4 ohm cvr or 2 ohm cvr? What's the difference? How to wire at 2/4 ohm? Help

Something tells me 2 15s won't work in a IS300 if that's your car and CVRs may not be your best choice.
But 2 ohm vs 4 ohm just helps u match up to your amps required impedance for the power u need. What Brutus amp do u have? They are 1 ohm stable so you'll need dual 4s and need to wire them to 1 ohm.

Use this: Rockford Fosgate® - Woofer WiringWizard
Sorry, I didn't see your post but I have everything in the car already and it fits and thanks for the link. But when I'm wiring to 1 ohm do I have to wire it to the terminal on my box or straight to the sub?? Thanks

Wire them to the terminals on the box then run a wire from the pos on the amp to pos on box and same for neg.

Fitting and being done properly are two different things btw. (In response to the box)
