Whine only from front left speaker output of amp

[disturbedfuel15 10+ year member]

Okay this is absolutely driving me nuts. I can not for the life of me figure it out. I used all the methods of cutting back engine whine in the stickied thread. I even grounded the head unit to two different bare pieces of metal on the frame.

Yesterday there was no whine, just a slight hiss which wasn't a big deal when the music was turned up a few notches. I forgot to install the tweeter attuntuation loop thing on the tweeters, so I turned around and wired that in there between the crossovers and the tweeters. Now a loud whine is coming from the front left tweeter and speaker. Here's the kicker, if I switch the RCAS around, it doesn't make a difference. I thought maybe it was the speaker wire, so I tried switching the left and right speaker wires coming from the amp. Nope, the whining just switches to the other side, so the way the left and right wires are ran are not to blame. It is LITERALLY just coming from the front left speaker output of the amplifier. The amp is a soundstream dtr4.500. Thanks in advance, this is BLOWING MY MIND.

its either the deck or amp has a bad internal ground

How would I go about testing this out? The deck and amp are both brand new. I don't understand why I didn't hear it yesterday and now today it is so loud.

try swapping out the amp first with a different one.also try grounding the left channel rca to the back of the deck and see if that helps

Just hooked up the back speakers, no sound at all coming from the back speakers. Gotta troubleshoot that now too. I never remembered an install being this big of a PITA

Okay I found out it has to do with my amp. I banged it around a few times and it is not making that sound any more. wtf? I guess the amp is ****. Someone on here sold me it, I'll have to see if that guy is still around. It very well could be that the rear speakers aren't working because the amp is just ****, like I said. We will see.
