The 1M2F injected RCA Y cable is an excellent example of high quality, as are all RCA cables from Taramps. It has a pairs of twisted wires with two internal conductors, made of 99.99% OFHC copper (oxygen free) that guarantee low signal losses and is perfect for splitting the signal from an audio source to two amplifiers. The plug cover is injected in high quality plastic material that doesn’t degrade with the high internal temperatures of the vehicle. This type of cable is noise canceling thanks to the internal twisted wires. This technique gives the cable a more neutral impedance characteristic, allowing for more crystal clear highs. It also has an ultra compact and bicolor connector, one male plug and two female plugs. An indispensable accessory for a reliable installation.
