Well I go my amp and sub transferred to my new Frontier yesterday. My Silverado Z71 had 2--12" subs in a box along the back wall with the stock Bose system and a 600wat jbl amp. My frontier has a high end Kicker 10" sub in a box under my rear passenger side seat. The 600 watt amp is under the front passenger and I also have the stock Rockford Fosgate system. The frontier has way more thump with just one sub than my Silverado did with 2 bigger subs. Of course the cab of the Frontier is much smaller.
