Ok so I started looking at the re-q and stuff just to get a better understanding.
Do you have the re-q or the re-q5??
Make sure all the rca's are plugged into the correct places on the re-q.
The re-q5 has low pass crossovers, make sure these are set correctly. If the speakers are getting very distorted, maybe they are getting too much bass, and the subs are trying to play vocals, so the low notes are not hitting.
Make sure your gains are turned down before checking everything, so you don't all of a sudden play something full blast if it is corrected.
Make sure your subsonic is set correctly.
Check your subwoofer ohm load (the way you wired it) to make sure the amp is stable at that load.
That's all I can think of right now.
RE-Q not the 5 channel.
LPF is at around 100hz
Subsonic is around 25hz
Gains are full on the RE-Q
Subwoofer is a dual 2 ohm wired to 4 ohms, and bridged on the ZED
Subwoofer is defiantly not playing any vocals
Some of the guys on another forum are saying the the RE-Q might not be able to take the balanced signal from the BA amp and is causing it to act funny.

The -5 on the bass setting is killing you. Set it flat. The factory speakers should be able to handle the factory headunit with settings set flat.
when set flat, to zero, the stock speakers are distorting at the listening volume needed, to keep up with the subwoofer... that is the only reason it is set so low.

and what did you mean by
" or how i go about installing it without the capacitor you are supposed to use..."
are you saying it is to small? if so don't worry about it it is cap! glorified voltage meter which may or may not help you! you don't know till you try!
hell try it out! just hook it up to the front battery (temperately) and see if it fixes dimming if not then you know a cap is useless then lol
what i meant was, once i installed a knukonceptz capacitor in a friends system. it gave me charging instructions. it told me to use the provided tiny capacitor and attach it to the positive power wire. hold there for 1 minute, then connect the power wire without the tiny cap

so a 1000amp alt to support a 1k at 4ohm setup! i wonder how much current that amp is drawing then.
ya i am sorry dude i don't know why your lights are dimming then other then the amp can't keep up with the demand other then that you could always try to wire a cap in there..not like it will do much other then maybe prevent the lights from dimming b/c caps dissipate faster then a battery but then to charge back up... you know the deal with caps no need for me to explain it all it is a trade off i guess well you do get a cool voltage meter on a cap though lol!!
as for the high gains i can't help you there
sorry man
anyways get in touch we with me again some day!
Ya i'm baffled by all of this too.
As a matter of fact, I have a capacitor sitting at home, I believe it is a 1 farad Stinger one. Thing is, I have no idea whether it is charged or not, or if its been dis-charged, or how i go about installing it without the capacitor you are supposed to use...

What is the output form the RE-Q?
When measured with my multimeter set to DC voltage i got 0 volts on the RCA's which is good because that means that the signal is now unbalanced going into the kronos (or the other way around if i got them mixed up)
And Ken, as far as I know it's a 100A alt. The car is brand new with only 20,000km on it, so i doubt its an alt issue

Measure the preout voltage going to the RE-Q, and leaving the it and tell us your findings.
From the factory BA amp, we have 6V DC floating going into the RE-Q

System consists of the following:
• 2010 and up Camaro drivers side large stealth enclosure from Subthump
• Knukonceptz 4AWG wiring and interconnects and speaker wire
• MTX RE-Q
• Subthump T-Harness (used so that we DO NOT splice into the factory wiring)
• 12" Fi Q (dual 2 ohm wired to 4 ohms w/ all options and high qts)
• ZED Audio Kronos bridged @ 4 ohm (1000rms)
There are a couple things that seem to be off. For one, we are using the factory headunit and thought that the RE-Q would be perfect because of the bass restoration, and the fact that the Kronos needs unbalanced grounded preouts (as said by Steve from ZED). Now, due to the fact we havent installed any bass blockers on the factory BA system, we made the bass on the headunit to -5, mid @ -1 and treble to +1. What baffles me is the fact that the gains on the MTX RE-Q as well as the Kronos have to be set all the way up before any sound comes out of the subwoofer. Now the Kronos has 2 built in clipping indicators so I know for a fact that I am not clipping the subwoofer. I read that the RE-Q is supposed to boost the lower frequencies of the stock system so that there is no need to have cranked gains and such, or lose preout voltage on the RCAs....
So my question is, why must we have the gains so high on both the MTX RE-Q and Kronos to obtain proper sound?
My next issues has to do with the amount of light dimming on the interior lights as well as the amplifier. 4AWG wiring is used with a 100A fuse for power (at about 6 feet in length) and my ground cable is about 4 feet in length. The battery is in the trunk, and whats looks to be about 2AWG wiring is used for factory ground and alternator charging wire. Whenever the system is turned up, there is a significant amount of dimming going on with the interior lights (dash, dome light, etc.) but here is the catch..... The amp at near full tilt is getting 13V at the lowest, so it doesn't seem like there is a voltage issue what so ever.
So my question is, If my voltage is alright to the amplifier and batt, why is there such a significant amount of dimming?
Overall, I am very impressed with this system and would just like to clean up these issues so the owner can enjoy his finished system.
Thanks in advance,
Mike

Did you use regular sub box carpet?
BTW nice build....
On the door panels? Ya.
It's a pain to stretch but it turned out well

Any updates?

If you build the box right the IXL's can really soak up the power. If you don't just like with any other driver you can hurt them too.
I was thinking just under 2 cubic feet per chamber @ 33hz, with LOTS of port area

I dont see why not, as long as you send them clean unclipped power then it shouldnt be a problem. Set your gains right, watch how you roll the volume knob and have some fun.
Alright sounds good. I know the kind of power the SAZ is capable of, so I wanna be sure that the woofers will be up to the challenge, cause i know it doesn't take much power for these IXL's to get loud.

I plan on running two 12" IXL's off a SAZ-2000D @ 1 ohm. Electrical will consist off:
- two runs of positive 1/0 (one from alt, one from batt)
- three runs of ground to chassis in 1/0 (in the trunk)
- yellow top in the front
- NSB 75 in the trunk
- stock alt
Will the subs take the power daily? Goal is to make a 39.9 bassrace machine.

0.5 ohm stable for daily?

This all depends whether you are talking a daily setup or comp setup. I wouldn't do more than 5k daily.

You should have used fiberglass resin on that sonotube since its only made of hard cardboard. Couple layers will make it rock solid.

So what are you going with?
SAZ 2000D from db-r

Why ask if you still want to run it at 0.5 ohms, common sense would tell you run it that low and get an excellent electrical system and voltmeter. That is the only way to tell since every install is different and car acts different. Get the electrical you think is good enough and install it, if it doesnt hold up then buy some more.
Why ruin your equipment because you think running it that low will give you that extra umph when it wont, be smart and run equipment the way it should be. But if you insist then get a lot of electrical upgrades to back it up (those amps are already power hungry and would be stupid to run at .5 ohms).
A friend of mine has the exactly same electrical setup as me in a ford explorer and he has been running his AQ 2200d @ 0.5ohm daily and everyone said he couldnt.
1500rms isnt going to be enough for my liking.... thats why i wanna drop it down to 0.5 ohm.
Its hard finding an amp that will do good power @ 2 ohms (in Canada) without spending a shit load of money.
I can get either the Saz-2000D or T30001BD for $450

If the company doesn't cover it i wouldn't. you wouldn't want a Smokey surprise. However if you're burping and you know your impedance rise (if) i wouldn't worry about it. but you must know what you're doing. Also the amp has "soft protect"(basically like mute) and "hard protect" (shutdown, 8 sec cycle)
I plan on running a 15" Sundown Nightshade (v1) and its a dual 1 ohm.
Its either the t30001bd or a saz-2000d, but i want the amp to run @ 0.5 ohm.

Will this amp run @ 0.5 ohm daily with:
2 runs of positive in 1/0
4 runs of ground in 1/0 (to the frame)
Optima Yellow Top as starter batt
Batcap 2000 in the trunk
Stock alt (100A)
Has anybody ever run this amp @ a 0.5 ohm load?

The more time spent on prepping the enclosure (eg sanding, filler, and more sanding) the better the outcome will be in the end. I can't stress this enough... TAKE YOUR TIME. Looks good so far
