Id run a single ten in there ..like a dayton HO, and grab a couple amps from Jim/Mylows10, that will be excellent, and save some space while not giving up some power..Id recommend the Ab 26801 on sub duty while looking at the 150.4 AB mini Hybrid on a 3 stage up front,one good AGM under the hood, and the BIG 3,and a decent HU, and she will slamm as well as be quite effecient.That truck should have a stock 140 amp alt..Neighbor has both amps and a single Orileys Super Start Extreme AGM, and Big 3,in an xcab with a Single AudioTechnix 12 in 1.4@35 htz ported enclosure under the back seat(switches to 2-xfl 10s from time to time,an Infinity 6.5 90 rms mid,and CDT DRT-25 set of tweets,and a set of Infinity 4x6 in rears with a bass cap and she does nicely at all times.I say Dayton HO 10 do to SQ, and they take a limited space of 1.0 sealed to sound fantastic/especially on that 26801.d,and the space behind the seat or in center behind console should fit perfect.CDT 3 way up front will sound excellent in that truck..6.5 and 3/4 tweets should fit in stock locations easily and do one cut out for a clean finish for the 3-4"mid.Be an awesome setup in that truck..or even a two way..Just my 2 cents..
