soundstream t4 12 900w rms TRUE WATTS! has some wear theres a hole that was sealed and it looks like sh** but that doesnt matter because it still SLAMS! i had a 2500watt power acoustic amp on it and it would put it in protect mode on only half gain so it needs a BIG amp to put it to its full potential. its missing two screw on terminal peices on the one side as its duel voice coil. has some scratches but overall its a nice price for a competition grade sub. i dont have the room or the equipment to put it in my car so im selling it.
