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.

Size: Audio Adapter
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
