1999 Pro Air Stereo and Speaker install

[rlabelle7]

Just bought new boat 1999 pro air, loving it. I am installing a new deck and speackers and wanted to see if anyone had some tips for me.

I think the stock speakers are 5 and 1/4. I want to put new through out the boat. is this the right size stock. Any tips on the install would be helpfull!

ALso i purchased a new ALpine deck similar to the old stock but new. Will the old stock wire horness fit into the new alpine Deck or will re-wioring be neccessary.

Thanks ALL

Speaker size should be correct
You are going to have to re-wire at the head unit

I have a 1999 Super Sport and I am pretty sure your setup is the same. I believe your speakers are mounted behind a vinyl pad. At least that is the way I remember my friends Pro Air. You can go to 6.5's if you like. They are firing down a 5.25 PVC tube but you will get a little more out of 6.5's. That is what I have in my boat.

The other option would be to surface mount and go to 6.5's. You will get more sound and an updated look. There are threads here where others have done just that. Do a search. I know Earmark Car Audio, this forum's sponsor, has done it multiple times for people. They may have some finished product picks.

Thanks, I think i will go with 6/ 1/2 with the surface mount. I will do a search and see what others have done.

I did this a short time ago. I have a post on here somewhere about how I did it. Here is a pic of where I added the 4th speaker to right behind the driver's seat. I had to cut a new hole in the starboard and the hull to do it, but I had no room on the driver's kick panel since I have 2x12" subs there. Sounds great to me.

Something to consider for those who have coaxial speakers mounted towards the edge of an open coaming bolster:

In many of these applications, you can reach behind the open bolster from underneath and touch the speaker without obstruction. When the speaker is mounted just inches from the open perimeter, the speaker is undamped. This means the simultaneous compression on one side meets the vacuum from the opposite side and cancel out any radiation below a certain frequency or wavelength. This cancellation effect also serves to eliminate any air resistance that would damp the cone and restrict uncontrolled excursions. The net result is diminished midbass contributon and a serious reduction in power handling.

The solution is to encapsulate the backside of the speaker with an injection molded isolation chamber. The small cup will raise the speaker/chamber collective resonance so you won't gain much of the lost midbass. However, you'll see an increase in overall output and a dramatic improvement in power handling.

I recommend this whether your coaxials are running fullrange or highpass (used with a sub).

In advance,

If your mounting already provides sufficient front to rear isolation then this chamber serves no purpose. All inboat or automotive coaxials are ininite baffle so a large volume of air behind the speaker is preferred... As long as you have isolation.
