I just installed 2 new sets of components (4 6.5s and 4 tweeters for some reason people dont get this). When I have my volume low they sound fine, but when I turn it up about half to 3/4 they cut out (Like the "s" and "t" in words). Do I just need to let them get broken in or what? if it is just break in, how long or how will i know other than just testing them. They are power acoustik CPT-60c.
