i bought this kit to hook up 2 alpine MRP series amplifiers with a 2 farad capacitor. The quality of the kit is very good conisidering the price. I was very impressed with the extra items included in this kit. The wire gauge was actually 4 gauge(as opposed to some other kits with 10 guage wire inside double-thick insulation) and there is a power and ground distribution block to separate the power out to multiple amps. The terminal end connectors included are a little cheesy(low quality, hard to install, not well insulated), i recommend getting some higher quality ones from a hardware store and adding your own shrink tubing for insulation, but other than that it's great.
