i have a rap song that peaks at 4,5 and 11hz. It also peaks in the low 20s and again in the 40s. The 20s is the highest, 4,5 and 11hz is next highest. I would love to hear that song in the right box.

i sent the amp into clipping and was able to get a 139.26 at the kick @49hz and a 139.11 @34hz. It appears i have 2 peaks in my car. And again, this is not the tlab mic so scores here are lower that a tlab. I do not know by how much though because i have nothing to compare too. The amp itself, i like it. IT appears to completely do rated power. I have high rise evidently but power doesnt mean louder... I should have the other amp in hopefully by this friday but that also depends on me too. The company who made this sensor said that when the tlab reads a 179, their sensor barely broke a 170 so i do not know how close they compare at lower levels.

what was such a PITA? i have 2 knu distros right now didnt have to much trouble with them Getting the compression fittings threaded straight was a pain, but getting them tightened down to where they wouldn't come loose was almost impossible. Oh my god! You aren't lyin! I have their Konfused battery terminals... I already crossthreaded one battery terminal insert because of their impossibility. The idea is a good one, but unless you have 2 hrs of patience, it's ridiculous to the HIGHEST level. It took me just over 2hrs to install the positive terminal on my starting battery. That is just stupid. They better not come loose either. I liked everyone else's terminal's where they're held in by screws but couldnt find any that could accept minimum of 3 2/0 wires.

this is what i do- I use 0db tones on setups that can get the most potential out of the amp(s) without clipping. I sometimes go back through the setup process and use -3 tones so that i can get the most output potential for music. Whereas using -3 tones then playing music might induce some songs into clipping, i don't really suggest anyone do it as a fully reliable way to setup an amp. Reason being is what if you started to play some songs, especially rap songs that have constant, non-stop bass, these are just like fluctuating test tones in a song, which are just as powerful as 0db created tones. Since i listen to mostly songs like that, i have to use 0db tones when i setup my amps so i don't end up killin the speakers in the long run but if you don't listen to music like that, -3 should do u fine. But, i don't use this method as a way to create the best imaging possible. I use this method to get the most safe potential out of the amps as possible. If i want quality, i can adjust settings later as long as i don't surpass what the settings were at when i setup everything.

alright i'm back! Here are results- 2 AQ HDC312s wired at 1.4 ohm off of a single AQ2200D. Max frequency - 34hz. Measured at driver's headrest. Everything sealed and rolled up - 131.64 Window rolled down - 137.47 Output - 46.9V 8.7A Impedance Rise - 5.39 ohms Watts - 408w @34hz. Remember, this is measured at the headrest, not the kick or the dash. I still havent measured at my peak Fs which varies between 47-49hz. However at low volume, 34hz was louder, which is weird. This is not the Tlab mic, but something a little stricter. If someone can meet me who has a Tlab mic in Louisville, KY, the score will be higher. Oh, i did not feed it into clipping either. This is underclipped so power output would be a lot higher as well as spl. This is purely safe output. Amp is rated to do 740w clean power @4ohms and at 14.4v I did 408w at 5.39 ohms at 13.2v Sounds on par to me. When i get my other amp in, i'll measure impedance rise over the entire playable frequency range so i can see how much power this thing really is pullin because as of right now, it's not pullin hardly anything.

Ok guys, here i go- I'm sick right now so being bored just sittin around. I was playin the Wii but started to get a headache after grenades starting killin me, hehe. Anyways, as u all may know, one of the 2 amps is not going to be in the install for a short while so i am curious to see what i am doing spl-wise in this pure daily driver right now. I have 1 AQ2200D, stock alt, 3 Powermaster batts and 2 AQ HDC312s. Both subs are wired down to 1.4 ohms to a single 2,200w amp. amp is rated to do 2200w at a real 1 ohm load. This is what i am going to do- I don't feel like spending eternity out there getting every little detail out of this install as this will not be permanent anyway. I'm going to find a few frequencies that play the loudest and measure the spl AT THE HEADREST with LEGAL and OUTLAW measurements. After i get the loudest note, i am not going to recharge the batts or let the sub coil at all. I'm gonna go back there and measure the wattage output and impedance rise on this single note then i'll be done. IT's hella loud on the inside but oh so peaceful on the outside. Legally speaking, that's how it should be so you can enjoy your music anytime of the day. I'm goin out there now.

ah HA! now my mind is functioning, i understand now, okie dokie

save it as text? Wouldnt that have corrupted the excel format? When you hit save, that drop down menu right below the filename in the save as or save to window, it will let you choose various formats to save as. Hit the drop down menu and choose all files *.* This will keep the extension file .xls

my mind just can't process it, hehe. This is what i am seeing- chan 1 and 2 go out of the amp then come back in to 3 and 4 but because the line out is still plugged up obviously, it runs back into 3 and 4 again, again and again. I'm lost but if u say it works, then ya it's a great secret feature, hehe

well coming from the owner, that's great and weird at the same time... That's like running a line out from headphones into a mic input.. I've done that before to see what would happen and i just got a loud squeal.

i'll let u guys know hopefully within the next week. There are 2 problems here- 1 - why wasn't the amp(s) receiving a signal through the rcas? 2 - what happened to the slave amp to cause it to go up in smoke... I'll find out number 1, they'll find out number 2.

it's not super efficient but it doesnt take a lot of power to get loud? What is it, headphones?

update to this scenario- I finally got the master amp to work. There is, as i originally thought, a problem with the signal cables. But unfortunately, i've just gotten sick, figures, so it's gonna be a couple to few days before i can get back there and see whether the shop plugged them into the right output, verify the jacks work at all and make sure the head unit isn't damaged. The problem with the slave amp smoking... can't say until they receive the amp... I havent shipped it yet, i'll try tomorrow hopefully.

i could try but not the one that went up in smoke, hehe. I seriously would have.... but i was at the shop when we were doin testing. If it would have not went up in smoke.... we were gonna switch out the rcas and see if it helped... If it didnt, i was gonna run one at a time to troubleshoot.. but the smoke got me first. Their master tech is callin me tomorrow so lets see what he can think of.

well, definitely not low impedance. Even if it were, it'd be a LOT louder than what it was. That 100w amp i had in there when i was doing box testing was louder than this, that's how bad it was. A short, inside the amp is the only way i see it. Everything was looked over by me and a tech at this shop and found nothing wrong. And nothing with the multimeter or protection lights would disagree with me either. Apparently i'll just have to wait and see what they say. Well... guess i can go ahead and take pics of the install tomorrow before i ship em out. the remote wires are disconnected right now so if anyone sees that, don't blame the problem on that, lol

Audioque is already aware of this so while i wait for shipping delays, i wanna know if u guys can think of how this happened before i have to wait a week before they tell me. I have 2 AQ2200ds strapped together. The power light was always on on both amps so no reverse wiring there. They never went into protect. Voltage sitting at 13.5v Gain half way, subsonic all the way down, lpf at 110hz. Preout voltage 4v, preout maxed out on head unit, Sub output is turned on, bass is on +3 boosted at 80hz. I was on the phone with AW and everything was verified that everything was hooked up 100%. Even the resistance on the terminals read 1.4ohms so everything was perfect. Turned on the stereo, had to crank it very loud just to get an "ok" sound out of the setup. What did it sound like? sounded like the subs were out of phase... But that couldnt be because they are wired in series, then parallel so out of phase is impossible. We checked the rcas, everything had a perfect connection. We left this song playing for about 15 seconds.... All of a sudden, the slave amp just completely started smokin.... BAD. The entire underside of the amp, all vents on the bottom and both ends of the amp were venting smoke. Immediately turned the car off and disconnected the remote wires. The master amp is fine but both are being shipped back... So, what do u guys think may have happened? IT is a signal issue but how could a signal issue cause that kind of damage?

BIG PROBLEM!!! Another delay. I can't say what happened because i do not know, all i kow is that there is gonna be about a 2week delay minimum on this project. One of the amps just went up in smoke due to a possible signal problem. I can't say anything further until i hear something after they receive the amps.

we have ADT\Brinks Home security. Basically, we have sensors on the doors and windows so if the sensor separates(door\window is open), it will trigger the alarm. We also have 2 motion sensors that are very sensitive. If you have any pets in the house, remember this line and i'll get back to it. Our alarm has a stay or away mode. If set to away, all sensors are active. If set to stay, the motion sensors are disabled so if you have pets, this is what you would want to set it to. When setting the alarm, you have 30 seconds to get out before it's fully active. Once active, if you open the door, you have 30 seconds before the actual alarm goes off. You cannot stay in the house when the actual alarm is going off. It's so loud... it's... trust me, no way. Anyway, if you do not disable the alarm before the real alarm goes off, the police are dispatched immediately. Also, you will receive a phone call requesting that you tell them a secret password that is different than the alarm itself. If you do not know it, feel sorry for you. There are other sensors tied into it to. You can get sensor so if the smoke detector goes off or if a carbon monoxide detector goes off, the fire department is immediately dispatched. I speak from experience... false alarms though, cleanin out the furnace, hehe. don't know how much it costs but there you go.

plus i'd like to see your gas mileage afterwards.

YES!! I get to be the first to respond to the 56th thread just like this!!!! Hmm, let's see comparing basics- 2 12s to 3 12s to 3kw to 4kw. 2 12s off of 4kw= x amount of output 3 12s off of 3kw= x amount of output. it takes double surface area or double power to potentially gain 3Db. So, going from 2 to 3 12s potentially is a 1.5Db gain. Going from 4kw to 3kw is a 1.5db loss. So, lets say for example 2 12s off of 4kw is 150Db. Add one more 12 adds 1.5Db, but subtract 1000wrms and you have lost 1.5Db. Result- Either setup should potentially do the same. But i prefer the 3 12s because that is a better efficient setup.

it kinda makes you wonder after this story if another sequel's story would ever succeed.

has anyone heard of the guy in Selma, IN that is pumpin oil directly out of his backyard? It was on the news today.

Ok, got my batt in. I've been workin pretty much all day... I am STILL ALMOST done with the bass area yet again. 1 freaking battery terminal took just over 2hrs to install. A word of advice, if you do not have patience, do not buy KnukonceptZ Konfused terminals and put their Kolossus 1/0 cable in there. I have had nothing but trouble with that damn terminal. So, yet again, tomorrow, all i gotta do with the bass area is run the ground from both AQ amps and ground my battery solenoids and parallel all ground terminals on batts. That's it! Then of course spray out the entire area so nothing it loose back there and start tuning the amps. I'll try to get some progress goin for install the Image Dynamics but i can't promise anything. Oh, i'll be takin pics once everything is grounded. I WILL MAKE A VIDEO BUT AFTER I PURCHASE A NEW VID CAM.

i like white tires a lot

he has 2 memphis 1500ds. I would look over your vehicle before deciding on adding that 2nd amp in there. You will need minimally- 200A alt approx 150aH worth of batts just in the rear of the vehicle. This does not include the batt up front. Failure to meet that will result in very short run time at recommended voltage levels unless you listen to a lot of music that rarely has bass, lol. now, factor in the space you may have left.
