I'm still struggling with my install. Here's what I have
Stock head unit
Fiber Optic to factory amp
Line level from factory amp to JBL MS-8
RCA's (Knu) from MS-8 to Zed Leviathan III and to DD M2C
All Sky high power and ground
I've had a hard time the whole install but have learned quite a bit as well. I had some engine whine and a hissing noise I figured out the whine and settled with the hiss. One day I cracked and decided to find the hiss, I went straight for the MS-8 and hooked it up right to the speakers not using any of my amps so they were powered by the internal amp on the MS-8. The noise was not as loud but still there. So I sent the MS-8 in to be replaced.
After a long wait it's install time again. I hooked everything back up again do my first acoustic measurement, unplug the mic, press done....... and hisssssss once again. So I start trying to isolate the sound once again. First I unplug the RCA's from my zed and plug shorted RCA's the hiss is nearly gone but I can still hear a faint something not sure if this is from my seriously low quality shorted RCA's or something else. The noise is not loud or intrusive, when I have the car running you can't hear it. So I don't know if i'm being over sensitive or not.
I flipped back and forth between the shorted RCA's and the RCA's coming from the MS-8, the MS-8 RCA's are much louder for sure. So I took the RCA's out from there tucked in location and spread them out so they were dangling outside of the trunk, no change in the noise at all.
Next I decided to try and ground the RCA's and that was a horrible idea. It was very noisy to say the least. After that I removed the line level input to the MS-8 and still the noise was there. So I go to home depot and buy a multi meter to test the resistance between my battery and grounds I used some spare wire I had and connected it to my battery terminal and walked it over to the trunk everything tested 0.0 . So then I decided to run a power wire outside of my car to the MS-8 and zed. Still the noise remains.
The Zed with shorted RCA's creates very little noise (the least) but still noise and I'm not satisfied with it.
The MS-8 makes noise being used as the sole amp. It's quieter for sure the 2nd quietest overall
The MS-8 and zed used together creates the most noise. It does get louder when I turn the gains up, but from the about 1.4 mark down (1/2 way) it stays the same, The loudest.
This is my 2nd MS-8 and it's still noisy. What do I do next? Is it possible my car is responsible? 2008 Volvo S80 T6
The noise from the MS-8 is too loud to just deal with considering the amount of money spent. But am I being oversensitive about the Zed? it's slight but noise is noise. Any tips are appreciated.
