My buddy is putting some subs into his 06 Toyota Tacoma Quad Cab truck. He wants to hear a few other opinions from knowledgeable sources other than my own (that would be you guys) on which would be the better choice. He will be using an Mtx 3401 amplifier, the box is 2 seperate sealed chambers about .75 cu ft. It's between 2 10" mtx 4500 or the "NEW" (this years model) of the Alpine Type S's.
