All you need is a lead to the battery to power the interanl amp, a switched +12V like from your lighter or if you want the power ant. from the head unit, a clean ground point, and to tap into your factory speakers to provide the signal. The amped Bazookas have a built in line adapter so you can run a speaker level input into them. The whole process should only take about 30-45 mins if your careful. If you haven't used or heard a Bazooka sub before be warned that while you will get bass, they are very punchy in sound, you won't get the rolling bottom end like you will with a true enclosure.....but for those in a pinch, why not go for it..
