Memphis audio or polk sr's. All the other stuff touts mega amperage handling but the rating system is way off. a 1,000 watt system in either of those i mentioned will blow out a 2 or 3000 watt system in any other brand. Its a little pricey but not overly. You get what you pay for. Just done look at peak watts and amps and be fooled because companies realize that people know that more power means more bass but they lie about what their handle/push. For a head unit, I would go with alpine.
