But you need to figure everything in RMS wattage. Not Peak. I have a SKAR 1200.1. 1200 watts RMS but it hits abt 2500 peak on the amp Dyno@1ohm. This kit is adequate for my setup. This kit is OFC. 2500 watts RMS no but if your amp is 2500 peak. Yes this is enough. Also depends if your amp is class B or a Class D amp. Class D Amps are abt 75% efficient Total RMS wattage divided by 0.75 then divided by 13.8 gives your total current draw of your amp. If you have a class A/B change that number to 0.50 and do the same calculation. A good rule of thumb. Take the fuse ratings on your amp and add them up. Multiply by 10 and that’s usually your real RMS not what is advertised on the amp. If it has no onboard fuse the owners manual will tell you the recommended fuse size and multiply that by 10. I’d say this 17 foot kit would be fine 1200-1500 Watts RMS. If it’s closer to 1500 watts just buy a 150 AMP fuse for this kit on amazon for 4-5$ and you should be good. Always rake distance into account too. 16-18ft of 4 gauge OFC is fine. But if you go over 18ft you need 2 gauge or 0 gauge. **Q: Will this run my Kicker 800rms amp?** A: no its just cable it won run it **Q: Is this an amp kit or a phone case holder because the picture shows a phone case but the description says it’s an amp kit** A: Amp kit, come with everything you need to hook up an amp. **Q: Will this kit run my 1800rms mono class D kicker amp?** A: Yes, it should. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Ever *by R***L on 16 November 2020* Best Tweeter ever, very clean sound and very powerful, rated power..
