[QUOTE="Thunderturkey96, post: 8704662, member: 679615"] So I just got done doing a bi- amp set up in my 95 ford thunderbird. I have a 80prs radio, a kenwood X-542 amp on Audison Voce components for mids and highs. I’m using the crossovers in-line on tweeters, and I have a crescendo bc2000d @ 2 ohm on a Rockford T1 sub. The problem I’m having is I have a constant high pitch noise that only comes through the tweeters I cannot figure out. I had coaxial speakers in place of the mid woofer and even those tweeters where doing it since then have put in the Audison mid which has no tweeter obviously. So far I have ran new rca’s made no difference, turned gains way down to see if maybe that was the culprit made no difference, tried grounding rca’s on back of radio, made new hum so promptly removed it went back to how it was. The weird thing is it’s more noticeable when the car is cold after the system has been on for awhile is gets a lot quieter till it’s almost inaudible but still there. The noise also doesn’t change with rpm and even makes it when the engine is off Completely. I also tried a different radio I had lying around and that also made no difference as well, and besides this issue the system sounds amazing..... Any ideas??? [/QUOTE]
