I have an open bow Sanger. I installed a 10 woofer in the storage area under the passenger seat. When I lift the seat slightly the bass gets much louder because the woofer can get more air. My question is has anyone ever ported the seat to allow more air for the speaker to breathe? If so where did you drill the holes and how many and how big in diamater?
I was thinking of drilling some 4" holes in the carpeted area under where the seat sits to in essence, port the observer seat storage and allow for more bass to make its way out of that area. I haven't decided on whether or not to do this yet, so in the mean time I just added another sub in the driver's footwell area.
I had the same problem as you. You could hear more bass if you opend the passenger side seet. I added ports to help bass escape. Now you cant hear a differance if the seet is open or closed. When you cut holes large enough to make a differance the pannel or seet gets pretty week and needs some support. Making a grill can add the support im talking about.
That is a old pic of the orignal grill I made. I have since made a new one thats made of MDF (wood) and then coverd with epoxy resin and then painted. The grill is bolted to the passenger seet threw the seat itself
cool thanks, I have a Sanger and the seat itself lifts up leaving the part that you cut out on your boat. The material is fiberglass so I am wondering if I cut 2 or 3 3 inch holes if it would be enought for the woofer to breathe. Did you experiment cutting less material out or did you just cut as much as you could to get the most air out? thanks again for your help. Anyone else out there do anything simular?
do you move the batteries if you put the woofer under the drivers side? I have two batteries and my amps under there now. I will see if I have room. If not, I will try the cup holders if I can get the stock ones out with out damaging anything.
