my nephew had a lancer with rockford fosgate navigation and traded it for evo with aftermarket navigation which didnt work very well so i swapped them now he bought an amp and sub box but no rca outs what are my options

thanks in advance

 

you can get a line converter to splice into your speaker wires and it will have rca connections on it. This is not the optimal way to do things, but it will give you the end result you need. I did this to my lancer with stock head unit in it too, not the nav. system tho. Should work the same way. I had to run my remote wire from my amp into my fuse box tho as there is not remote line on the back of the radio

 

If you do a little searching in this forum you'll see that there are lots of threads that explain exactly what you're looking for.
