## Description

desertcart.com: SoundBox ECK4v2, 4 Gauge Amp Kit - Complete Amplifier Install Wiring - 2500W : Electronics

Review: Excellent Amp Kit - Excellent kit,installed fast and more than enough for a large suv
Review: Good for for the money - CCA 4 AWG - Better than I expected. Used this to install a 4 channel amp on a drift car. The power wire is CCA (Copper Clad Aluminum) which for this application was great because I didn't need a ton of power and it only weighs about 1.5 lbs (easily 10 lbs if pure copper). Fuse is kinda cheap but it does the job. Speaker wire is CCA so that should probably just go in the bin but even without that it's still a good deal. I wouldn't use this on a high end install but this kit definitely has its place and I was happy with my purchase.

## Questions & Answers

**Q: Why does it say it comes with 12 gauge speaker wire when mince came with 16 awg. Kinda pointless when you are trying to push a 1500 watt rms sub.**
A: I don't remember if it gave you an option or not sometimes on Amazon when you go to click on something there's different options you could choose I don't know why though cuz I got the same kit and I was able to get the 12 gauge that's something that the company is going to have to answer I don't have an answer for it really

**Q: Is there enough wire in this for two subs to the amp?**
A: Yes, theres enough speaker wire for 2 subs! However if your running 2 amplifiers no, you'd need a distro block or 2 amp wiring kits.

**Q: Oxygen free cable?**
A: My guess is because of the price no I was just looking for something to get me by that I could afford at the moment and they work great so but I don't know if they're oxygen free or not I doubt it

**Q: Not 4 gauge wire**
A: No it ain't 4 gauge wire
