Default world cat cc subwoofer mounting location?

I have a 2001 226sf worldcat and am contemplating location(s) to mount a 10" JL sub that santa brought me, and considering purchasing a 2nd sub. For those unfamiliar with this boat, along the transom are 2 hatches that house (in my current setup) battery switches and banks for each port and stbd motors. These 2 hatches are flanking the corners of the transom. In the center of the transom is a smaller hatch that has the racor filters. To mount the sub in the center hatch, I'd have to relocate the filters as I don't have the necessary depth. I could purchase a 2nd subwoofer and place them in the corner hatches, but then I'd have to relocate the battery switches and primer balls, which seems like a project not worth undertaking.

I am 100% against mounting the sub in the console.

I am exploring the idea of mounting in the gunnel, but haven't yet come up with the best location. Have to take into account rod holders, etc. I've read that bass is not directional, but I'm a fan of symmetry and a single sub in one "corner" of the boat would not accomplish this. Has anyone mounted a pair of subs in gunnels on opposite corners of a center console? So for example, one sub in the starboard gunnel aft of the console, and another one in the port gunnel forward of the console?

I'm wondering pros/cons of this but would think it would provide for the best balance for both driver and passengers forward of the console to get good sounds.

thanks in advance.

If you mount these on in a opposing (symmetrical) layout you may get some cancelation of bass. You are better off in a non symmetrical layout but if you insist on an opposing layout try wiring in an opposite polarity. This will create a push/pull layout which should give you better bass output.

This does not sound right. Are you saying that two drivers out of phase will give you better bass?

Picture a sub on each side of the boat facing each other, as the sound fires forward the two sound waves hit each other canceling each other out. If they are wired out of phase one pushes the sound while the other pulls, and no cancelation.

All sound is basically a wave of moving air (the speaker cone pushing the air). This trick works in home theaters where you have subs in the front and back of the room. Also if you place the subs in the corner you also amplify the output.

What you should also be concerned about is the driver design. Is it designed to be mounted in a certain sized enclosure? If you mount it free air (ni real enclosure size) I may hurt the performance.

I am not that up on auto or marine audio systems but have done a ton of research and actually built a pretty substantial home theater. Just wanted to point out to you that the best placement has more to do than just physical size.

I do agree that I would not want to mount them in the console either, I wouldn't want to subject my boat electronics to the beating they would take from a powerful sub.

i think your best bet would be to mount them on the same side of the boat. As you said low bass is non directional.

I would look for advice from true audio professionals as there is a lot to consider or a least do a lot of research before cutting big holes in your boat.

I have a 1999 266 SF and I have 2 mounted in the Gunnels about where the driver's seat and livewell is located 6"-8" past the side rod holders. I can PM you pics if you want to see my setup. BTW, mine are exactly opposite, but since the seat/livewell is between them, I have no cancelling issues as mentioned above.
