I searched this forum and found several people making references to replacing their blown factory sub with a Kicker (652 I think) for a drop in replacement. I haven't been able to find anything, except a 1 ohm driver, but believe the factory driver is 4 ohm. Can someone verify the impedance and max depth?

I'm trying to avoid a separate box and amp, so hopefully there are still some good options out there.

Thanks
