I have a Precision Power 12" IDMAX. This is a top of the line sub comparable to a JL W7. Its a dual 4ohm voice coil. It was in my Talon for a couple years, so it didn't get used too much, as I have hardly driven the car the last couple years. $200 I also have a custom fiberglass 1.25 cubic foot box that is made to fit in the spare tire well of a 2G AWD DSM.
I also have a Rockford Fosgate 12" HE2. It is a dual voice coil 4ohm sub. Its in new condition. It was only used for a couple months in my EVO before i sold it. $75
I have the amp I used to power the IDMAX. Its a ESX Q475. At 2ohm's it puts out around 1000watts. These were a pretty popular amp a couple years back due to thei clean high power for a decent price. $150
