Will this work?

Compact powered sub, also mounted under rear seat

Is there anyting about the output options on the stock head that will prevent this from working?

umm upgrade all the speakers, and yep a line out will be needed for the stock stereo, how much room is under that seat?, amp, sub, and 4 speakers ain't going to fit, sorry.
