Im getting 2016 F-150 and I want to put the best speakers and and have the best quality possible. 7500 is my budget(dont mind going over a couple hundred bucks). Im looking for something that can go from country music to rap music to jazz and EDM. And have it all sound good. I do like a lot of bass but not too much to were the bass takes over the treble and voice. I already have two JBL 12" Subs with an amp. One question is do I need an extra sub or two? Or should i just keep the 2 12s? I've seen door speaker with 3 or 4 small subs and I would like to do something like that just don't know where I could find that. My budget is 7k and I need help getting started and maybe you guys can give suggestions on speakers and amps for my crew cab f150. Thanks
