I'm using 2 10' Kicker Free Airs under my bench and they are great. I'm rumming a Kicker 400w 2 channel amp. Hope this helps.

I got 2 of the newest Alpine marine free airs under my rear seat. Got the mono channel pdx amp, rated at 600w, actual test was about 680w. They pound.... with the seat off, not as hard, but put the seat on the the entire boat shakes. can hear and feel them even at WOT. Not to mention the ladies LOVE them.

JL AUDIO 10's are the BEST you can get. I had 4 under the back seat free air and sounded great!!!! you will not be disappointed.

JL is the best have 2 in my boat.

jl audio is the best subs out w3 or w7

Take it from someone that was in this business for 15 years. Free air sub will never compare to sub in a sealed or ported box. JL Audio is the best bang for the buck.

I have a 12" Alumapro in a ported box powered by a JL Audio 500/1 amp and that thing pounds. Ported boxes in a open boat are key.

I agree JL's are the best. I've been doing stereo stuff in my own cars for 15+ years also. But I have never done a free air application or a boat.

I have all JL stuff in my cars, but to say that the marine JL stuff is a better bang for the buck than the new marine Alpine stuff, just isnt correct. They handle the same power, but cost twice as much. I'm not looking for competion quality sound on the boat.... hell with the dry exhaust at speed, you cant hardly hear the tunes anyway!!!

I agree, the free airs will not compare to a sealed box, but The free airs in my boat are not going take any space. They are going into a hollow unused area.

As far as bang for the buck. I'm pretty sure the 2 Alpine 10's are gonna sound better than 1 JL 10 would. The cost for 2 Alpines and 1 JL is the same. Alpines are rated at 300watts rms/900peak. JL's rated at 150watts rms/300peak.

I have JL 10" (2) under rear seat of top gun....not good sound without box.....
