If you need it for amp installation then forget it! the power wire is pretty thin and the whole package is kind of awkward… they should have included some extra terminals as well as given a better fuse box instead of ummmmm i’m not even sure how to call that FUSE box LOL. I got this set for hooking up my crossover so i don’t regret buying it coz it was only 7 bux. It’s perfect for what i need…Once again, i bought another amp kit from the amazon for 12 bux by boss and that kit is alot better than this 1 so if you need this 1 for amp installation you might want to reconsider your purchase.In conclusion, don’t let the price tag fool you, add another few dollars and buy a better product.
