Go aftermarket 3 way or better. I have run all kinds of speakers. Rockford Fosgate, alpine, pioneer, kicker. I find that the power series Rockford put out a lot of sound as well as competition series Kicker. I have kicker 6.5's in the doors, 5x7's in the rear, 6x9's in the hatch all Rockford amp powered and a set of Rockford 10" subs. I always use Pioneer head units as they have a ton of settings accessible from the head unit, that and it's cheap because I have a friend in car stereo who cuts me good deals. If you have the money, spend it on a quality speaker so u are not replacing them down the road. If u lived close I would set u up. I do all my own installs. Have for the last 18 years. Lol.
