Ok, so here is my situation. My current set up isn't satisfying enough for me.

I currently have

AMP: PPI PCX2200 800WATTS RMS BRIDGED

BOX: PORTED BOX BUILT TO JL DESIGN CP112G-W1v2 (H 15.25 in. x W 20.50 in. x D 15.00 in.) so roughly i think i have around 2.5 cubic feet of volume

SUB: 12" KICKER CVR 400WATTS RMS

CAR: 1997 BMW 318IS WITH FOLDED DOWN SEATS

GOAL: Good LSQ that'll kick some street Ars

Sub that I'm considering to upgrade to: All single 12'' I want to see which is the best/loudest LSQ sub out of these since i've heard none of them and have read good things about most of them i've gotten myself rather confused. price on sub is not a questions will be working with the amp and box i already have.

RE SX

FI Q

SI Magd2

ID Maxx

DD2500

Mach5 MAW if they do have a 12''

CVX

Your caps lock isn't satisfying to me.

Out of your list, there are only 2 you should be serious about the Si Mag and the Q. Currently it isn't possible to buy a Mag so that leaves the Q.

so the Fi Q would out compete the DD and the RE?

sorry about all the caps just wondering if anyone has heard of TC sounds

Loud SQ has very, very little to do with the substage...because it's a lot harder to get your front stage up to the level where it needs to be.

It sounds like you're talking about SPL for rap, which is different (especially considering you made no mention of anything other than subwoofers).

If you're working with the box you already have...I wouldn't bother. The enclosure is where I'd start to make changes.

so how would you change the enclosure?

Ya I hear ya on the CVR 12. It doesnt have much Xmass and basically its not a loud sub, but for SQ in a sealed enclosure it works nicely and the price is cheap.

i'll agree with you there crunch1

how do the SSAs stack up to the list i put up?

You need to address Jim's comments first. You are asking for SQ on one hand and then completely not on the other. What is it, do you want a loud sub or one that blends with your front stage.

so i can have one or the other?

Well in the box design realm they are at the opposite extremes. You don't really choose between them but where in between, but there is a direct trade off.

You do need a different box no matter what you do.

i'm looking for more spl than sq then... I don't understand why i need a new box... haha i spent like a bill on that box

found an SI mag on ebay for 365 worth it? would i still have to toss my box for a different kind? If i do then what kind of box do i need?

The box has to match the sub, I don't care if you paid 10G's for it the wrong box will make anything sound like crap. Major crap. I would imagine most of your problem is the box in the first place.

so for the si magd2 i'm looking it it'll require me to have a 2ft^3 box ported.

so basically my box is too big right now.

am i right?

You can get by with the 2.5 on the Mag. Many people are running them in 2.5, BUT for OPTIMAL results, go with what Nick suggests on the site.

I've heard plenty of stinking loud Comp VRs. Don't buy into all this Xmax talk. Xmax tells you nothing about a drivers capability. God, when are people going to get over this?

So can the SI mag d2 out hit a RE SX?

*cringes*

Well, at least we know where you stand on the SQ/SPL thing.

That's totally box dependent. I've seen both Mags and SX's do well in pure SPL installs, one may work better for your specific situation but that's something you'll have to see for yourself.

So can the SI mag d2 out hit a RE SX?

The Mag D2 is the end-all-be-all of subwoofers. That's my opinion and I will stick to it for life.

sorry Tirefryr but I dont agree with you there. I have comp a set of VR's that are not that loud. before you go there they are in the optimum enclosure and supplied with as much clean power as they can handle.

Optimum enclosure as recommended by Kicker or optimum enclosure found by trying many different enclosures and a Termlab?
