|While pulling the old stereo equipment out of my boat I noticed neither of the vent hose coming of the opening in from of my windshield were connected to the hole in the floor. |
Now that I have installed new amps I am partial cover the hole on the port side and my sub box will partly cover the hole on the starboard side.
What is the propose if the vents? Can I close them off? My only other idea is to reduce the 3" drier hose type line to a 1-1/2" hose and drop that into the hole in the floor. Any ideas?
|thoase vents provide ventalation ( think fume build up) to your bilge and back into yrou engine compartment. Keep them. |
Rememebr this is nto liek a car that has lots of ventalation. In a boat you are in essence putting a motor in a sealed box
|ya you need those vents and they need to be hooked up with 3"|
|You REALLY do need those vents a 1.5" hose has less than 1/4 of the airflow of a 3" hose.|
|Keep them open! |
Those vents are there for a reason, to let your bilge breathe.
It would be similar to blocking off the grill of a car or truck.
|not only is it a good idea - it is the law - two intake and two exhaust vents - coast guard regulations for inboards.|
|Thanks. I'll work on a solution.|
|build a hose into your box and let it flow thru|
|I think I can make it work on the sub side. |
Here is what I am working with on the other side.
I think I'll get the largest 90deg that will fit in the hole and run it up to the vent.
|You can use PVC, or any type, pipe instead of flexible hose.|
