sub to stock head untit

I have an 01 frontier and wanting to add a little bit more low-end. It has a Rockford Fosgate head unit in it just didn't know how difficult it would be to add a sub to it. Thanks

    Is it a stock head unit from Nissan that came with the truck or is it an aftermarket unit from Rockford Fosgate?

    If it's an aftermarket unit, there should be a model name/number on the faceplate somewhere. If you can get that, we can find out if you have sub outs or not. An aftermarket unit usually does so it should be straight forward.

    If it's a factory unit, that's going to be a bit more difficult and you'll need something like this:

    Or at least a sub amp that handles high level inputs. That way you can take the speaker leads from your rear speakers and connect them to the high level inputs on an amp or an add-on subwoofer crossover and then use that to send a signal to your amplifier for your sub.
