I'm thinking about doing a bit of work on the boat stereo. The boat is a 30 foot cabin cruiser so it requires ALOT of sound. Currently I'm running an Alpine PDX 4.150 on a pair of Clarion marine coaxials and a pair of infinity reference coaxials. I'm running an Alpine PDX1000 on two JL Audio 10w3v2's in a sealed box. I'm considering changing those subs out for two Diamond Audio D910D4's. Is this worth the time and money? I'm looking for unreasonable spl levels and reasonable sq. The JL's sound ok in the but I have a neighbor at the mooring with the same amp and a pair of Kicker CVR's that were outshining us last weekend. I simply can't have that
I also thought about changing out my coaxials for separates as I have both a set of Morel Docap Ovations at the house and a set of AVI Direct EL's. My concern with that is that the level on the boat stereo is not always under my direct supervision and I'd be upset if someone cooked those drivers.

Give me your thoughts.

is it possible to show where your equpiment is on the boat? Like could you draw an overhead veiw and show where everything is? Sometimes positioning is key.

also, a ported enclosure might be able to help you get a bit louder

Ya, what he said. And without the cost of buying new equipment. Wood is cheap. lol

Hmmmnn I don't really have the computer skills for that. I have the two tens on the deck in the bottom of the L-shaped lounge in a sealed 2 spare foot cabinet. In a separate cabinet on the deck I have the two infinity's firing toward the back of the boat and the clarion marine is firing forward. I have the other clarion marine in behind the driver. As you can tell imaging is certainly not a top priority.

The couple of cabinets I've run ported on the water have chewed the subs up really quickly. The salt air seems to have its way with the woofers in very short order when it can get at the back side of them.

Being on the salt water as well, I have yet to have the same issue as you do. Salt air is salt air and if it attacks the backside of the sub, it is going to attack the front. If you want loud, we use Digital Designs in boats almost exclusively in ported enclosures. We use either Morel or the Eclipse marine speakers (waterproof not water resistant) and have great results from them. There is no doubt that the Morel are going to step you up a notch in the performance category and handle the power you have now, the trick will be to set the amp right and ensure that the system is used correctly.

I had a look at the Morel site and I can't find their marine speakers. Do you have more info? As far as the Digital Designs subwoofers, will they have more output than the 10w3v2's that I'm currently running in a sealed enclosure as well?

Morel will not make a marine speaker but they are one of the few speakers I would short list that would handle the power you have ready with that alpine amp.... Waterproof speakers, Eclipse. Water resistant speakers, insert brand name here, white grill, stainless screws and away you go. The DD subs in a proper ported box will have substantially more output than the JL. When you rebuild the boxes, it is a darn good idea to both resin the box inside and out and go so far as to take them to a spray in bedliner place and have them spray the inside and outside of the boxes.

Being on the water, especially the salt chuck is far different than most installers are aware. It is truly a different set of rules that comes into play. does stuff last like it does in the car, definitely not. Cerwin Vega also has a line of speakers that may interest you and has a waterproof sub as well. One of my reps just sent me a video of it being thrown into a pool for a 1/2 hour while playing, coming out and still going like the energizer bunny.
