As you can see, one is thicker (4awg) and the other is thinner but suposedly got more quality, plut it brings 20feet speaker cable against 10feet from the KLM. Both of them costs the same price, so its a case of which is best for me.
INFO on my Project:
I'll install the kit on a 360 watts rms 4-Channel amplifier on my car.
On the amp, I'm gonna put a 180 watts rms subwoofer on 2 of the channels (bridge), and on the other channel, I'll put a 70 watts rms kevlat two way kit.
