I will look into it and see which sub is designed for free air use.......next problem! LOL, JL make a Marine amp 900/5 channel, but, dont make a 1000/1, just a regular automotive style, I would kinda like everything to "match", so, was thinking maybe I could use a pair of 750/1's which are marine style to drive the 4 subs at the back?, I think using just one 750/1 wouldn't be enough to drive the 4 subs, 2 of them would be too much though, so, I would have to back them down a bit.
If you really want 4 subs, I'd get 2 500/1's for each pair. Another buddy had that setup and it made your eyeballs bounce!!! I'm real cautious about where the amps are mounted and not overly concerned about using "marine" amps when I'm installing them in the cabin....marine speakers however are much more necessary.
I think rather than run two 500/1's I will just run one 1000/1instead, now you mention it, the amps I have now are mounted in the cabin and they are just regular automotive amps, not "marine" ones.
I dont think JL makes an 8" marine subwoofer though?, just 10" and up, they do however, make a 8" automotive sub.
I am thinking of using 4 of these, what do you think?
I would go with Boston Acoustic Pro 5, 10" subs. They will sound as good as the 8w7, but go deeper and use a smaller box. And you don't have to worry about where to put the port since it's a closed cab.

Both mine & James only used 1 500/1 amp on 4 subs. The 10" subs are rated at 125W which 500W loads them perfect. It is not a marine amp but none of us have had any problems since it is not in the cabin. It is a great combo. I just bough2 of the new 4 channel marine amps (75W) to run the 4 pair of 7.7's. I do not like to 6 channel amp, overheats easy. I had 2 sets of speakers running on 2 ohms. I dont advise that at all. On hot summer days, they cut out first every time. Going 4 ohms all the way this winter.

Those are not marine subs so I wouldn't use them.......Linster posted below and is opne of the guys systems I have mentioned. The way that system sounds I was certain he had (2) 500/1 but he just stated there is only one. I think he also has (3) sets of 7.7's but not sure......the boat rocks though!!!!
Don't make the amps push too many speakers and keep in mind what he said, if you push the equipment hard it will overheat in the summer and shut down.......and usually only when you've got 20 people bouncing to your music!!!
W7's cannot be mounted free air. If you do not intend to build enclosures, stick with the 10" marine subs. Just a thought, you could build a ported enclosure for 1 10W7 in the cabin and run the free air 10's in the cockpit.
Thanks Guys!, thats great info, I am VERY glad I found out I cant use those subs BEFORE I bought them [they are pricey] I can still use 1-10" in a box in the cabin, but, will probably use marine "free air" subs in the cockpit, who would you guys recommend for a good marine 8" sub?, like I mentioned, I would have loved to squeeze four 10" subs back there, but, there just isn't enough room.
I have been looking at the 8" Polk Audio subs, they use 2 voice coils and are Marine certified, any thoughts??
Thanks again guys, I have learned more in the last 2 days than I have in the last 10 years!

Depends on what sould you are trying to get. The JL's are the best all around in my opinion, they are very good for clear bass thumping music. They also do well for rock. I had a friend who used JL 10" Subs for Bass, and MB Quart for speakers. Sounded real good also. It was not as bass but more of a very clear high sound. If you never play thump music, this is clearer for rock.
Bottom line is you can go a lot of ways. the key is to match the amps to the speakers correctly. You dont want a speaker rated at 125w and only drive it at 75 or 200. Pick the amps to the speakers. JL does a good job of that There amps are designed for there speakers, not everybodys speakers. Good luck
