Okay, you might say, what do you expect for 5-6-7€... But at least they shouldn't mislead people by saying that this Kit can handle so many watts... In the photo from left to right, you can see first a genuine 8awg that a car audio shop installed for grounding, then in the middle a smaller one for the positive... Far right is the cable from the Kit... It's not even half the size of the genuine cables for this job.... The Kit's cables for ground and positive are the same gauge... Only the color changes.... So with a wago-type clamp you add from the red... Wrap it with black electrical tape to make it look like a negative and okay... The amplifiers I have are around 600w each and now they don't have such small cables.... I got them for a similar job but I will really think about what I will do.... It needs a lot of attention and monitoring.... If you have a small amplifier up to 500w I want to believe it will be reasonably okay... For anything bigger I wouldn't dare to use it... For branching with two amplifiers, not a chance!!! The Kit cable has more insulation than wire.... The 60A fuse that comes with the Kit is for up to 850-900watt with the car running... That is, about half of what they claim... Maybe a safer fuse would be around 30-40A max... Of course, it depends on what your amplifier draws... I wouldn't trust this Kit for more than 60A at all.... But if you dare, check after a while of playing music at relatively high volume if it gets hot.... Also, with such a small gauge, it might be worth checking for significant voltage drop from the battery to the back by measuring with a multimeter.... If you see the cable getting hot or the voltage dropping significantly, maybe limiting the amplifier's volume will help by reducing consumption... It's best to do the tests with the car running because with just battery voltage you might not get a clear result and you might stress the cables and the fuse more.... In any case, proceed with caution with this kit...
