Default Speakers in t-top box.

I'm looking to install a c e smith t top box in my boat. Inside it I will flush mount my VHF and stereo head unit. I have thought about installing 2 downward facing speakers in the box. Has anyone done this with good results? Is there a free air speaker issue? Or will the flush mount board I put in take care of that. I don't have much in the budget left for this, but it seemed like a potentially cheap project.

If it matters, I have a hydra sports 212cc and will be installing a fusion ms-ip700 with fusion 7" speakers.

I have seen t top boxes with speaker mounts in them, but I have a great deal on a c.e.smith box right now and I imagine the others will cost more.

It will work - it's not the best solution as you lose bass, it takes power, makes the floor of the box uneven and is a wiring hassle if you head unit is below. Without a backing, people throwing things in the box can damage the backsides of the speakers....keys, phones, etc., It is the last option a professional installer will use.

best solution for speakers in any CC is low and inside the boat...

That is exactly how I have mine. Two Sony 6" round. The box is divided off so nothing can come in contact with the speakers to damage them. It has been a year now since the install and so far so good.

I've been thinking about doing this myself. I have 6.5 Fusions mounted on the sides of my boat just below the rail facing my center console. It's plenty loud while we're in the boat but not loud enough to rock the sand bar scene. I'm upgrading to JL audio 7.7's soon and I hope this will bump up my volume. Most boats that I've seen that can really "rock" have speakers mounted under the e box or under the t-top in some fashion. ??? I don't want to put the speakers up there but I think that would direct the music better for the sand bar scene.

If you are looking for sandbar speakers there is a much louder and easier way, and we did it a lot when I was installing. Get set of good box speakers like polyplanar MA7500's and put some 3M Dual Lock pads on the front or side of your boat, or just set them somewhere on the gunnel, t top etc... Run the wires from your amp to quick disconnects at the front or side of the boat and set em up. Point them where you want...here's some I found in the garage from my old boat.

I will have a first set of speakers mounted low on the console. The head unit is 4 channel and will be mounted in the e box so it seemed like it would be easy to add a second pair. The stereo and VHF will be flush mounted on a panel that will close up the front of the ebox. There will be no way for people or objects to interfere with the back of the speaker. I thought this might give a more sealed effect for the speakers not to lose too much bass. I figured someone might have done this already, and I wondered what to expect.

a far better listening experience for the captain and boat is transom mount the other set firing forward or opposite each other. It is amazing how much more depth the music has...

This will work fine for what you are trying to accomplish. These will actually be the loudest speakers in the boat for the captain since they will basically be right above your head. The bass may not be as good as the speakers mounted lower but the highs will be much better so it will balance itself out. Enjoy

While i agree, mounting speakers and running wire to all locations on my boat is not easy. I thought one pair low on the console, or possibly in the gunwhales, with a second in the box might not be a bad setup all things considered. I let you know what I decide one and post pics when its all done.

I have a DC Whaler little different setup than a CC but the gunnel mounted speakers have worked well for me over the last ten years. Changed my stereo system this year when I added my Simrad NSS8. Went with a Fusion SonicHub and in addition to the gunnel speakers I added a sub and Fusion zone amp to run it. Had to use my imagination when it came time to install the sub. Ended up putting it the helm console shelter and building a sub box under my starboard forward bow seat. The sub install doesn't impact on the dry storage area.

Gunnel mounted speakers .....





Sub Install ...... my problem was I really didn't have any large surface areas in the cockpit so I looked for other options. This was the best. The sound quality ended up being really good.

Before sub install ......




After sub install .......



Zone Amp ......



Fusion wired remote ..... did this so my first and only mate could control the SonicHub without having to use the NSS8.

Is this close to what you have in mind? If so, I have enjoyed this setup. The one draw back with my setup is while you are running, you can't hear the sound that well. It really does well for blasting tunes to the beach though.

I had a pair of JL 7.7's in my upper helm box firing down. The sound gets blown away when you are underway. If you want to hear the sound while you are out of the boat it is not a bad option but 7.7's sound a hell of a lot better low in the gunnels or read deck firing forward. I have put a new helm box in the tower and scrapped the speakers firing down. Not the best location for me at all.

not really. this wont be my main or only pair of speakers, more like a bonus due to low cost and ease of install. basically, i planned on having just one pair of speakers mounted in the gunwales, facing in, for optimal sound. problem is running speaker wire out to the gunwales is a bitch of a job. i re-measured and it looks like i can fit speakers mounted in the console facing out. (the console door eats up most of the space on the port side, but a speaker will fit.) i figured this would be easier to install. In my attempt to have everything flush mounted and clean, (no spindles and exposed wires) i found a deal on an electronics box, and will mount the vhf and stereo head unit up there. i figured it'd be easy to drill two holes and have downward firing speakers that'd be easier to hear than the outward facing speakers in the console. super easy to install, and the only added cost is the pair of speakers. I'd probably prefer one of those ssi electronics boxes that have the speaker mounts pre-molded and facing right at the driver, but I won't be able to find one for $250. i'm pretty much and the end of my budget, and will be paying a guy i know to install or help me install everything. right now, for everything; raymarine e7d, through hull xducer, speakers, vhf, and stereo, I have the install fee budgeted at around $750. i feel like i might be stretching that with the e-box and multiple speakers, i'd prefer to learn to do this myself, but i don't have the tools, knowledge, or time.
