🔌 SoundBox 4-Gauge OFC AWG Amp Install Kit: Complete Oxygen-Free Copper Amplifier Wiring Review

Everything is exactly as described. Real copper and really 4 gauge. The fuse holder is of good quality. RCA are good. The speaker cable is very good. My only criticism would be the pin size for the crimp connectors. It would be nice if they included larger ones.

Prior to this kit I used an aluminum clad power cord on a 2400w Fosgate amplifier. I started having problems with the wire heating up and the insulation melting. I switched to this kit and haven't had any issues since, the bass is clear and the wire stays nice and cool. Excellent quality and the right size for what it appreciates.

The power and ground wires are of high quality and good insulation. Both cords are long enough, and in fact the ground wire is much longer than what is needed or what is typically included in these kits. RCAs are very thin and cheap. I went with a higher quality kit and would recommend this if you want better sound quality. The fuse holder feels solid and looks decent. I think this is a great set for $.

Pretty good amp set for the money. Similar products (go to Crutchfield and type copper amp kits) cost over $60 more for the same thing. This is true AWG 4G, it really delivers tremendous performance and amazing quality. The cables are soft to the touch, even the audio cable is good quality BUT THE POS CABLE IS NOT COPPER, appears to be aluminum but works on the alpine Mrv-m500 with 10 kickers and sounds fantastic. Don't doubt. If you've read this far, BUY IT. So worth the money.

Excellent packaging for the price. True 4 AWG oxygen free copper wire as opposed to the kits which cost $20 less and claim the same gauge and oxygen free copper which is a complete lie. I put an RCA next to an RCA Rockford Fosgate and they are identical, I wouldn't be surprised if the RF was just renamed. Even the speaker wire and remote control wire are the right size/length and have a textured (not shiny/tacky) finish which actually makes sense for a car audio installation, unlike the wires…

I ordered a 4 gauge wire harness in January 2020. It is now August 2020 and it is not working. The woman told me her sub stopped working. So I started testing everything. I got to the 12v power wire and pulled the fuse out thinking it was my problem. The fuse is well checked. The wire was stiff from the fuse to 6 inches towards the battery. I cut it open and found everything was rusty and broken into pieces. When I installed this I used whatever came with it so everything should be fine. It…
