I need suggestions for two ten's on 900watts at 2ohm final that will work in 2.5 cu vented in a boat.

 

not sure for power wize for subs but clarion, alpine has some marine stuff or look for subs that are not made out of paper and that the surround is rubber or something ( not foam ) might have more luck that way

 

I know the kicker series (CVR anyways) are marine suitable.
2 12inch CVR's are 400w RMS each, so that amp should be perfect when paired with 2x 2ohms DVC.

 

if the kickers are alright with water, they might be decent choise. Or something cheap like Bazooka depending on what you after

 

how big is the boat and more info

 

MY friend has 2 rockford power 8" subs that handle 400rms each and trust me they blow away most 10" subs I have heard if u are intrested in a price pm me back!

 

I noticed you said 2 10's, not 12's. Kicker also has a 10in model rated for 400w RMS (which is what I have, and I love iT)

 

I'm running two older JL 10W0-8's wired in parallel on my Sunrunner Ultra 302 built into the topside seat bottoms (sealed box) with an Alpine PDX 1.600 and they pound very nicely. I've had them in a salt water environment now for 5 years and they show no signs of giving up. Trust me they get very little relief as well. I've installed two 12" JL's in my friends Bayliner as well and he's been very pleased. I've used Kicker 10's as well in a boat without issue. I've actually had more trouble with purpose built "marine speakers" than anything else. Hope that helps.

 

Go with whatever you like and put them in a bandpass box!! :P

 

Thanks for all the advice guys. I'll get back to you with what I've chosen.
