Greater than one weekThis kit has everything you need to properly install an amplifier. The only thing I would have to ask for, would be that they increase the length of the power wire. As with most other kits, this one provides 17ft of power wire. Now if youre lucky, as I am, and have a coupe... then you will have JUST ENOUGH to work with... after running it up-down-and-around everything, in order to make it all the way to the trunk. If you have a sedan, you may want to mount your amp in a different location, as it may not be enough. Overall, I give it 4-out-of-5 stars for this reason alone... if the power wire was 20ft, it would have been 5 stars all the way.

> 3 dayInstalled this myself in my 2013 Toyota Corolla Sport Special Edition. Love it! The cords are very good quality and I like the fuse. Very nice. I would recommend this to a friend

Greater than one weekThe kit is very complete. Is more than enough for amplifier of 2000 Watts. The cooper is thin and the insulator is made of great material. High quality!. The 100 Amps fuse receipt have one problem, is not possible to adjust the fuse once it is in possition. It may cause sparks by bad contact between the terminals and the fuse. But it isnot a big deal.

Greater than one weekMy Rockford R150 2 ch amp is hooked up with this kit. No problems or interference at all. This is a good kit to start with the first time. Dont ever cheap out on something you want to last and have quality with. Im glad i went with this kit and it has everything you need to hook that sub and amp up to get it running at home. This kit went into my civic with all the wires hidden and amp under the seat. There is easily enough to hook up the amp in the trunk or probably hook up another amp.

> 3 dayi love the wires and all the nicknacks they send you along with it. But the power cable could be a little short for the longer cars like an 03 montecarlo or your cadillac
