Matt, What is the next "step up" from the Clifs in your opinion if I can spend a little more on the front 6.5's? Also, what about a recommendation for a reasonable sub that would be adequate for me--I'm not at all looking to go bumping around my neighborhood--just round out the low end that those 6.5's can't (especially if I don't have the 6x9's to add anything). I'm curious about placement too as I have the back seats folded down frequently because of dogs so I need something as out of the way as possible but I'm a total novice and really don't even know all of my options much less what is optimal. Thanks immensely....again. PS--any particular Hifonics model? To drive those 6.5's and a moderate sub. I have a Pioneer P4600 HU right now.
