I have a 12inch stealthbox built for my trans am. It is between .7 and 1.0 cubic feet. (Yes, that is corret, it is built for a 12 inch but I could rebuild it into a 10 inch box)

I have this amp: Sony XM-SD61X
300 watts @ 4ohms rms, 600 watts @ 2 ohms rms

Now I need a Sub. I originally had a 12inch kicker competition in the box with a lanzar vibe amp. So i was thinking about going with a comp VR 12'' sub this time.

Should i go with the Kicker comp vr or should I pick something else?

 

The new Comp VR's are amazing! I highly recommend them. I am running 2 in my GTA in a 1.0 cubed box, sealed with an Orion XTR 1000D and they will pound. Deep, tight bass and the speaker is built better than any other comparable 12 on the market!

 

i've got 2 10 inch kicker comp vr's in the well of my camaro and they are amazing! they are powered by a fosgate amp putting out 300 watts RMS. very good subs.

 

what did you do to make it fit a 12" sub? did you just cut the hole bigger to fit that?

 

I built the box myself and I built it around a 12'' sub I had at the time. It was hard but there is definentally enough room for a 12 that isnt very deep. Im not sure if it is a good idea to use a 10 or 12 though with this small a box, can anyone chime in?

 

Different subs are designed for different sized enclosures. Some do great and are manufacturer recommended for small boxes, others need larger boxes. A comp VR 12" sub is recommended to go no lower than 1 cubic foot in a sealed enclosure. The 10" version is rated for no less than .8 cubes. If you have your heart set on a VR, you could probably eek the 12", but wouldn't get maximum performance from it, the 10 would probably sound better.

For a little more, may i suggest an Image Dynamics IDQ 12"? They are a few bucks more than the kicker, but will go down to almost half a cube, with a max of 1.0 cubes. I think it'd be a better fit for your car, plus they have a better efficiency than a comp vr. This means you will need less power to get to the same volume level. They handle a smidgen less power on paper than a comp, but will outperform it because it can get just as loud with less power.

SQ is a matter of opinion, but i've heard both and i feel the ID's are a bit more accurate than the comps.

Check 'em out at least
