Mojo Sub addition

[russellsmojo]

I have installed many car stereo amps and subwoofers but new to boats. I have heard that under helm is best location for a sub. Any suggestions on the box enclosure, size that fits best there, or pictures to help me?

Thanks

I would remove the fiberglass kick panel.

There is screws holding it down in the cup holder. Then you can unbolt it from the floor and remove it.

I have a Exile Big 15 under mine in a box. Lots of room.

That is a big sub! I will check it out. How many watts are you sending to it?

Honestly not to sure, 2K+ at 1 ohm

I've been thinking about doing the same thing and have the same boat as you so I'll be interested to see what you decide and how it goes.

I was just going to throw my 12 inch kicker sub in an enclosure and throw it in the bow storage area on the starboard side up under the instrument panel.

[jmvotto]

Some have put the sub above the kick panel, a 12 should fit there , otherwise remove the panel and put sub in its place tons of pics in the audio section.

I have the exile 12idvc with 1500 and it has plenty of bass for me.

2013 LSV with fiberglass foot panel cut out to give you an idea. It is a side ported enclosure with a 12" DVC Exile and powered with a Javelin.

The best woofer, is the one executed properly. Having said that, I would first start by opening up that cavity and taking some rough dimensions. Take into account, how much leg room you are willing to give up. This will give you an idea of what the max gross enclosure dimensions can be. Armed with that, you can begin to narrow down enclosure type, as in sealed or ported, and what woofer brand/model, will work best in those scenarios.

Some things to consider, when choosing a woofer. Composite cone over one thats in any way made of cellulose (paper pulp). A tip off are words like "hybrid". They typically indicate a paper based cone with a laminate layer of some kind on the front side. This leaves the back of the woofer open to the elements. Rubber surround. Sealed magnet. A composite or aluminum basket is good. No issue really with a stamped steel, as long as its got a quality power coating over a cheap black paint as you might find on a price point car audio woofer.

once the woofer is chosen, then match it to a solid amp and construct a quality enclosure, done.

I made a custom box with these pioneer 10'. They require only .8 sqft. For a sealed enclosure. They are inexpensive and hit very hard!

I had a sealed enclosure with an Exile 12 in my Mojo. Sounded great and had good output. Mine was located under the helm behind the fiberglass kick panel. Keep in mind I did have the Exile12.1 running it.

My last 2 mojo's I did the WS HT AS-10 under the helm. I did not want to give up my foot rest.

I looked that WetSounds sub up and it is powered and has its own enclosure. How did you mount it up there like that?

[viking]

^^ my guess is he secured it to the kickpanel and built a facade for it

The front is sitting/fastened on the foot rest, back just enough so I could put the carpet panel backup. One back corner is sitting/fastened on an L bracket that I fastened the hull support. This may have been enough support, but I made a leg that went to floor for the other corner. Took the speaker grill off and fastened it to the carpet panel where I cut the hole to align with the speaker. It is a little off center due to the space limitation and taking advantage of the hull support.

Thanks! Being new to Moomba and with my boat being put in storage pretty much right when I got it, I haven't had any time to really poke around the thing to see how it's "put together" I just keep reading and reading....sometimes ending up more confused than yesterday LOL

[ghebert1111]

I'm lucky cause my boat is in the basement so I can head down there when I want/need to. I just went down and pulled the panel off and my 1 cubic foot sub enclosure doesn't seem to fit in the center or right of center but will fit to the left of center. I'll get some pictures tomorrow and post them.

My current sub enclosure is MDF, intended for my jeep but re-purposed, and a real POS but I'll work with that and when everything seems to work/fit I'll build a new one. Now, on other threads I've read to use plywood, is that correct? 3/4 or 1 inch? and I've also read about coating these things with resin, is that needed? Any other tips on building a sub enclosure?

I know the feeling CFD3Captain. I will not pick mine up until spring (that is if I can make it that long).

I'm no expert by any means but Marine grade baltic birch is a good choice. Yes Resin is a good way to seal it and resin the inside on a ported enclosure as well. Most important is precision cuts so that you don't have any gaps.

[jstenger]

I used regular 3/4" Birch, and sealed all the seams with Liquid Nails. I then painted the whole box inside and out with a few good cotes of oil based paint. Finished the front with felt, sprayed with a clearcote, to match the factory carpet.

How did you attach the leg? I've got my sub enclosure resting on the edge of the kick panel and I have a metal strap running from the back of the box to part of the boat for support but I still want some leg support. I have a crazy idea using some hinges but that might be a little to much MacGyver.

I have a Mondo, but I could fit 4 10s under there.

Brett, what's the box situation behind the 4 subs? All in one box? Independent boxes? Sizes?

I believe they are each in their own chamber. Can't remember exactly the size but it's pretty big. I didn't loose any foot room & being low wattage subs they hit extremely hard and are very clean.

Has anyone used azack sheets for building the box? I fear water will get to the wood even with all the clear coat and paints, unless you fiber glass it it is susceptible to water. This azack is 3/4 thick and very rigid, and all composite.

The issue with those materials, if finding a glue/caulk/sealer that will stick to it, making air tight seams. Its all about how the wood enclosure is constructed and installed.
