A while back I had this issue where this awful glitching sound was coming from the speakers and there was an alternator whine behind it. I eventually bought new high quality Monster RCAs meant for car audio. That solved the problem entirely. Now a few months have gone by, and 2 days ago im driving, i turn my radio up after i pull out of my neighborhood onto a main road, and my speakers made this wicked loud POP, and they all went out. My subs were still working and so were my dash speakers. The dash ones are off the head unit so thats why they stayed on, and my subs are on their own amp, which was unaffected. I took off the back seat to check out my speaker amp, and the power light and the protect lights are both off, but the HF logo on the front is lit up indicating it is on, but not being provided power. I took it apart, and it seems as though that amp is fried. So i got one from my cousin out of his old car. Its a pretty nice Kenwood 4 channel even though its a little old. so i go to plug that in with the same existing speaker wire, power/ground wire, and remote wire, and RCAs and everything works great, until i start the engine. Now I'm back to where i was 3 f***ing months ago with this awful engine noise through the speakers. yes it decreases in volume if i lower the gain on the amp, but then my dash speakers are way louder and it sounds awful. I spent from 1030am to 530 pm today taking out every single wire of my audio system and reorganizing it because back when this first happened i thought it could be bad grounds or bad RCAs (which it may have been) or everyone saying the RCAs are too close to the power wires. now every moron tells me "hey make sure you run your power wires and RCAs on opposite sides of the car! thats def ur problem" but these idiots dont know that the charger battery is in the trunk. so the power wire literally travels like 4 feet from the trunk to the other end of the trunk haha. totally away from the RCAs. the closest they get is where they meet at opposite sides of the amp. Now i was going crazy thinking this could be the issue so i took out the RCAs and the head unit. i regrounded every single wire. the power to both amps, and the head unit ground. not solved. i routed the RCAs from the head unit, and made the wire go as far away as possible (outside of the car) from the power wires just to test to see if it would go away. NOPE. i tried making them closer to see if it got worse. literally no change. no matter how far the distance. i even brought out my old RCAs to see if maybe some sort of magical thing would happen. NOPE. I re organized my whole wire setup in the trunk way neater with the power wires and still no fix. I honestly dont even think a ground loop isolator would fix this problem. every video on youtube of people with alternator whine is nowhere near as obnoxious and loud and annoying as the noise i am experiencing. I am just so confused as to why it is back. I did a little research and this kind of thing happens with pioneer radios a lot where if the power wire is in before the RCAs, a pico fuse inside the head unit will blow and cause this with no fix. Well I have a kenwood DDX 419 and i found nothing on the matter with kenwoods. now this could have happened when my old amp blew, and the power was trying to come back on and caused a continuous popping cuz the amp was trying to come on over and over again. But i highly doubt this. The only thing I havent tried is getting new power and ground wires for the speaker amp. although I have no idea why that would fix this. I have literally tried everything except that.
So here are my questions.
1. Any idea wtf this is being caused by and whats a fix?
2. is this common in chargers? i assume it could have something to do with the canbus system.
3. (not a question) here are 2 videos i took earlier of it happening.
1st video. Engine on radio on amp on. this is after making a new ground for the head unit. (my last thing i tried.)
2nd video. only because i forgot to show in the first video what its like with the engine off and radio and amp on. NO NOISE! but as soon as the engine comes on. boom, noise again.
