Review on 🔌 PAC Amppro4 Ford Sony 2013-2017 Power Adapter - AP4FD21: Amplify Your Ford Sony Audio System with this Easy-to-Install Adapter by Luckie Davidson

is convenient and easy to install instead of searching and splicing millions of wires for all the speakers, but adds some noise to the signal even when the main unit is off and not playing music . I tried many things and I could find that the problem comes from this device. The hiss isn't always noticeable in the mids as road noise is above it, but the hiss from the tweeters is still clearly audible and now that I plan on soundproofing and isolating my entire car I hear the hiss much more clearly. I was expecting this to be a premium product since I paid such a premium price for it, but unfortunately it isn't. I bought it from Walmart's online store.
