I don’t think my setup is right,
I need to know how to wire my subwoofer to 2-ohm?
It’s one JL 12W3-D4 subwoofer
And who to connect it do my Amp. Since it’s a 2 channel Amp.

Is your sub a single or dual voice coil speaker? What ohm is each voice coil rated at?

EDIT: looked it up: dual 4 ohm.

Im not sure about the amp, but if you just add a jumper from the positive on one side of the spesker to the other positive, and do the same with the neg, you will have a 2 ohm speaker. then just run your wires from one set of terminals to the amp. Most amps will have a + and a - for bridged mode. I have to get back to work now. but i'll draw a diagram later.

its a dual coil speaker, and i dont know what the coils rate are
I did a little diagram... is this the right way?

the stock speakera are 10ohm right, so lower = better?

Yeah that is the right way. If you want you can run both wires that go to the amp from the same side of the speaker.

Not exactly. In most cases if you lower the speaker resistance, the amp will put out more power to the speakers. The drawback is more heat. The average amp is only stable to 2 ohms, but some can be dropped as low as .5 ohms. If you overload the amp, it can cut off or just plain burn up. Its just like building an engine, figure out the power that you plan on making and match the speakers to the amp.
Im not sure what the stock speakers are, OEMs are sometimes higher than usual. Most aftermarket speakers are 4 ohm, but you can get them in 2, 4,or 8, with single or dual voice coils. When you hook up a DVC (dual voice coil) speaker, its just like hooking up two speakers.
