Says you have an Orion 2500d in your sig, so I just assumed.
Do what you want. I mean it will get loud with either setup, but you wont be into the 150's with it. You have to double the power to gain at least 3dbs after so high into dbs. Least that is what I have read numerous times on here. If you have the room, do the Kickers and call it a day. Seems that you have already made your mind up, which seems like you have made the choice before you made the thread, which I dont understand. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
Good luck with what ever you decide though.
