ok so ive been lookin for speakers for while, and i jsut found these sony 6x9(X5V6930A) for $89.99 there 80rms, now i know there not the best but im only interested in spl, my amp for my speakers puts out 60rmsx2 so i had to find something above that and didnt want to spend to much so will my amp blow these speakers or are sonys power ratings for speakers pretty accurate?
