do you need a s-converter to bump the lfe voltage up??

It appears your original queation was never answered. No sense buying anything until you know you need it. Just my opinion.

 

[Mike P.]

Try the TX-607 with whatever amp you're getting first. No sense spending more money than what you have to.

 

[Mike P.]

Kevin, depending on what you are up to you may also need a Hi-Pass filter. What sub are you building?

 

[Mike P.]

The EP amp has a HPF at 30 hz. Are you building a sealed music sub?

 

[Mike P.]

What are the parameters of the Kickers and what are your plans for the Fi Q that you're getting?

 

[Mike P.]

First things first. I found the parameters for the CVR12 DVC 4 ohm subs. Do you have them wired separately for a 2 ohm load or a 8 ohm load?

 

[Mike P.]

i think 2 separate?

Are the Kickers wired separately or are they wired together?

 

[Mike P.]

For music a Q of .7 is considered best. The sub will take 350 watts if the 30 hz HPF is used on the amp.

 

[Mike P.]

i was wondering about running 550 to them on 8 omhs non bridged

For a music sub as shown in the model above they'll never take 550 watts. They'll bottom out long before that.

 

[Mike P.]

Well this is not only for music its for a HT sub as well

You previously said the Kickers were for music and you were getting a Fi Q for HT. I'm lost.

 

[Mike P.]

Here you go. 2 Kickers and 1 Fi Q18 D2. Both need a Hi-Pass filter at 18 hz. You'll need a port 8" diameter and 20" long. Not sure how the box can be "easily modified" to switch subs but I'm sure you'll figure it out.

 

[Mike P.]

Cool, great this is diagram show it from the Fi q sub in the box and then if the kicker were in ther with just them selves right?

Yup. The link isn't working for me. You can design your own cabinet so it has a net volume of 16 cu.ft.

That's only 6 cu.ft. not 16 cu.ft. Use the calculator link I posted to see how big the box you need is.
