The amp. It is much cleaner than it looks in this photo. This is mounted underneath the passenger's side of the front end enclosure between two support fiber stringers for the top of the front of the boat. You can also see a portion of the sub box which runs up the driver's side of the storage area.
This is another pic of the sub enclosure.
And another pic of the sub enclosure. I only put a grill on the sub facing the passenger side as this comes in contact with the storage area. The other sub is essentially protected by the driver's foot rest.
One final pic of the driver's speaker enclosure.
