Ok, so for the past 3 years ive never seen this... but i tested an amp oon my setup for my friend to kmake sure it worked before he bought it and it worked fine, i hooked up my amp for my system back up (Power rca and 1 sub....) all i used to test other amp and when i got back to mine ever since it got hooked back up the EXACT SAME its picking up this whine again.....i double checked everything to make sure wires arent cut\ or shorting out at terminals at all it still sounds loud and all at higher volume but when my volume is off you hear the subs putting with the exhaust...? any1 have any suggestions/? my HU RCA's go out again? i just got this HU a week or 2 ago when i exchanged my old one.... if it is that i got warranty so no biggie....
it could very well be that ur HU is bad again. i dont know why it would so fast but ur RCA's or somthin is messed up and pickin up interference. just a question, but r u runnin ur RCA's (from amp) with the power wire? -- like on the same side?
