Hello Everybody! I'm looking to replace my crappy 6.5" Performance Teknique speakers from the doors (Previous owner installed those) but I don't have an idea which ones will make it better.

I don't have a lot of knowledge about car audio, just the basics (I guess) Here's my current setup:

2- 10" Kicker CV-R, Amp Performance Teknique 1000w
2- 6x9 Pionner 5-way TS-A6992
2- 6.5 Performance Teknique

all 4 speakers Amp by Audiofonics:

I don't know if I should keep using Coaxial or Move into Component, will this amp be ok for some Decent component speakers, if so will you suggest a good set of them, I'm planning to spend around $200. All input will be appreciate it. Thanks!
