This amp install kit is NOT 4 guage. The outer diameter of the wire insullation is equal to 4 guage, but the power/ ground wire is actually only 10 guage. The small print is on the packaging stating this fact. Do not purchase this kit if you need anything bigger than 10 guage. The RCA cables were a good quality. All connectors were cheap but usable. The speaker wire was TINY, too small to be used, I threw it in the trash. I am not saying this kit wont work, b/c I did manage to make do with it, but I would not recommend it to anyone.

Good kit, The RCA's were plenty long and seem to be just as good as anything else I have ever used. Comes with everything you need. 4 awg kit for this cheap is a steal.

1-iTS NOT A PHOENIX BRAND ,ITS PHONICS AND FOR THAT MONEY I CAN GET BETTER QUALITY ,THE ONLY USABLE THING WAS THE RED POSITIVE CABLE THAT HOOKS TO THE BATTERY

This kit gives you what you need but I agree with another reviewer, the speaker wire is too small. I used some other wire that I had. The rest of the kit is a little cheap but you get what you pay for and the kit really does the job. The ground was long enough for what I needed and the rca cables were long enough and pretty good quality. The connectors for the "hot" wire and the ground were cheap so I used ones I already had but The kit worked for me

This was a good product for a good price. There was more than enough power wiring to run anywhere I wanted. The ground wire was a little short, but was able to make it work. long rca's and remote wiring work good. Good fuse. Very happy, would buy again for my next project.
