Actually seems to be about 6 gauge wiring, but honestly the power and ground seem really nice, and also are easy to bend and work with especially considering it's cheaper than almost any 8 gauge kit. Fuse holder was also up to par. The RCAs however are junk. They are not anything similar to the ones in the picture and I'm going to have to replace them because even running them down the opposite side of the car from the pwr/ground/turn-on they are still picking up a large amount of noise. That's actually the reason I picked this kit was for the included 4-channel RCAs. Live and learn I guess. Also the turn-on lead was extremely thin, be careful with it.

The power wire has 583 strands that are 0.006" thick, which makes it 7.0 gage. The speaker wire has 50 strands that are 0.006" thick, which works out to 17.6 gauge. Both the power wires and speaker wires are copper clad aluminum, not 100% oxygen free copper.

I'm still going to use it, but am sad that the wire is not all copper.

Not really 4 Gauge as it says, probably 8 realistically. But over all great if you want an 8 Gauge kit for a good price.

This is just what you pay for, cheap price, crap quality. Speaker wire could be used as thread. Ok for what you pay for i guess but if you need 4 Ga, dont buy this.

I would recommend for low-powered systems as it's really just 8awg wire.

This is a terrible kit. The 4-Gauge power wire is way too thick and stiff, so it can't be easily routed. I ended up using an 8-gauge wire instead. Unfortunately I can't return this now since I cut up the wires while trying to install it.

The kit came with everything I needed to install my amp. Easy to use and everything looked great after it was installed. Looked at many other kits, but this one was by far the best value.

I cannot believe how crappy this stuff is I swear if you dropped the power wire it would shatter! all this kit is absolute garbage... pay more and get a better kit! seriously. cause now I have to purchase another kit and throw this all away... sad story but live and learn I guess

It's got thick plastic and not a lot of wire in the middle. This is 8 gauge wire. couldn't use because its too cheap.

Wiring kit was good enough to drive a thirsty 12" Audiobahn.

This is a great product for wiring 4 channel amplifiers. I used it to wire the amplifier in my 2007 Mustang, and it works fine. The quality is good, and the price is very competitive. I recommend this kit.

I ordered the 4 gauge kit actual wire was that of 8 gauge and a lot of insulation. Luckily, I was just getting 4 gauge for overkill being that there was not much wire for power to flow through. Excellent for a single amp that only needs 8 gauge. A large amp. Buy something else!

It hooked up my 4 channel 360w amp. The wire looks like 4guage until you cut into it. Then it appears to be smaller when you actually see the copper. Its not 8ga small but it definitely has less copper wire than other kits I have used. All the accessories were decent. I used my own RCA's as they are higher quality. Cant beat the price but you could probably pay a little more and get better quality!

Great kit. The raptor does what it is supposed to do POWER. Very well.

Basic average quality kit. Used it to wire a 4ch Ppi amplifier. Had it for just over six months with no complaints.

Personally I found this kit to be suitable. The rubber coating had a good quality feel to me and all the other parts in the kit performed as I expected. Overall a good value.

I would recommend this kit for regular sound system upgrade.

It's more of a 8g then 4g and RCA not the greatest.

This product does exactly what you need it to do. Its easy to you use and has all the connections you need to hook up your amp. Only thing that i would buy that doesn't come with this kit that you might need is a wire crimp and small connections for your speakers.

Nice plenty of length.

Dont buy this. It is the cheapest wiring kit you could by. Really an 8 gauge kit.

A great 4awg wire set for not a ton of money. good quality and a good fuse block

Not bad for the price beat any thing at locale shop.

Pushes my hifonics 1200 Watt monoblock and JL w6. does the job well.

That product was good quality, and included everthing I needed for the job.

Good quality wiring. I recommend using a gold battery terminal, seems to work much better for me. Wiring is ample, but be sure to run from the front to the back or you may end up short like I did.

I have these hooked up to my L7 and MTX JH600 and for the price it was worth every penny

I used this with my 1000 watt Hifonics amp for a little while until I upgraded to Kicker wiring. There was definitely a big difference between the two. but for $25 compared to $115? This wire is amazing for the price. I wouldn't use this wire for more than a 600 watt setup, even though it says up to 1500 watts. And another thing, I'm using the 2 RCA's for my 4-channel amp and they seem to be doing pretty good. Would buy this again... if my setup was 600 watts or less..

This kit looks very nice until you receive it. The 4ga power wire is not sufficently thick enough. I would say the actual wire strand thickness is comparable to 10ga. The RCA's are very good quality as well as the rest of the kit.

This product was good along with the price. It would of cost me double at my local audio shop:)

The kit in all is an INSANELY great deal. Wires are all excellent quality. Only problem i have with it is that the fuse holder does not hold the fuse very tightly, i had to put a small piece of foil about 1/2"x1/2" folded twice on each side to get the desired fit.

Everything you need is in this kit. It's super cheap and extremely easy to install. Perfect for the price!

Have not had any problems with this kit at all works great! for the price you cant beat it would highly reccomend

I bought this kit to hook up my Hifonics ZXi40.4 Amp. It is only 320 Watts RMS so I know I over did it with the wire, but hey I into sound quality. That is exactly what you get with this kit. I believe it is Oxygen Free Copper (OFC) Wire power and ground. Also it is true AWG 4G wire. That being said, it is surprisingly very flexible. I ran it down the driver side door sill, fit perfect. The RCA's are perfect, very good sound quality. Obviously not Monster Cable RCA's, but for sure do the job. Remote wire is your basic 18 gauge wire. The speaker wire was infact true AWG 16G wire and sounds good compared to my Rocket Fish Speaker Wire. I have 4 door speakers in my truck so I had to get extra wire, but that was expected. A plus in this kit is it is for 4 channels so I didn't have to buy extra RCA's. Also the fuse is not cheap, it is very durable and in a hard ABS Plastic casing. The black split loom makes my install look like a proffesional did it. Not trying to brag, but I know my way around car audio so it does look quite nice anyways. Overall this is an awesome kit for the price. I paid more at the time, but like I said it was well worth it. I love Raptor products, they have never let me down.
