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.

Customer Testimonial

Sonic Electronix is the best! Ordered an LG 50" television online and received it in perfect condition in one week. Then entire buying process was perfect, from the ease of the initial order, to the order tracking information, to the delivery. Fantastic experience - highly recommend.
