well i have the infinity baselink II in my sedan for now, i had it mounted flat but moved it to be upright for more space. It sounds pretty dang good for the size of the unit, has enough power to rattle ur car if you dont have dynamat. Although there is no comparison to my little bro's 2 12" Fosgates. Also i found that a cheaper head unit does not cooperate well with the amp/sub without proper sub levels on the hu itself but after i got my Alpine IVA-W205 HU it sounds ALOT better. As for the amp card for blII i used it for awhile but the speakers sounded better through the alpine unit itself so i pulled it out. Overall i would highly reccomend the baselink to anyone that needs the extra space but wants to have good sound.
