they are the exact same sub mechanically. the only diference is cosmetic, one has a black basket one has a grey basket. they also have different dustcaps. i dont have any pics right now as they are installed in my car, lol. they are D6 coils, and i have them wired to "1.5" ohms. they meter out at just below that including the sub wire.
I have some incriminator audio death row 15s, 1000rms each (underrated) aluminum 3in coils ill let go for 500+shipping, they are a sql sub sound **** good and get loud
