MTX's newer models subs are fantastic. However, the 9500 is a completely different beast from the cheap Type-X you had. It can withstand serious punishment, but it's not going to be as fast as other models (7500, 8500 etc). It's more of a deep-bass sub. It's a sub that'll last you for awhile, and that will of course pound, and those are the TWO reasons most people buy it, but it IS kinda a muddy sounding subwoofer. Just remember to give each of them 1000 watts if you want maximum performance out of them, don't skimp out on watts with those subwoofers.

Kicker L7's are pieces of crap. They pound, sure, but they sound like utter crap. Square subs designed solely for pushing air, not really making it sound good. The W7 is a good sub, but it will sound TOTALLY different than the 9500\Type-X etc, either you love it, or you hate it, because you will find some music that you loved before with you're Type-X, that you just HATE with the W7, and some music that you love more than ever due to the notes it'll pick. It just goes low to the point where it almost sounds like unrealistic bass to me, that's the only way I can put it.

Also, you need to remember you are simply going to have to upgrade you're alternator if you got two 9500s, or two w7s etc. You're alternator won't be able to remotely keep up with that power, even more so at a what I would say unstable 1 ohm on that rockford. I'd put a fan on the amp actually, 1ohm runs REAL hot. But realistically you are maybe at max doing...what...1200 watts? You're alternator just can't pump the juice that amp needs. In all honesty, I see no need to go with 2 of those unless you are willing to fork out the cash on a new alternator, and some serious sound deadener.

You seem to just want pressure...why not just go with a high-quality 15" in a big box? You can run it at 2 ohm then and give it plenty of power.

Oh, but on the topic of 9500 vs W7 (don't even bother with Kicker) I'd personally go with the 9500. The w7 will sound better, but the 9500 is going to take a LOT more punishment. Just remember...you get two..you will be under powering them, and subs like that don't like to be underpowered. And no, the sledgehammer enclosures do not suck. They are built to match the MTX sub you buy them in. They are fantastic for a pre-fab box, whoever told you "they suck" has more than likely been buying the bottom line 4500 MTX crap (every company has that low-level "loudest on the block" crap that is terrible)

You get what you pay for. And I noticed you said "clean" generally, a subwoofer that has a voice-coil that requires over 1000w or at that, is NOT going to sound clean as a more efficient woofer, aka a MTX 7500\8500 will sound far cleaner than a 9500, just by design. Just as the W6, will sound far cleaner than the W7, any day of the week.

Why don't you go to a local audio shop and listen to these subwoofers? I would NOT buy a W7 or 9500 etc without listening to them..or any sub for that matter.

And the final thing. In the past, up until 07, MTX was crap. Boldy put, utter crap. They they redesigned their woofers and started putting out subwoofers that sounded amazingly good for the price range. Since then, they have been going up. The upcoming TR models are supposed to sound fantastic (though those would not suit you're amplifier) and they just keep getting better. Make sure whoever you talk to on the topic of MTX is actually up to date and has experience with their new woofers, not some JL douchebag who is biased and doesn't listen to any woofer but his own and says every other subwoofer out there blows but his.

Thanks Jesus!!! That was an amazing write up. Actually it was on a sound forum in 2005 when I read that those boxes suck. If you are right about 07 being there revamping time, then I will take your word. I do want clean bass (I listen to a lot of metal, rock, dave matthews... etc) and I want it to be clean and efficient...but I also listen to Jay Z, Eminem (sometimes) and Drum and Bass, and I want to have the ability to POUND.

I want two woofers so that each woofer is doing half the work to produce the same amount of bass as one woofer. I had two Alpine Type X's in my Magnum 2 years ago, and it sounded pretty good. How much would a new alternator run me and which ones should I look into? I read the bench test for the Rockford and I believe it said at 1 ohm it can produce over 2000 watts. But I will also need to buy a new battery and alternator.

I do NOT want a 15...because those, to me, seem and sound sloppy (the ones I have heard). Do you think the 8500 would be more suited for my application? I want basically the best of both worlds. If the 9500 can perform cleanly enough in a ported application, I would go that route.

The whole interior of the FJ is sound deadened as well.

Again, thanks for the insane write up!

Well, mines sound deadened as well with over 330sqft of dynamat extreme, and bunch of panels filled with great stuff and R-13 insulation, It still rattles with my 2 12". I think the 9500 will suit you fine, the main reason I'd recommend it is because of it's durability. And yeah, 15" are sloppier, but I wasn't sure if you just want air-pressure or good sounding bass.

And yes, the Rockford can put out 2k watts, but I was saying 1 ohm is VERY hot, I'd think about putting a fan the amp to cool it down, and 1 ohm it won't be very efficient, so yeah you pretty much need a new alt\battery.

Btw, if you want to know what happened to MTX. For a long time the grand-father of the company owned it, and was directing the sub woofer development\amplifier area. Then he recently passed it on to his grand son, now clearly a grand son is going to like bass more than a 60 year old man right? Well, apparently the son turned the company around, as now they are doing MUCH better. I wonder if down the road they'll make a custom enclosure w\ sub woofer like they do for other vehicles.

If you want to go above and beyond, aka get a sub that most people have never heard of, nor heard in general, but will blow most anything out of the water. Check out Ground Zero. Expect to pay a lot more $$$, but my god are they incredible. Really big power hogs though.

Here's a vid of one of their little tens.
YouTube - Ground Zero hydrogen 10" sub

Only reason I didn't get them is I like to buy subwoofers that I can find\replace locally, and uh...the good ones are really expensive.
