15 xxx not impressing...what could it be?

Definatly consider buying another sub...it is not worth you being disatisfied with somthing that can be easily remedied with a simple addition utilizing the same power.

I've never heard of reconing a sub onto a different motor...that is where precise calibration of all points on the surround and motor a required in order for the sub to perform properly.. most manufactured subs on the market don't even come close to the tight tolerances required for a solid built sub, due to time limitations in the production process. I had a dust cap re-glued onto a 12" sub before, and never had any mojor problems.

You couldnt make a 13" w7 loud lol. Should gave it more power buddy those things cany get saucy loud.

I would first remove the sub from the box immediatly(possibly with box if possible)...bring it in the house and hook it up to your home theatre set-up, and see if it still makes that noise...if it does ...then there is somthing wrong with the sub, and needs to be inspected by whome ever re-coned it...this should quickly solve your problem instead of testing out your entire system un-nesecarily. If the sub sounds normal...then check all your processors and connections and settings etc.

To the OG poster i would try a new box. You box is kinda small my sealed box for my 12" was 2^3 so 2.2 for a 15 is kinda pushin it try going ported 3.5^3 to 28
you will love that

Since you brought up the term SPL and we all know SPL is a numbers game it should be proof enough that you are wrong when any one of us guys who have been in this hobby for years can post up numbers of single sub setups that were great on the mic. What's even better is that many of us have used daily one sub setups tuned more for SQ abilities that could still shake you silly.
Any one of the knowledgeable car audio guys on this forum could build a capable single sub setup with 500rms going to it.
Painkiller - The response of the 15" XXX is pretty good in 2.5net sealed but you're saying it isn't loud enough for you so what you really need to do is port it. 3.5-4.0net would be my suggestion for great SQ with enough SPL ability to shake things easily enough. 4.5-5.0net if you wish a tradeoff of some boominess for increased SPL.
Also, go over all your settings and make sure everything is correct. Most decent HU's have enough preout voltage to get a D2 working good in daily applications so with your change in HU's making a difference it makes me wonder where your current HU is at in terms of settings.
oh man, that guy is getting owned.
i had a 13W7 and with the 1000/1 amp i hit 140.7 on TL and thats with a wall built for show purpose so hardly anysound was getting into the car. it gets plenty loud! haha
also, i have seen a 15" XXX hit 145 on TL. cav2nv420 had it so pm him, maybe he can tell you about the box he used. i think he had 1500rms going into it.

It's too bad you guys are giving advise, that possibly might be beyond the persons ability to successfully propogate, I advised him from the point of view of a quick fix...not trial and error of up-teen different boxes before the box finnaly hits hard.

Before you go and spend a ton of cash, try reconstructing your box. Try and go ported if you can (people here will help you design a box and I don't think you will have to build up-teen of them before you get great results
) and tune in the low to mid 30's. A ported enclosure will be more efficent and maximize your amps output. I think these drivers were meant for a ported boxes and you might be pleasently surprised with the results.

are you using the correct RCA lines from your deck? I made the stupid mistake of hooking my fronts to the sub amp and it sounded like pile or Pyle haha.
quick check without removing your deck is just go to the subwoofer control and turn it off, if it still plays then they are wrong.

You're a retard. They've been giving much better advice than you have.
