I took the wiring kit right out of its packaging and right away it laid out straight which is a huge plus when you are installing wiring. It came withe everything i needed and more it install my subs and amp. The only thing bad i could say about this kit is that the ground wiring was a little short for my liking but it still got the job done. But other wise this is a fantastic kit and I have tons of left over speaker wire for later projects

I was having problems with the existing wiring for my amp upgrade. I recently installed a Kicker ZX 650.4 and the wiring wasn't handling the power. well I ordered the CK4 wiring kit and solved the problems. Sonic gave me a great deal that i would have have to order piece by piece based my pocketbook. thanks sonic for the great deal and great service.

This is the best product in the market great look great sound kicker is the best.

This is a great product... comes with high quality wire and connectors and it looks cool too with the whole blue and black wiring look.... good heavy duty fuse is ready to take what ever your system can dish out and its nice because the wire moves how YOU WANT IT TOO... no more wiring stuck in the positron of the packaging... great product... highly recommend it.

Has everything you need but is kind of pricey. The wires are have a higher quality build than others such as the ones you would buy at Mom&Pop audio shops or other brands such as Rockford. This was enough for me to run 2 Amps (600x4, 6001), 2 Kicker L512 subs, and 2 sets of MB Quart components. The included fuse is very large (think size of a Twinkie).

** Up-date: The Allen fittings on the in-Line Fuse strips VERY EASILY! I applied light pressure while wrenching down the power line and it stripped. I'm dropping Durability rating down 2 notches.

good kit for the value. nice strong wires, looks good also. the best part is how well it bends and stays in the shape you bend it too. gets the power to the amp better than my last kit!

This kit is great, i have it connected with my MTX 81000d and a phoenix gold 12" in a fiber glass box, AND IT HITS SO SO HARD!!! great choice

This amp kis looks soooo tight. They are really easy to bend and use. Had some problems getting the power wire to stay in the inline fuse box. all around this is a great kit. i highly recommend it.
