Great product, easy to install

Crutchfield Customer Review (What's this?)

This is a great product - comes with everything you need. Only problem I have found, which could just be opeator error, is that the bracket where the fuse is held somehow got complete stuck in the center plastic piece. I am not sure how it happened - but now I am unable to screw both sides of the fuse casing because one end of the fuse hangs out too far. This is now being fixed by using electrical tape to secure the fuse and that seems to work fine. Other than that, its a great product and very easy to install.

Crutchfield Customer Review (What's this?)

This wiring kit worked great with no problems to wire up my JL 500/1 amp.

not complete

Crutchfield Customer Review (What's this?)

I purchased this kit to install an amp in my trunk of a 2000 camry. Everything went smoothly, wires were long enough and conections up front were great. My complaint would be there was nothing for me to connect the wires to the amp???? I had to purchase my own connectors. Other amp wiring kits come with connectors. I thought to be a complete kit it would have come with connectors for the ground and power wire to connect to the amp. Not a complete kit......

This kit had everything i needed for my first amp/sub hookup. Its also a great kit for what you pay for too. I had more than enough wireing to go through my whole 95' eclipse. I recommend this kit for everyone.

Everything you need in one package!

Written By Sean, Hagerstown, MD on Tuesday, April 11, 2006

I bought this kit to install my 2x10in RF Punch S1s and RF 3001 amp in the trunk of my Mark VIII, and have been very happy with it. Having never installed an amp in the car before I was very pleased(and lucky) that everything I needed to correctly hook up the subs was included. This package is part of RF's Power line, which is their middle product line, and has very good components in just the right quantities. The cables were long enough (quite a feat in a car as long as the Mark VIII), high quality, and were the correct sizes for my application. A great choice.
