sq issue with rear speakers

[pegasis50 10+ year member]

How do you tell if your coax speakers are blown?

I have some new infinity 6.5 kappas that sound good at low to medium volumes, but at higher levels they sound "weird". No popping or anything, just less than optimum. They are in the rear deck for fill, and no fronts or subs are installed yet, so I hear only the coaxes.....

They are powered of off an Alpine PDX 4.100 amp (120 actual watts). Could they be overdriven, blown, or just poor sounding? They are OK until medium volume. How do you decide where the sound quality issues are originating?

this isnt an "SQ" issue.

if thats all you have, no front stage, move them to the front. your sound stage should not be behind you, period.

But regardless of where they are at they should be "clean".....correct?

I have some components and subs to be installed next week. I was just trying to tune the rears w/o any other noise, to set the crossovers and such properly.

Ideas?
