Hey, posted in two sections wasn't sure which one was right. Mod please delete the one in the wrong section. Just need this answered quick, thanks all.

So this is what I basically have.

A ZX650.4 4CH kicker amp, 650W RMS.

A front pair of kicker component speakers ks650.2 I think.


Now I have a JL W3v3-4ohm sub. Handles 250W RMS. The amp can put out 320W RMS. So no overheating which will be nice.


Anyways my amp/speakers are all set up. But I need help connecting the sub to the amp.
Heres my questions.
1. Do I set the sub on a Low Input Level, instead of a High Input Level?
2. Do I use a crossover switch on both the speakers and the sub? Or do I still let the speakers do the mid-bass.
3. What do I do with the fader switch? It says leave it depressed if im running two sets of inputs.


Thanks a lot.
