What's the best way to install subs under rear seat of '08 GMC crew cab w/stock touchscreen nav. system/radio?

i got a 2008 GMC crew cab truck with the touchscreen navigation system option so an aftermarket deck is not an option. how would i wire in some subs and find good subs to fit under the rear seat that would really pound? i have the bose system option as well. thanks!!

You will need to get a line-output converter, (aka High-Low Adaptor), and all the basics for an install (amp, sub, box) This box should work for under your seat http://www.bestbuy.com/site/olspage.jsp?skuId=9026323&st=enclosure+gmc&lp=10&type=product&cp=1&id=1218009776224 and for the price you can't beat it. The box can house standard subs, but with only .8cu ft of airspace, I would recommend picking up some shallow mount speakers to use, since they will be able to operate in the smaller volume. Ex: http://www.bestbuy.com/site/olspage.jsp?skuId=8773053&st=kenwood+shallow&lp=1&type=product&cp=1&id=1204331847849 And then of course an amp. Depending on what subs you go with, I would recommend something like the Alpine MRP-M1000.
