Features

  • Car Audio Signal Hi-Low Converter It converters car stereo's high audio signal(R+, R-, L+, L-, Ground) to low RCA signal(left & right channel).
  • Amplifier Modify Accessory This adapter is suitable for car stereos without RCA output to connect with the after-market amplifier. Although some amp has Hi-Low Convert function, we strongly recommend to have such an external converter to avoid the interference of the conversion inside the amp. Especially useful for CD radio stereo without Line Out port.
  • How to ConnectEasy to install: Green wire connect to the Left channel negative. Yellow wire connect to the Left channel positive. Gray wire connect to the Right channel negative. Purple wire connect to the Right channel positive. Black wire connect to Ground.
  • Product Dimensions Compact sized: 6.4 x 4.3 x2.5 cm/2.52 x 1.7 x 0.98 inch. The shell made by metal, reliable and strong.
  • Reliable ServiceReady to respond within a 24 hour time frame. 30-Day money back guarantee, 12 month replacement and lifetime Support.

  • I got my car stereo to play my sub
Very easy to install

  • Works great for a great price!
The converter feeds line level to a separate amp for speakers on the back deck. Easy control of volume and off/on.

  • Sounds amazing
No interference at all, easy to install and the quality feels great. I seen one guy who said it blew after the first day I want to point out that’s probably because he connected it wrong. I have a 500watt skar vd10 on 350watts and I haven’t had a single issue. Definitely recommend for cars that cost a arm and leg for a aftermarket head unit or Apple play system such as 2010 infinity g37xS. ... show more

  • Garbage, doesn't work
First of all, if your vehicle is newer and has short protection, it will not work. Once turned off and back on, your vehicle will cancel signal sent to the speakers you hook it up to. Secondly, when it does work, it's garbage. You can hear the road noise through it. Every bumb or tap on it, is audible through the system. I mean, it installs easily, just like any other but I recommend buying one that also has a 12v power source input and possibly a level adjustment. ... show more

  • Perfect
Absolutely perfect for your needs. I run a single w 300w 12” woofer, from a factory amp under the passenger seat. Got this piece professionally wired as I couldn’t find the right manual for my amp. No issues, no burnouts, sound quality is 9/10
