Great wire, terminators could be better.

John from Monrovia, MD on 3/14/2025

1994 Ford Mustang

Verified customer (What's this?)
Verified employee review (What's this?)

This is some heavy duty wire! I'm impressed with the quality of the wire and insulation, but I ended up replacing the ring terminal at the end. The battery terminal connectors that I have are 3/8" and the rings are only 5/16". Also, the rubber sleeve at the end is loose and would not have stayed in place. I replaced the ring terminal with marine rated tinned copper lugs and used heat shrink tubing to finish it off. It would also have been nice to have a little extra black wire since I needed 3 ft. to ground the amp in the trunk and also another foot to add a heavy duty ground on the battery-frame side. The stock ground wire on most cars is only 12 or 14 gauge.

Pros: Good quality wire with thick insulation. Reasonably priced

Cons: Rubber boot does not fit tightly and will slip out of position. Could use a little more black wire. Ring terminals a little small for such big wire.

Excellent kit

Chane from Medley, FL on 3/6/2025

Verified employee review (What's this?)

True OFC. High quality wiring. Very flexible and easy to route. No issues with wiring to amplifier. External coating is nice and stain resistant as my hands got pretty dirty while routing under hood. Dirt either didn't stick or wiped off easily. Ran my RCAs along side it even though its not recommended and got no crossover or inducted noise.

Pros: High Quality Flexibility Easy to route

Cons: None

Good wire. Fuse block wasn't the right size

Chris from BRANDON, MS on 6/20/2024

2024 GMC Sierra 1500

Verified customer (What's this?)
Verified employee review (What's this?)

Good quality wire. Enough length to run from battery to the back cab wall in a 24 Sierra crew cab. The fuse holder didn't accept 1/0 wire on either end. The holes were slightly larger than 4awg. I had to buy a 1/0 fuse block locally. It's still a decent value just for the wire, but was disappointed when I realized that I needed a proper fuse block. Would've been 5 stars if the fuse block was the correct size.

Pros: Good wire

Cons: Fuse block didn't accept 1/0

Verified employee review (What's this?)

I haven't used my wiring kit yet,but Crutchfield always has top quality stuff ,I especially like the lifetime support on their products,on a previous Mustang I wired in 3 California amps: one for my bazooka sub,one for the rear speakers,and one for the front speakers. I'm still acquiring all the parts and pieces for my latest Stang project. ,due to the wattage I want I have a 150 watt rms kicker for my 10" bazooka sub, a Jl audio 4 ch. 70 watts for my rear and front 6.5" speakers,and the last amp I have to buy yet,a Kenwood 4ch. 50 watts rms for the mids and tweeters all that will run thru a Audio Control 8ch. line out converter.I highly recommend Crutchfield their staff are knowledgeable and friendly. Summed up Great gear,Great people

Pros:

Cons: Only con is that I couldn't get all 3 Amps in same brand at the price I could afford,with the hookups I wanted ,not a problem tho,I know my system will sound great!

Name brand quality, store brand cost.

Chris from Apison, TN on 2/23/2024

Verified customer (What's this?)
Verified employee review (What's this?)

Very good quality regardless of brand. Typically, we think of in-house brands as being sub-par but the wire, fuse holder, and everything in this kit is top quality. Extremely flexible even with the large wire size. This was a choice to have red wire in a red vehicle but I feel like the quality is up there with any name brand kit I have ever used.

Excellent amp wiring kit. Impressed with how much copper this kit has. Thick wire sheathing for both power and ground wires. Fuse box with dual fuses is also very good quality. Wished the kit came with ferules and heat shrink.

Pros: OFC copper wires Ring terminal connectors pre-crimped on one side of power and ground wires

Cons: No ferules and heat shrink

Verified employee review (What's this?)

I spent hours looking at audio manufacturer options, online stores. After reading so many poor reviews from other brands I decided to go with these. I gotta say they are HEAVY duty. They weigh a ton and it's 100% copper wiring. There's thousands of threads and they're super thick (especially the copper). I still have to install them but I can tell they're going to bump. I would highly recommend these. I was skeptical at first because there aren't a lot of reviews so I came in here to try and help the next person.

I had worried I would have to get a hydraulic crimper to crimp the end that connects to the battery and ground, but to my surprise it was already done! It has my 1500 watt RMS system bumping and couldn't be happier. It's true 1/0 awg 0 gauge and ofc. Thank God I went with this company than any other. Thank you!

Pros: No need to crimp True ofc Plenty of power

Cons: None

I'm really impressed by the over all quality of this kit. What really caught my eye was the inline fuse tho. It looks great along with strong quality construction not cheap plastics would give 10 stars if I could. If you guys are looking to pull a lot of power this kit can take it I am running a CVX kicker 15in pulling 1300 watts rms in a ported box and it's perfect
