About the EFX 4-Channel RCA Patch Cables

Make reliable connections

These 4-channel RCA patch cables from EFX will send your signal cleanly across the field of induced noise and uncertain factory electronics in your car, so you'll hear all of your music with none of the noise. EFX RCA cables resist noise due to their shielded construction and the twisted-pair arrangement of the wire inside their jackets. The cables also feature a single-molded jacket for better flexibility and reduced diameter, and their multi-gauge conductor core enhances frequency response and clarity. Warranty: 1 year.

With this install, I actually want to take advantage of the RCA outputs on the back of my new head unit to get the cleanest sound to the amp in my trunk. The amp has line-level inputs, but I'm hoping this will give me better sound, and I just prefer the "cleanliness" of this method. [ Luke  Jul 09, 2017 ]

Q
What gauge is this cable? I'm told I need 4-gauge for a Kenwood head unit to the amp in the trunk, will this work?
[ TrueJedi  Feb 08, 2017 ]

Well it will work but y do u need 4ga? What amp are you using and how many watts are you pushing?
[ David  Feb 10, 2017 ]
A
Yes
[ robert  Feb 09, 2017 ]
A
This cable will send audio signal from your head unit to your amplifier. Example, front l&r and rear l&r. The 4ga wire your speaking of would run from your battery + to your amp.
