[QUOTE="SQBubble, post: 8654323, member: 566772"] Everything was working great until i switched my 4ch amplifier and completly forgot to disconnect the power line from the battery and i think i messed up something...not sure the cause though... now both my 4ch amplifiers make really weird noise and the really weird part is that my sub mute option on my kenwood x997 H.U. doesnt work anymore only WHEN RCAs ARE CONNECTED TO THE 4CH AMP... my REAR channel's xover gets applied to the SUBWOOFER amp instead of the REAR channel... so i disconnected the amp. and my sub amp pops when i turn off the car.... disconnecting the rca from the subwoofer amplifier made the pop go away ..the next day i tried the 4ch amplifier and it actually worked great as long as i dont turn on the engine or even go on contact ignition, if i do go on contact ignition it makes a really weird sound and its even worse when i turn on the engine, but all of these noise goes away when the RCA's are unplugged... im running my factory rear speakers off the head unit's amplifier right now and its working fine, no noise, no issues... does that mean its an isolated issue with the head-unit's RCA's preout that are messed up for sure? or could it be something else.. im really curious to understand how could this happen though ?..did i blew/shorted the RCAs or something in the headunit??
