I hate to say it, but basically everyone knows what 1 thing an audio hardware company is good for. Boss may suck in a lot of departments but they make some pretty decent amps and thats about it. stay away from tweeters unless its part of a component system, and always list things by RMS pwr..peak is so full of crap.
for subs on your truck you dont need that much power since its a smaller space (unless you have a big, extended cab sort of truck) since they'll be right behind you.
Just listen to TBspyder's reccomendation, thats really all you should be running.
