They are made in both SVC and DVC format, just because yours are SVC doesn't mean his are Pretty sure they no longer sell the single, just dual now. If its DVC and 4ohm then my ex gf is interested lol
If its dual voice coil it will have 4 terminals on the side (1 positive, 1 negative for each coil). If single, it will only have the 2. :thumbsup: for the sale though.
