Hello, I'm looking for recommendations for a drop-in sub replacement.

Currently running Polk dB651s in the doors and a Sony GTX-700HD head unit tied into the stock amp and sub.

Already impressed with the improvement over the stock setup, but considering replacing the factory sub driver with an aftermarket unit.

What is the impedance of the current DVC sub? Can the DVC be replaced with a SVC?

Any feedback would be appreciated.

This is a subject that has been discussed in great detail. If you'll use the search function, you should be able to find some of the discussions.

On a personal note, I think a drop in replacement running off the factory amp is not really much of an improvement. I would first add an aftermarket amp to the factory sub, and if that is not sufficient, add an aftermarket sub as well (Elemental Designs would be my suggestion.)
