Yeah I was thinking free airs myself, cool. Hmmmm what to do if it rains?

Free air woofers
 

The reason your JL's did not work is that they have a low "Q" and were designed to work in small sealed boxes. Kicker and other companies have woofers designed to run "free air" and have a high "Q". One item you will notice is that free air drivers have a very stiff suspension and it takes alot of power to drive them. Try moving the cone before you install it and as hard as you have to work to move that cone so does your amplifier. You can and will get more acurate response with woofers in a box than a free air design. FYI...When installing in a free air design- adding items like dock line, fenders, etc will change the sound characteristics when placed inside the seat box.

Sounds like Baja 2700 really knows what he's doing. It's not hard to build boxes. Most speakers come with instructions on how to make them. If you do not want to build them then find flat front boxes and bolt them in.

You'll be infinitely more happy.

FYI I mounted my Subs in the FRONT of my boat and used the dead area in the bow for boxes. Works great unless your trying to take a nap.

sound
 

After 25 years of designing 12 volt amplifiers you learn a few things about sound. I like your idea of running the woofers up front since they are less likely to be sun or water damaged. At these low frequencies sound is not directional and you are less likely to experience null points. (areas that you walk into and there is very little bass) Let me know if you have any questions and I'll try to answer them.

When too much is not enough, more is better and excessive is just right!

I have a stupid question to you guys with these huge a$$ boat stereos. Are these stereos loud enough to play and actually hear while your running the boat or do you only use them while anchored? I only have the stock clarion radio/cd player in my boat and have only used it 2 or 3 times. No way it could ever be heard while running.

I have about 1,000 watts. I gave up on trying to listen while running a while ago. Better to hear the engines and what they're doing.

All I hear is wind and superchargers.:D :D :D

can you hear it
 

I did 4 10 inch woofers each with 500 watts on them, and 4 6.5 inch coaxials in the interior and at 70+ mph I can hear it but I prefer the sound of the 502. In fact when I built the motor I threw the captains call in a box!

Re: can you hear it
 

What coaxials did you use?

I can hear every beat with mine. No matter what the speed. But you had better be ready to hit the volume when you get to the no wake zone.

Re: can you hear it
 

I agree with 2700.

Even if I could play music loud enough to hear when running, I wouldn't do it. When running, I want to hear the engines in order to detect any little hickup with them.
