[QUOTE="OhmLoad, post: 8698144, member: 679086"] Sweet, you've done some research. 80prs. One of the best sounding Pioneer decks ever produced. You will notice that over time the face plate gets a little loose from vibrations. So as for your one 12" subwoofer having dual (two) 2ohm voice coils connected to a mono amp (this is very common by the way) will produce a 1ohm load on your amp when wired parallel. The guys installing it will know exactly what this means.
