Ya I dont think you can go wrong with the VR. Its a good all around sub, and a decent price.

Well in the end I guess I might just as well stick with the Comp VR. It will be what it will be.
It's just to supplement the Monsoon (top of the line factory) in the wife’s car so she wont be pounding anyway.
Thanks Amigos!

Well see heres an issue with pre fabed ported enclosures.

As smoker pointed out, the tuning frequency will depend on the subs displacement, to an extent.

It may be tuned to 38 Hz now, but when you drop in, say a W7 it may goto 42Hz.

Maybe you put in an RE series sub... Maybe 38 Hz...

It wont change to much, but it will...

Hi Ryan and Smoker.

The info on the port is as follows:

"Pre-Cut Slot Port Hole: The box comes configured as a ported enclosure with a tuning frequency of 38Hz, with a pre-cut, 1-1/2" x 11-3/8" slot port with a hard plastic port flange. If the driver manufacturer suggests using a sealed enclosure, or that a sealed enclosure is preferred, you can replace the port flange with a slot port plug, using the same 4 screws from the port flange. Note: There are no provisions for port trimming with the slot port."

Tha Assassin sub is a single 4-ohm. I am looking to run 2-ohms and one sub. Nice price tho!

isnt the tuning of the box going to rely heavily on which driver goes into the box?

i would either seal it or measure the port and see which subs work with the box size and port....

That might work also...

I see you got a tad more power (should be ok) and the box is tuned higher...

Box: Q-Logic QLH-1.7512SS (12" 1.75cf Ported Hatchback-Box tuned to 38Hz). The box can be sealed as well.
Amp: Kicker KX400.1
Car: 04 Pontiac Grand Prix

I have always built my own boxes. We have the house up for sale and don’t have the time. I have always read Q-logic was the best pre fab so I got the
QLH-1.7512SS.

Question: What sub would work nice with this combination?
I bought everything with the Kicker Comp VR (400w RMS) in mind.
Is there a better choice?

Thanks
Six
