The Sundown does not have a clipping indicator correct? You may have been clipping it and not known it. You will be louder when you clip:fyi:

Bingo right here

Well the sundown was turned pretty far down, although cant remember how much. I had to keep turning it down because the bass was over powering my mids/highs. This AQ amp has to have the gain 1/2+ to get the same power that the sundown put out.

do you disconnect your battery? i know my head unit resets its setting ever time i disconnect my battery.

I did reset the battery but I went back and put it back to all correct settings.

thisand did you adjust anything on the AQ?

I messed around with the AQ but couldnt get anymore power out of it without the clip light blinking.

Correct nothing wrong with it at all. If you are screwed on space why not look into the Alpine pdx 1000. Thing will **** near fit in both hands. You can also bump the fuses up on those to do more power. I was looking at these but those things are mighty pricey. Havent seen what they go for on here though.

How many volts are your pre out on the head unit??

I wanna say 3volts which sucks I know...I will go check (I just checked and its only 2.5 preamp voltage...Im running a jvc dvd indash)

How did you set your gain when using the Sundown? Do the same for the AQ.

I dont have a meter so I adjust the volume to the max when I play it and then I adjust all by ear slowly until it sounds like it should.

May have been but I doubt it due to the sundown being turned down.

Aq 1200 is good as hell ive got one and id recommend it to anyone

The AQ amp may just not be doing well on your reactive load at 2 ohms -- many low impedance Class-D amps won't do so hot when wired above nominal.

You may want to look into a 2 ohm amp.

And if you have a DMM (digital Multi-Meter) try this tutorial: http://www.blazerforum.com/forum/showthread.php?t=8991
It really shouldn't take too long to do it and I 99.9% guaruntee that the amp isn't clipping though the indicator light says it does.

But for sure give me a call or if I don't answer shoot me a text and I'll respond pretty quickly, I'm in class most the day.

^^This. I have a feeling that mine does that sometimes but I do have one of the reverse gain knobs..

an m1000 would be good for your application //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif. Try changing amps or getting a D2 sub. The easier fix however wouldve just been to make something to cover the amps endcap (on the 1500)...sheet aluminum is awesome. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

i recently tried an aq2200 in my car and noticed the gain had to be turned up a lil higher than on my xp1400 to get output...might just be how the 2200 and 1200 r

With the Sundown the lowest input sensitivity setting is 6V, with the AQ it's 8V. So you'd need to turn the AQ up higher in order to match the input voltage from your RCA's. How much higher, I don't know.

x2 and nice to see another manufactuer be honest //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The AQ1200D will give you 870 unclipped watts at 2ohm. Most people are used to running amps well into clipping 10-20% without knowing it. The clipping indicator on the AQ amps is very accurate.

 

[michaellane 5,000+ posts]

the amp is rated at like 14volts so if ur car is not steadily running at 14 volts when the bass drops then youre not even getting 870 watts.

A w6 shouldn't need much power...

That pre out sucks. You need a new deck with higher pre outs or up the signal:fyi:

you should have gone with a smaller sundown.
