has anybody tried to change out the front & rear speakers with cdt audio cl69 or m6's ? i want more bass from the doors, but dont want to add more power. i figure a larger 6.5" midbass/subwoofer for the rear door, & any 6x9 would fit in the front, but dont know of any that would be comparible to cdt audio. the rear looks to shallow to do much. i have the factory rockfords in the doors right now that came out of a crew cab. they have impressive bass for what they are, but i'm looking for more. dont want anything that isn't a component type woofer.
