im looking to re upgrade my 6x9s right now i have some kicker ds6x9s and db something 6x9 in the back i was told their good speakers but on my alpine head unit they cant be turned up past 21 out of 35 without severe distortion any suggestions on good 6x9's i dont plan on running and amp to them atleast for now. i also read somewhere that speakers will distort if they dont haave enough power.. could this be the problem??
