Nav Rear

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.

And then of course an amp. Depending on what subs you go with, I would recommend something like the Alpine MRP-M1000.
