Worked great for me

I got this to use to install the amp on my 2011 Ultra Classic. The kit had everything I needed and worked great. It was a Soundstream amp and the wires were a perfect fit. I would definitely recommend this kit to anyone installing an amp. Worked for me.

Not true 4 gauge, more like 6 or 8

I would not recommend this product if you are looking for true 4 gauge wiring. It did come with everything needed.

Great cables

Really good kit. I like how the wires feel and everything is already crimped.
