Hey guys, I may be wrong, but the other day I went fishing and put the fishing rods in the trunk. I opened up the center piece in the back seat to stick the poles through (from the trunk into the car). And while driving to our fishing spot, I noticed the bass seemed to be much louder than before!!!!!! Of course, I would not want to drive around with the center piece open all of the time, but I am pretty sure it seemed much louder. In any event, give it a try and tell me what you think!!!
