I bought this kit in store for $100 to power my Alpine MRP-M500, 500 watt mono subwoofer amp. I love the look and quality of the power and ground wires. Very nice jacketing and pre-fitted terminals. It also included an unnecessary, 30ft of speaker cable that was also very nice in quality. Fuse holder is nice. My complaints are with the RCA signal/patch cables and the installation accessory's. The RCA's are a very low quality set, very cheap materials. They do the job but there is some signal interference and if you so much as bump one of the connectors, i'd imagine it'd break very easily. The zip ties included are very short and small and made of a plastic that breaks very easily (I broke one trying to remove it from the bunch). Also there are no power or ground wire terminals for the amp end of the wires, forcing me to make bare wire fit into my amp's terminals. I'd say this kit will get the job done but for $100 i'd expect a more complete set of terminals and better quality cable ties and certainly RCA's.
