I've been procrastinating to get help, but for awhile now my speakers having been making "crackling" noises. Specifically i've noticed at 200hz on my mids (which are hsk 165xl's) bought brand new and 2khz on the tweeters, I've turned down the frequency on both of these and the noise slightly goes away at high volumes, but I think my subs just drown out the noise mostly. The speakers are being pushed by a rockford t400-2 amp. I've tried turning the punch eq down all the way, most i'd have it up is to about 1/5 and I have the input turned about halfway. I used to have it hooked up to a pair of CDT HD 690 cf's and they'd also make the same crackling sound. It's most noticeable on the right side and even blew out the right tweeter. I have my stereos head unit eq on flat, high pass at 80hz same on the amp, the crossovers are set at 0db for the tweets. At this point I have no idea what's going on that could be causing a problem, I've checked the wiring (14g nvx silver twisted wires) all connections solid. Any ideas?
