I'm looking to redo the speakers in my truck. I've already dumped some money into subs, now its time i actually got around to the speakers. I have about 150 a set to spend, and i want to get the best i can get. price is less important than quality. The doors are 6 3/4, which is a bit of a hassle, and the dash are 4x6. Ive thought about converting the dash to 6.5's if its worth it. I was thinking about Alpine R's or Infinity Kappa's, but i really don't know what the good quality brands are in speakers. Any pointers are greatly appreciated. I mostly need to learn what the good brands are in speakers. Ive searched a bunch but it hasn't been very helpful.
