99 problems and a ground loop might be 1 and 2?

[Volvo_S80]

After a very long wait from winter and saving I finally got to hear my system today and //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif all smiles I rushed it because i had somewhere to be and on that hour+ ride all seemed great but I hadn't set my gains on anything just kept it low. So I got Home and set my gains using the clipping sensor for my sub on the DD bass knob and set the front tweeters and 6.5 to loudest un-distorted and then boom I get a whine that goes with my Engine RPM's and a kind of white noise thats just there when the volume is all the way down and you can hear it at very low levels of volume and to top it off I get a turn off pop light and not too loud but a pop.

Here's the equipment

2008 Volvo S80

JBL MS-8

Zed Leviathan III

DD M2C

Sound qubed 6.5 pro's

CDT T-28

DD 3515

Knu Krystal Kable's

Everything is mounted to MDF

I have 2 1/0 power running from Battery to a distro block in the trunk and split from there

My ground is an existing bolt hole I know you guys frown on this but it seemed to be a very heavy metal spot and so i went with it.

I have a 1/0 ground from my battery to that bolt hole with all equipment grounds as well because I didn't want issues //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif so that didn't work.... and a new ground from battery to the Factory grounding spot.

All the Equipment is in the trunk close together So no long runs of RCA and the RCA's are not near the power.

The speaker wires from the Leviathan to the right side are close to the power wire runs but the noise and while are in all speakers.

No rear speakers at all

I had to cut the speaker wires coming from my factory amp (front right and front left) to get the signal to my MS-8 these wires are also fairly close to my 1/0 power runs Sky high 1/0 and NVX 16g

the remote turn on is from the fuse panel in my trunk that only turns on when the car is started :/ couldn't find an accessory power but will look better (in the front) and go from there.

That about sums up the install hopefully you guys have some ideas. I have a long weekend so I have plenty of time to re-do whatever is needed.

Tweeters crossed at 2500

Mids at 70

Sub at 80

sounds decent I still have to play with it. The MS-8 does't make messing with the x-over easy at all.

Voltage is good too BTW that was a concern of mine and some on the forum max gain with the clipping light blinking rapidly showed 12.5 at the lowest I've seen but hangs around 13.2 13.3 and it's at 13.5 with no volume

Well you know what to do. Start trying to isolate the source of the whine. I hate "the whine", such a headache. I usually get the low hum.

 

[Volvo_S80]

Yea I'm doing some research now. I'm just going to take it all out and put it back in again and not go the lazy route and find a better ground.

 

[Volvo_S80]

Ok I got the whine out by making a new ground for the M2C so the MS-8 the zed and the battery ground share a spot and the M2c is all alone but there is still a faint static noise when the volume is off and you can still hear it as you progress upwards in volume, even at max i feel like i can hear it when the bass isn't rattling my brain lol

 

[Volvo_S80]

The faint static was my gain setting too high. The pop from shutdown is still a mystery I'm betting it's my remote power.

I can't believe only one other person has commented on your thread! I am glad you were able to isolate one problem, and I hope you are able to find he popping noise too. I saw "Zed Leviathan" and immediately thought, "it should be so clear and quiet in there, he should be able to hear me breathing down here in Mississippi. I can say one thing though //content.invisioncic.com/y282845/emoticons/needpics.gif.edd6d28e76618c28c46f343991bcced5.gif

Pop up some pics, I would love to see what you're running!

 

[noble brown]

Yeah never had to deal w the turn on pop. I do know that you can tackle that w a relay.

I'm thinking finish it off with a false floor and I'm debating weather or not to add Plexigllass to show the zed or keep it hidden.

So I have been messing around with the MS-8 with the acoustic measurements probably about 25+ times and there's more to come for sure lol but my overall satisfaction is a toss up honestly I mean I have gotten it to sound great and the sound Imaging is crazy It really makes the music sound like its coming from the windshield and that's something I've never experienced before BUT I wish it was louder. I keep messing with the gains and the crossovers on the zed amp to try and get louder but I keep getting distortion. I can't seem to get it as loud as i want while staying great sounding. I'm going to mess with it more naturally but I'm thinking maybe my speakers just can't do what I want?

Edit: The faint hiss pretty much goes away when i turn the gain all the way down. again this doesn't help my itch for loud
