Anybody able to get some serious bass from a stealth box?

That being said, you will need to look at your sub amp, and make sure not only the volume is up, but the filter is set at an appropriate level. make sure you really don't have too many higher frequencies going to your sub ( you will know when you can make out the words the artist says). You want to get it where the sub is capturing the bass that the speakers left off at.
Also, check your bass boost and make sure it is up. I would also see your head unit, and see if the bass is up, as well as check if there is a separate sub control on it.
Now also remember that your box will also make a difference. If you go with a sealed box, like the stealth box are, they will sound tighter, but they will need more power through them. If your box is ported, The bass will be a little looser, but there is a lot of air running through them, and it will sound louder. This is a popular choice with people that listens to Hip-Hop and electronica-type music. There is also the bandpass box, which includes a sealed and ported elements that will make it THUMP!

Be careful when adjusting the amp. Ive never seen a sub amp with "volume" on it. If youre referring to "gain" do NOT turn it all the way up.
Do not use bass boost.
Youre biggest problem is your box size and type. Some of my little brother's friends have P1s on **** for power that are hitting harder than my Fi Q on 1500watts rms because they are in a big ported box.
Going to a ported box would offer you the biggest gains in output you are looking for. A sealed box will NEVER be as loud as an equivalent sub/amp in a ported box. The ported box will get alot louder and require less power to do so and be easier on your sub. Especially when it comes to the low frequencies

What does everyone think of that autotek amp? It seems like the deal of the century! I've never used them but heard nothing but good things about them.

That's the one I bought. My amp powering the other speakers in my car is also an autotek (came with the car) and it's done nothing but good things. I could only imagine that the one I just ordered will be just as good. I got it from onlinecarstereo because a LOT of items are on sale.

You are kind of right. While putting the amp up all the way could lead to clipping, you can put the volume up high if you have adjustable sub controls on your receiver, or if your amp comes with an remote.

I noticed the stealth box I bought off a guy here, hmm, was not as he stated when I asked him the internal size. He stated, it was .5 cuft. My woofer an Elemental Design 10" requires .4 cuft min optimum .5 cuft for a sealed enclosure and 1.0 cuft for a ported design. Ok, so when I got the box it looked small inside. I measured it and it was .26 cuft.!!! Well after I emailed the guy he says, "I built it to subthumps specs. they sound good for my 10s." Well my tape measure and math skills usually are dependable. So, I spend probably $50 more bucks on fiberglass and such. I mocked up out of posterboard the enclosure to use the rest of the complex angled space behind the box. I then fiberglassed it up which took more work then I expected. It was worth the effort, I got the interior space to .51 cu ft. If the industry boxes are all as small as the one I got that would really reduce the efficiency and effect the frequency curve of the speaker. It would be the equivalent to lowering your car the half *** way, cutting the springs. The speaker in a box with a too small a volume behind it will not have the correct movement. The air pressure will peak to early and effect excursion of the cone. Hence cut the springs car is too stiff and you lose suspension travel, too small enclosure and your woofer is less effecient and has less excursion.
I can't imagine in a stealth enclosure you could find the volume for a port.

Speaker for the enclosure I just read your post from 2 1/2 years ago. I can't say how the woofer I just bought from them stacks up. Maybe its junk? I'll see.
But information thats 2 years old is maybe perisable? The would be saying that a company can never improve on their product. That is why they come out with new models right and as far as the specs for the speaker. I'm not sure whats missing?

Better would have been Peerless SLS run by a single amp channel. Dump that Monsoon crap.

Where did you get the idea I was using the monsoon still. I'm running a 600watts (rms)MTX Jackhammer to the 10, 125 watts (rms) a piece to the 6.5's subs for a rockford 2 channel and driving the 6.5 compnents and 4x6 infinity plates with a 4 channel Soundstream at 75 watts (rms) a piece. The source is getting cut up and distributed by a 24 dB/Octave Linkwitz-Riley Alignment Crossover. That way the amplifier and speakers only deal with the frequencies they are responsible to produce. Power is nothing without traction or in this case distortion. I'm sure you woould have done it differently, but I'm writing the checks, so I'm making the decision.
