Ive got a 13w7 in a Prowedge JL box being pushed by a Xtant x1001.....Its installed in a Dodge Ram ext cab CTD and with the windows UP its not that impressive(SQ is very good though)Roll the windows DOWN and it gets alot louder but still not quite up to my expectations of what a $1k sub should sound like.
Im going to strap another x1001 I have on it to see if that helps any.If that doesnt work,then ill get a ported box.
Maybe im just expecting to much from what is supposed to be 1 of the best subs on the market???
