This is the real deal. Before doing the big 3 I was having big voltage drop...I was going down to .9 wjich Iis very bad. Now I dont drop below tweleve. I advise if you have headlight dimming or big voltage drops. I will say do the big 3 (with good wire like this one) before spending alot of money on a h/o alternator

High quality
these are high quality cables. True OFC copper the connectors
Are on very secure and in case you have to shortin the cables for any reason they give you ring terminals to put on after the others are cut off. You will not be disappointed with these at all. I know I'm not and I can be very picky when It comes to car audio

Amazing
Didn't have to do anything other than attach the wires were they needed to be. After watching youtube videos of what was required for the big 3 upgrade, I found this kit to make things easier.

Definitely A Must Have
I purchased this kit along with a XS Power battery. definitely the best investment I've made in a while. my car runs better with a much better throttle response. my stereo system sound so much better and so much louder, and i have no dimming lights anymore when the bass hits.

Perfect product
The installation process was great i called and there was a 4 day delay for a call back but they were very helpful and even looked up the correct price in my area for the installation for me and sent an email after. This prodcut exceeds expectations and comes with everything you need for a big three upgrade minus a ratchet of corse. I highly reccomend it

Great product
The big3xs is a great kit because it comes pre-crimped with heat shrunk ends. This makes it really nice and the quality is top notch! The customer service at sonic electronix is always great. Good communication on status of parts.

Does the job
I bought this and had friend install when I upgraded sub amp to 1400rms. Not sure if I needed or not as o stall for both was done at same time. I did not want dimming or electrical issues so I took the safe route. No dimming at all on stack electrical plus this kit. The wire is thick! Like a garden hose. Quality stuff and the connections already attached made no crimping necessary.
