Has your amp ever 'missed' it's cue?

[Frankensuby 10+ year member]

If it is supposed to be Queue instead of cue...oh well.

Anyways, this morning I got into my car and started it up for it's 3 minute idle warm up. While sitting in it, I thought to myself "Man, my subs really overpower my speakers even at low volumes, I can't even hear the speakers right now". Keep in mind I had been awake for only 7 minutes or so. Also, this amp was installed last night in haste, no tuning done or anything, so it is rather quiet right now.

I promptly realized that my speakers were in fact just not on. WTF?! I question myself naturally. Going to the rear trunk I realize that the blue LED telling me that my Xenon X100.2 is on...is off. Yet, the internal red light is on inside the amp (has always been on since I connected power to it yesterday, and played fine). So, I just pull and push on some wires....nothing is loose. I decide to shut my car off and restart it, just to see.

It turns on no problem, with the usual quick static 'clip' that a repaired HU makes after it's Pre-outs have been blown (Curse you Pioneer! And myself...I'm the retard who blew them) . Speakers play fine, no loss of power...they act as if they were playing a trick on me, sounding just as clear and precise as any time before.

So...has anyone had their amp sleep on the job like me?

yes I don't know why but my sub amp takes a little longer to power on while my speakers play. Weird but lags for like 15 seconds then just turns on. Doesn't really effect me but I wondered why it does this too.

nope.

Never had one not turn on, but once in awhile my subs will lag behind my comps or vice versa.

The word you want is the one in the title, not your "correction" in the first line of your post.

Cue is a signal to begin.

Queue is a line of people.

Back the the amp; It was weird. I just replaced the Speaker level amp from a Xenon 200.4 to a Xenon 100.2. The amp had power, it just wasn't turned on. The sub AND speaker level amps use the same Remote signal wire, and the Substage was on. The only thing I can think of is that my remote wire might be loose, or I installed too much wire into the input and it's mostly rubber coating touching the input. I did notice my speaker level is lagged behind the sub level bu roughly .5 seconds...not a big deal. it is because of the internal processor reading the speaker loads and adjusting, it happened on the X200.4 as well.

I think that actually happened to me once. But that was before with my old crappy head unit...hasn't happened since I got decent equipment and reinstalled everything

some amps also have a longer turn on delay.

Sorry to thread jack, but how do you blow pre-outs?

 

[helotaxi 5,000+ posts]

^^I had an amp go (selector switch on the amp got bumped to an in-between position) and shorted the RCAs together. End result was a torched trace on the HU PCB and no more RCA outs.

Lol, by being a retard every once in a while. Way back, before I had any Xenon stuff, I had a Sony X-plod in a sealed box (Flamesuit on). I borrowed a Bazooka amp (shoot me again haha) and was test tuning on that amp. I had actually ordered my X600.1 the day before, and was learning how to tune on less expensive equipment.

Anyways, I had the amp hooked into the power wire, but from pulling on the amp to access the terminals, I had wiggled the ground wire loose. While trying to get a DMM reading, the ground momentarily jumped out of the terminal...while the Pre-outs were still hooked up. The amp needed to find a ground somehwere, and it found it by jumping through the RCA's into the head unit...which the Head unit promptly said "F this!" and the pre-outs went kaput. That's the brief version //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

When i mean that my amp didn't turn on this morning, I meant I let the car idles 2 minutes trying to figure out what was wrong in the trunk. The amp turned on immediately when I restarted the car.

Sounds like a hiccup in the impedance circuitry that just muted the amp.

Well, whatver it was, it did it again this morning. This time I didn't touch any of the wiring in thr trunk, and just restarted the car, and it worked fine.

My guesses are as follows:

Theory #1 : When the car gets cold, the battery discharges somewhat. Since this is morning #2 below freezing, I could imagine that the battery doesn't have enough voltage to start the amp and send enough signal through the remote to turn the speaker stage amp on. The lack of constant signal power through the remote might be throwing the amp into protect. The blue LED that tells me the amp is on and running is NOT on when this occurrs.

Theory #2: This sort of goes hand in hand with #1, in the fact that I believe maybe the amplifiers capacitors are discharging, which when it is signaled to turn on, and then the power is subsequently used to turn the alternator, the amp does not have enough juice to turn it's internal processor and load detector on, so the amp goes into a protect mode.
