At first, i called Sonic Electronix up and they recommended this for my 1200 brz hifonics amp. The package came with everything in it, and i went to a local audio shop to install it in my car. Since I don't know that much about speakers and whatnot, I just asked the guy to install it for me. He was trying to sell his own wires and told me that the wires I bought could catch on fire in my car. Since I didn't have any money, I refused and just told him to install my own wires. It's been like 6 months so far, and nothing is wrong with it. The wires may be cheap, but that doesn't mean that it can do the job! If you're looking for a good deal on a wiring set and don't know what to buy, this is your choice!
