Review on High-Low Converter 4-Channel Car Stereo Audio Speaker Delay Signal for Auto Amp, Subwoofer Amplifier, CD Player - High to Low Adapter by Kim Mills

First, the product I received is different from the picture, which may be the reason the wiring was 99,100% wrong. Power Wire - When connecting this, connect the black wire to ground, the red wire to battery power (not the battery) and the yellow wire to nothing. match what the device itself says. After installing everything I had to rip everything back to fix it because the left front is coming out of the right back and is confused in a way but imaginary. HOWEVER after the initial install on a cheap android radio hooked up to my 4 channel amp it works really well! 5 stars all day if wiring wasn't a problem. But now I've fixed your problems so you can buy it and install it properly and give it 5 stars, I. Not much - I had to do everything for you by trial and error.
