In a blind test they will sound absolutely the same. Go Google the $10.000 amplifier challenge, in such a test you don;t just swap out two amps, you have to measure at least power output. The entire point is that at the same power level you won't hear any difference between two amplifiers of different topologies. You won't hear the difference between your Crunch amp and that Crescendo IF both are set up to have the same output since the human ears are not able to pick up the actual differences in sound. Take a step back, take off your fighting gloves and brand goggles and re-read.

Your memory and capability of looking back is terrible. Thread got jacked when you had no idea what blind testing was. We don't look to start anything, you do that all by yourself.

Finally got them! First step was to mark my holes and add the inserts. This was my first time ever using them and it was definitely a painful process, but at least I learned along the way. I also kept a cutout in case one ever goes out I'll be able to run a single(with less power of course)

Billy Jack is the OP in this thread.

Everything bolded Fundamentally you act like a non-thinking brand loyal idiot. And then you will read that as me calling you an idiot which is not what I did, I said you act like one. Change how you act. Btw, I could bold nearly all of your posts. You have a fundamental problem with subjective and fact that is really screwed up. The WHOLE PURPOSE of all my posts in response to you are to get you to think instead of e-gurgitating nonsense that someone told you over time. What you thought you learned is confused and the only way to resolve that is to think. If you are incapable then just stop posting.

Your profound inability to accept the fact that you don't know what you're talking about is....impressive. That's not a compliment, by the way. I have absolutely no idea what to say other than, you need to do some research and real world testing before you keep spouting this gibberish. Just because you want to dicksize and rant, doesn't mean our newbies need to be getting confused by your walls of text full of opinionated nonsense. We deal in facts here.

You just highlighted again that you have no idea about testing, listening or thinking. Do some googling and thinking before you respond again.

Stop with the verbal diarrhea it is only showing your confusion. Instead of just hyping what you have perhaps open your ears for once and compare something. Nobody at all cares what you like unless you know why you like it and in order to do that you need to do open your ears instead of brainwashing yourself further. Seriously do a blind comparison, it will completely change the way you think about audio...or don't and continue to be the laughing stock of the forum.

I will admit that we (Billy Jack and myself) got a little off topic reminiscing the old days but the theory of gaining DBs was the primary. Nothing about this blind AB stuff was posted in this thread (which has nothing to do with gaining DBs) until Sean post what I quoted here. Thread practically derailed from there. I was going to quote and discuss with Adrain on topic but found it unnecessary after the derailment. Please understand, I'm not taking sides here. Just pointing out the obvious. I'm assuming this particular subject started on another thread ????

I don't think your gonna need that cutout anytime soon, unless you just beat it to death, with a lot of dirty power. Send it a good signal, and you should be good to go for the life of the vehicle, and then some.

The SSA SQSUV budget build is playing!

I got nothin', lmao I derped Guess I shoulda said original question.

That again is irrelevant to the conversation...

You've shown that the only things you believe and post are spoonfed information which of course means that is exactly what you want. I want better for you, but the first step is for you to want better for yourself.

I'm not sure how they are doing it, but the are slowing music and adding heavier bass frequencies to the music. More and more songs every day. Sounds like shit to me, but to each his own I guess. You're not going to find info on this subject on this forum. Just saying. I'd be willing to guess you know where to look.

Its an absolutely beautiful country both the scenery and the people. Hopefully this weekend we'll be taking a trip down to Mount Kilimanjaro.

those songs have bass from the original recordings Dirty Diana flexed the dash and drop it about 3" in my ground pounder with the four 15" Xcons on the Crown A3000gti..... that van was a piece of shit when I was done with it.... a good percentage of the body spot welds were ripped loose mostly from old 80's stuff

You suck at paraphrasing, perhaps you should quote. Then you'd see the idiocy in what you type. You are inferring things that aren't said and are forgetting to think.

More barf. What a surprise. I never said they were the same, that is idiotic I said you need to listen to them and you will be enlightened. Your ridiculous boneriffic statements will be squelched if you do.

Things don't just break. Well maintained equipment used with care lasts ages. I have amps older than me that still put in work the same as the day I got them. I'm not even particularly gentle. I just make sure to keep them cool, and well fed. If you're burning up amps in less than a year, perhaps you need to examine the only constant; the user.

Yes you are blind and confused. Seriously just do a blind test 1x on ANYTHING. It will shut up your idiotic brand nonsense. There are so many snake oil tricks in audio sales and you are succumbing to all of them.

I have my doubts that's going to do anything. A/C duct work is way under the dash. If by removing it you open up a hole in the firewall, I'm not sure it's allowed, especially in a class where everything should be sealed up. IMO all sealed up should be the benchmark. Cracking a window open or opening a door or opening the rear hatch to gain score are useless. As for the NVX versus old-school A/B and the China discussion....the new class D's take quite a bit of abuse, my plastic china shitboxes never got warm and they live in the tiniest space available under the rear seats. Using old A/B amps for nostalgia and bragging rights, ok, but if you say they are better than the new stuff, you're smoking the wrong stuff Same goes for saying you will be able to hear obvious differences in a blind test. Blind test meaning both amps are adjusted to the same measured output level. Now back on topic... Most of the gains will be in the enclosure. Huge ports, huge enclosures (screw rules of thumb, I have been using a 10 inch port for a 12 inch sub, in a 2.8cf box), orientation, bracing or lack of bracing. Heck, I retuned my port when switching up from 8 inch just by using software. It might not have been spot on but I gained an instant 0.9 dB, going from 150.0-150.1 to 150.9-151.0. Next up are car 'mods': removal of some interior panels and carpeting, bracing certain windows or doors. In my old Jeep bracing the rear-most side windows gained almost 1 dB. Seat position, sun visor position, taping up certain vents, this should be tested only after you run out of ideas or space for box improvements and after you have tested the previously mentioned car 'mods'. Most of the box ideas I found out by myself after listening to all the "oh, if you peak high you need a small box" posts on the SPL forums. I spent quite a bit trying to go over 147 dB in a 1cf box with a single 12 and a 6 inch port. Next step was a 2cf box, score went up and final iteration was 151.4 dB with the same sub / amp / power, 2.8cf box and a 10 inch port. 4.4 dB total gain by using a big box, big port, bracing rear windows, removing all side panels behind the backseat.

I run Kenwood head units. Had a few Pioneer units, but was never satisfied with them. I have the DNX9980HD and love it !!!

Gotcha. Had a pair of round comp 15s. Well, still have them in their original boxes somewhere in the shop. Traded them out with a pair of Blues Car Audio 15s when the first hit the market. Still have them playing in my mom's antique audio cabinet. Need to find a cabinet to put it those Kickers in.

Sound like an awesome setup. Ran a few Kicker products myself back in the day. Use to love to go up to Stillwater and pick up equipment. Dang, I didn't think the L7s were made in the 90s. I remember seeing the old square solarbaric (L5) drivers, but not the L7s ... need to call Jerry McCord and check on that ...

Genrally answers are offered to those who demonstrate a lack of understanding. You didn't need to ask to make it clear that you need the help.

By guiding someone to think as opposed to sooonfeeding them an answer, they can understand the process as opposed to a one time solution.

Uhh yea, that's what we where saying. I may have worded it funny, but I meant what could you alter to gain db's. For me it was floor mats, hatch, windows cracked, center console open, and glove box open. And you even said yourself, if I heard AB power It would be a revelation and that they sounded better, but now it doesn't? So which is it?

You never said no such thing, apparently you can't read your own text. What you actually said was "you didn't AB?.... you should have, it would be a huge revaluation to you," then I asked what AB was, and Arron answered, class AB amplifier. So now do you see the problem? And once again we where doing just fine, until you came in with your confusing nonsense, that only you can understand. Even Arron didn't understand what you where saying at first, so no need to come in now, and ADD words to what you actually said, to try and belittle me. And I have switched out plenty of amps, and it's bullshit you can't tell a difference cause sometimes, not always, but sometimes you can tell a difference if their different enough. And even if there was no difference in sound, there is plenty difference in build quality, reliability, style, and efficiency. And that's why I don't like the NVX mini amps, there week plastic little China shit boxes, that want hold up like some of the better built stuff. It's like saying a cheap ratchet from Walmart, will turn the same bolt as one from snap on, but neglecting to mention it will strip out the first time it's strained and the snap on will take a far bigger beating, and even if you do break it from normal use, they will stand behind it, where with walmart your on your own after 30 days.

Back peddle much? I love how you get on your period start shit on me then try and blame me for it. Same story different day.

How about just saying what you mean, instead of talking all cryptic, and secretive, so people can understand what the hell your talking about. And once again I will remind you, your opinions aren't facts, nor are mine. I like different stuff then you and that's fine who cares, but if your gonna call my stuff trash I'm gonna do the same it's only fair. And a lot of this stuff is subjective unless we are talking hard math so it's possible for me to hear or see something you don't. It doesn't make either one of us wrong or right just different. The problem is you have a problem with anyone having an opinion different then yours.
