Hey everybody! I was just is there a diferrence in power handling between a vented enclosure and a sealed enclosure. I just purchased a DC Audio Level 3 15 with the Level 4 coil option, dual 1 ohm. I'm running a Hifonics HFI 1500d @ 2 ohms 1000rms. I was going to use a 2.25^3 ft. enclosure in a Nissan Altima or could I get away with running that much power in a vented enclosure on the sub? Any input would be greatly appreciated.

Yes, there is a large difference in mechanical power handling when using a vented enclosure; but as your enclosure is only 2.25 cubic feet you should not run a risk of mechanically damaging your speaker. Thermal power handling is another story, but that is entirely up to you and how hard you are on it.

I'm sorry the 2.25^3 ft enclosure is sealed. I ordered the upgraded coil to run more power than the 600 rms thats recommended. So would the Level 3 with the Level 4 coil be ok on 1000 watts rms in a sealed enclosure?

Isn't 2.25 cubic feet a little small for a 15 ported? Won't that sound like ass?

Edit: nevermind you meant sealed

2 cubic feet is recommended for them, low end and efficiency will increase with the larger enclosure, just remember, you have a gain on your amp for a reason, use it correctly and you won't have any problems.
