I have an 05 F150 Lariat Supercrew.. I didn't get the factory sub because I had heard some bad things about them. I have some JL W6 10" sub's I want to put in there, but to do it I'd have to purchase a rear seat lift kit which would include taking out the back seat, adding a 1" lift bracket, and reinstalling. Not interested.. There are tons of premade boxes that fit under the rear seats. I want to get one of these, and I believe they hold 10's and another version holds 12's. I want to possibly go Boston Acoustics for the door speakers (6x8 in front and rear). Question #1: 2-way vs 3-way.. Obviously 3-way are more clear? Any reason I should avoid 2-way's? Question #2: Recommend a sub.. I know Boston Acoustics has some subs, but not sure how they sound. I need something clear, something tight, but something that hits as well. Remember I'll be downgrading from JL W6's. I have a Zapco 750 amp, but will probably sell it since its like 3 feet long and I can't really fit it anywhere.. So remember I'll need subs that will work on a 500w amp that may be 12" long that I can fit under the front seat.. Also - I'll probably stick with factory deck. 6-CD in dash, and it flows with the dash nicely. I don't want to put in aftermarket and have it look like shit with the double-din to single-din dash kit, etc. HOWEVER, I plan to purchase the Eclipse AVN-2454 HU in a few weeks, and then the whole deal will change. OK masterminds. GO! The goal of this truck's sound will be crisp, clear, tight sound. Clarity is my #1 goal.
