram and parts list to make my own?

Thanks
Nick

you will need this. double check on the exact part but this is what you will need to do that.

A bit pricey... Wonder if crutchfield would throw in something like this if you buy the radio from them?

What is the black box part in addition to the wiring harness?

No can do on the factory aux part. unless ou can figure a way to hardwire it into the aftermarket radio

Crutchfield will not supply these harnesses due to the cost. the free-b's the include are the standard harness.
