Hi GlassWolf -

At least in theory the BMW outputs are supposed to be balanced RCA's, and I did notice that when I disconnected the negative leads that my signal got significantly quieter...

Hi smoker / solacedagony -
I have to admit I've never heard of ferrite chokes. I assume you mean toroidal ferrite clamps - but what do they do, and which wires would they go on? And where?

Thanks guys - really!!!

Hi solacedagony, Yes, the RCA's do go near the nav system, but the noise doesn't go away when I change the location of the nav or the RCA's. Obviously I can't move either of them more than a foot or so, but I would think that should be sufficient to make the noise go away. Both pieces are in the sto...

Hi SolaceDAgony - I originally thought ground loop too, but the speaker wires themselves are all twisted pair, so it is unlikely that I am getting noise from the speaker wire. I tried Ground Loop Isolators - no effect. I'm no expert, so please take this as the question that it is: Can it still be a ...

Hi all, After resolving my issue with feedback in my rca's, I have tracked down and am trying to fix a new issue: Power Line Noise. The issue seems to be my factory nav system. For reference, it is a 2002 BMW 5 series. The issue is that my nav system introduces a whine and some static into my stereo...

As an update, I installed a Ground Loop Isolator between the 2 amps. Since this resolved the issue, I'm guessing there must have been some type of feedback getting into the RCA's between the 2 amps.

Can anyone please recommend a reputable amplifier repair / refurb shop that can do a once over on a pair of MTX Blue Thunder amplifiers? I prefer Northeast, but more importantly, I demand high quality/reliable work...

Thanks!

Hi Glasswolf, I am trying to power 4 sets of components and a pair of subs. The 504 provides 50watts to each of the components and the 3002 provides 300 to each sub. I have an electronic MTX crossover I could use, but I have crossovers built into the amps and therefore didn't leave a space in which ...

Not yet since I want to diagnose the underlying issue - I am completely positive that that will work, but I'm also positive I will lose my fader control :)

Y-cables it is until I can solve the issue!
