Loudest 300 wRMS sub?

[ntense702 10+ year member]

what kind of subs and amp do you currently have and what kind of box do plan on putting the subs in?

edit-didn't see previous post

well i have 2 infinity 1230w's and there just not loud enough, but i am only giving them 250 wrms each with my profile amp, maybe ill just get like an 700 wrms amp? think that would make it alot louder?

If you have them in a sealed box right now, go ported. If you are underpowering them then get a bigger amp. Although they are 300w RMS and you are giving them 250w, so the extra 50w will not be that big of an upgrade. However it IS a profile amp, which might be over rated.. So a beefier, better quality, amp might be in order.

im looking at the kenwood kac-x811d for $200 shipped off ebay, its a really nice amp... isnt it???

look if you are serious about going louder I'd suggest looking into a whole new setup, the only experience I've had that fits your situation was when I had 2 coustic 12" svc 4 ohm subs off a single coustic 400D amp, the subs were only getting like 200 rms a piece and it banged nicely and sounded good as well, (d@mn I miss that setup) I highly reccomend you look into coustic's stuff, their prices are reasonable and they get very loud off little amounts of power, that is the advice I'd give you if you consider changing subs, if your infinitis are not loud enough, adding another is not going to make much of a difference, check out coustic.com

That amp will work pretty good.

If you want a 1ohm load wire 4 infinitys in parralell, if you want a 1.3ohm load wire 3 infinitys in parralel.

I would go with three infinitys in a ported box off that amp, if that doesn't wail, your deaf and there is nothing we can do to help you.

I have to agree there, and for the record I put the exact same infinity sub in my moms ride in a 1.5 cf sealed box powered by an alpine 250 watt amp, and the amp beats the p!ss out of the sub and it really doesn't get all that loud, my suggestion on the coustic subs was based on 300 rms subs that get loud, and my opinion is they are the loudest subs off that amount of power I ever heard, you should look into them if you want to remain with a setup pushing little power, that's all I have to say

not to help just to argue the atlas 12's slam at 220wrms a piece ported at 34hz!

crazy loud for that kinda rms power!

I think if he did get a DVC 4 ohm sub, it would be 1 ohm to the amp. The problem is that two of the subs will be at 4 ohms, and the third will be at 2 ohms. So it would be getting about twice the power that the other two subs are getting, and I guess that would be a big problem, although I don't know what the effects are.

of course you dont . . . .(because what you said has no effect either). when wired together they all produce the load on the ampat the same time not seperately.

If he got one DVC 4 ohm sub, he would be mixing sub models/ brands, which as mentioned, will get sloppy. If he were to do that, however, he would need a sub that could handle twice as much as the other 2 subs, since it would be like wiring up 4 SVC 4 ohm subs, just one sub will be getting 1/2 of the entire amp output. Should he do that? No.
