Big ones. You'd likely save money and get better results using an electronic low pass crossover. HERE's the passive crossover link. ------------- Support the12volt.com

The only reason you would want to use a coil on your woofer, is if you have a single amp to power your entire system. If you have a dedicated amp for the subwoofer, as stated earlier, an electronic crossover, be it integrated in your radio or amp, or stand alone, will give you much better results.
