Great Quality.

True 8 gauge wire. Using this for a Kenwood 8404 and it is powered perfectly.

Great Buy

The kit was perfect for powering the amp, it has consistently provided great power (through the past six months) and the cables still look strong.

Excellent Wire Quality

I have the full amp install kit of this, which features just some RCA cables and speaker wire. The quality of of the kit is very nice. It delivers a true "8 AWG" wire. Rockford Fosgate is the only producer for amp kits I will trust. The sleek design, and the maxed out potential of there kits is just stellar.
