Our take on the Rockford Fosgate RFK10i

This wiring kit does not include speaker wire, so you'll need to purchase that separately to complete your amp installation. This kit includes patch cables for a 2-channel or mono amp — you'll need to add cables for multi-channel amps.

Your amp needs big power wires in order to deliver top performance to your sound system. Rockford Fosgate's RFK10i amplifier power and signal wiring kit supplies everything you'll need to send power and input signals to amplifiers with fuse ratings of up to 25 amperes. Rockford Fosgate makes the 10-gauge cable from 100% pure crystal-oxygen free copper wire so you can count on maximum power transfer.

Excellent product package - everything I needed for my package subwoofer install.

You buy a power amplifier for great sound, so why would you scrimp on something that gives you the power you need to make that great sound. That would be "penny wise" and "dollar foolish." [ John  Dec 25, 2015 ]

4 questions already asked

I always connect the color (red, black) to be the right channel. Letting red always to be the default choice. [ RAMON  Oct 11, 2015 ]
he black wire is a ground for an amplifier. [ SCOTT  Oct 11, 2015 ]
What matters is that they match on the head unit and amp - if you connect the black cable to the red output on the head unit, make sure it is connected to the red input on the amp. [ Bret  Oct 11, 2015 ]
It doesn't matter which you use as long as it's the same on both sides. So if you use black for right channel on headunit, then use black for right channel on amp as well. [ DANIEL  Oct 11, 2015 ]
Red is right and black is left [ AUSTIN  Oct 11, 2015 ]
Doesn't matter as long as you do same on both ends. [ Bernard  Oct 11, 2015 ]
Black goes to right [ MARSHALL  Oct 11, 2015 ]

Yea, I was hoping it was weather resistant / proof [ Rob  Mar 16, 2014 ]
I'd keep it inside the interior so it's not exposed to water and short out. It's a bit more work, but you'll have piece of mind. Good luck! [ JERRY  Mar 14, 2014 ]
