View Full Version : Subwoofer in 93 Prostar?

03-04-2011, 12:36 AM
Hey guys, I'm looking to put a subwoofer in my prostar 205. I like bass.. Where would be the best place to put one? I was thinking under the dash by the feet? or under the passenger compartment or even in the front under the storage? what would be the best place and the best noise?

I'd say pull out the kickboard and put a box between it and the bow storage (can't remember how much room is up there). Have the front of the box look like a new kickboard. Under the observer seat is pretty cramped in that era of 205. Of course, since you can't get a ski under there, it might not be a bad place for a sub if you vented that area in the wall of the walk through.

I have the 94 205 and I am putting my sub in a down firing box in the storage behind the observer seat. I am doing it there based on my brothers professionally installed stereo setup has the sub in the same place in his 04 206 CC. You can feel it....

I can't remember, is that area vented to the port side of the observer seat? That sub is going to sound a lot better if there is some way for the sound to resonate into the cabin from that closed compartment, even if the sub is down firing.

this is what i did, color match of carpet looks more off because of flash than it looks in person.. its close but not perfect. sounds great, will vibrate the whole boat.

how did you take the kick panel off? and what kind of subwoofer and amp are you running?

In a 93-95 205, there two or three stainless screws.

how's the sound? and how far did the box go in? total depth of box. Also, how is the leg room?

The available depth in a 93 is going to be a bit less than in that 96 or newer 205. The bow compartment is not connected on the 93 IIRC.

The quality of the enclosure is everything when it comes to sound (BASS). Be sure your box has the right amount of air space. It looks like the box in the picture above is small, but it could be the angle. Remember too much power is always better. The install looks great though. Just don't kick it.

Under the driver's helm with a direct-radiating subwoofer is definitely the way to go if you have a boat with the space. Its much better than trying to vent out of a locker or compartment which always creates losses.
Start by determining the amount of depth and space you are willing to sacrifice relating to the foot/legroom. Once you've established the maximum enclosure displacement, decide which size of woofer is optimum for that particular displacement. Two 8"s might consume the same space and collectively have similar surface area to a single 10" for example, but may offer an enclosure shape that is a better fit. A 10" bass-reflex may have more ouput than a sealed 12" for example in the same size enclosure. Again, the boat will usually dictate the maximum enclosure and the enclosure will dictate the optimum woofer selection.
A woofer and its enclosure form a tuned circuit of sorts. The right match is key. Forcing a large woofer in a box that is undersized produces poor sound quality. Certainly the inverse produces poor quality also. Most good woofers offer detailed parameters for enclosure selection and usually provide optimum recommendations.
You would be surprised as to how many people choose the woofer first and then figure out a way to fit it in.

Sounds like a great project. Right now I'm replacing all the speakers and amping them and getting tower speakers and a new head unit. Also installing two batteries.

On the 94 205, there is an alumimun brace behind the kick panel. (Both sides.) The brace would prohibit a tuned box of any size or depth, on the drivers side, if you want to actually want to drive the boat. I recommend taking measurements, before buying a large speaker, if your intent is to install on drivers side.
