Well boys and girls, the noise is finally gone. And while this fix is not up to my original standards, I am content and done with this project. Here's the story: I knew the AudioControl Matrix was intended to be placed as close as possible to the HU, but there simply is not enough room to put...

I have not personally. But many others have measured it with an oscilloscope, and have posted their results for all to see.

The factory TL HU puts out a perfectly clean signal all the way to max volume (no clipping). It just happens to be balanced, which apparently my amps do not like (despite the claims from Alpine).

High-Level inputs have nothing to do with frequency. It's referring to the high voltage of the signal. Everything is line-level (low voltage) when it comes out of the HU (pre-amp), and is then changed to high-level (high voltage) after it's amplified. It makes no sense to use the high-level...

Sorry, I don't agree. A LOC is used to REDUCE the voltage of an amplified signal to make it more acceptable for an aftermarket amp. The last thing my signal needs is to have its voltage reduced. I actually just ordered the AudioControl Matrix Plus to BOOST my signal even more before it gets to...

Did you guys read my last comment? The amps are not receiving a high level input. The signal coming out of my headunit (or any headunit) is not considered "high level". It's a pre-amp, low-voltage signal. The only reason I would need to use the speaker-level inputs is if I were taking the signal...

The amp does accept high level inputs, but I just soldered on RCAs from behind the factory HU because I would not consider 1 volt to be "High Level". If I were taking the signal after the factory amp, then yes, I would have used the High Level inputs.

That's the thing - I don't have a LOC! I have no processing from the HU to the amps, and I think that's my problem. However, I don't need a LOC (which reduces the voltage of a factory-amplified signal). My signal is coming from the factory HU which is already so low (1 volt at max volume). I...

I have tried bypassing the HU and plugging my iPhone into the amps via the same RCAs - the noise is gone when I do that. So that led me to believe that it was a HU issue. However, I bought another OEM HU and I had the same noise (worse actually). It seems unlikely that both OEM HUs are...

Hey guys, I'm trying to finish up a pretty extensive audio install on my 2004 Acura TL, but I cannot get rid of this horrendous alternator whine. And trust me, I've scoured the interwebs, trying to find a solution to my particular problem (I know alt. whine is a rather common one), but nothing...
