Fixed Mazda/Bose issues
I recently added an aftermarket amp to my 2009 Mazdaspeed with bose. It goes without saying that bose stereos are garbage, and the signal from my stock HU to a new amp was problematic. I was getting terrible channel separation (fading fully to left or right I would still hear sound in the other channel). One of my amps had some isolation built in, but the other one didn't, and it put out horrible alternator noise. I bought a pair of Peripheral PGLI's and they fixed all the problems I had with this setup. My balance controls works like it should, and all that noise is gone. I know that people worry about loss of sound quality, but I have not been able to perceive any loss of fidelity with these installed. I strongly recommend this product, and you have little to lose with the price.
I wish the leads were a bit shorter, but the product is very solidly built. I did not have to use the brown wires; in fact when I did try them the noise came back.
