With a Bose system you will have to rewire the entire car. Bose speakers run on 1.5 ohms and the headunit simply cant support that. In addition to the HU, you will need to replace all the speakers with standard 4 ohm speakers. If its your first time doing this, budget for about 2-4 hours of time. You will need plenty of speaker wire. If you havent done this before, now is not the best time to learn. Take it somewhere and have it done, BBY will charge you 4 custom labors at 16.99 per custom and 2 rolls of speaker wire. You will also lose the warranty on your entire factory audio system if you do this yourself, dont know if that matters to you.
