Just remember it's all based around non-standard 2 Ohm speakers and the head units have to be put into Bose mode (lowered output to drive Bose Amp correctly) and your about covered!

If you  want to improve the system in any way you will have to loose the whole setup: Speakers, Amp, Headunit, Bose Loom. You will also need to loop the speaker connections back at the kick panel connector (assuming you already have Bose equipment).
