id get a Alpine 7995, hell yeah. 300 bucks off ebay or some yahoo store i saw someone post a link to. If ud like to spend like 50 bucks more u can get the 9815 which is basically one of the best HU's. So many features u dont even need actually. Id go with the 7995
If im not mistaken the 7995 doesnt have an internal amplifier so youd have to buy a component amp to go with it. I think crutchfield has a sale on them right now for $300 and they are an authorized dealer of alpine so the warranty isnt void like it would be if you bought it from some store on ebay. If you had it installed by a local authorized alpine dealer i think you get a 3 year warranty. But i could be wrong. I normally wouldnt buy from crutchfield cuz they rip you the hell off but if you cant get it cheaper anywhere else then crutchfield is the way to go.
