Can You Help Me Find Out What Went Wrong?

posted this on some other forums, but didn't quite get the help i was looking for...

Pics are in http://www.cardomain.com/memberpage/658218


Well, the injured souls are:
a PG Tantrum 1200.1 that is COMPLETELY blown, i'll get pics in a few days.
my Directed 2400d (again ) which keeps going into protect.

here is the curious part......it was caused by a cd .

My friend with the PG was driving last night plying a newly copied cd when his amp cut off and filled his trunk with smoke, needless to say not a fun time. Today he hopped in my car and grabbed the same cd since he didn't get to listen to it the night before. Well he put it on the same track that he left off at and not 15 seconds into the song my subs amp cuts out as well (at least it went into protect instead of blowing like my firend's. his amp is far beyond repair).

so, after investigation we could only narrow it down to the cds/rcas. The fuses on the distrobution block are fine, and the component amps one the same distro are fine in both cars, so it can't be power. Two different setups with two different high quality amps so it can't be defect. Also, now my amp will play ANY cd, burned or store bought, for about 20sec and then go into protect, even though it worked before.

The only thing i could think of, and this is pure speculation, that there is something in the recording of the cd (unintentional i'm positive) located in the bass reigon because both amps have SSFers on and both have x-overs set about 80Hz, plus ONLY the sub amps were harmed.

anyone else want to take a shot at what might have caused the problem, or do i really have a phantom cd. Hopefully i will have more info when DEI repairs my amp and tells me what was wrong.

 

2002 Hond Civic EX:
Stock HU with generic LOC
Diamond Audio S600s comps on a Lanzar OPTI 500.2
(2) ED 12A (flat cone) in 4^3 @ 32Hz on the PG 1200.1
stock alt and a red top

0awg runs from the battery under the hood to an Audiopipe d-block giving each amp 4awg power, PG had a 200a fuse (too large i know but i was only thinking a short was possible not this) and 100a on the Opti. Subs are in series-parallel to 2Ohms. RCAs run from LOC to Lanzar, out of the Lanzar into the PG. The whole setup ran 100% perfect for over a year until track 4 of the burned CD.

2004 Chevy Trailblazer:
Pioneer 940MP
Diamond Audio S600s on Opti 500.2
(2) 12" XXX in 7^3 @ 33Hz on Directed 2400d (wired to 2Ohms)
150a stock alt
RCA run for each amp off HU
2 yellow tops

0awg runs from under the hood to the batt in the back...(to be continued, i have to go to work)

 

....(i must be blind because i can't find the edit button, anywho) batt in the trunk is grounded with 0awg, then a 4awg line runs about 2' and is split into 2 more 4awg, one for each amp. the DEI has a 150a fuse the lanzar a 60a AGU fuse. My setup worked great for about 2 months, then i blew the amp's power supply because iwas stupid, then it was fixed and worked great for 3 weeks until i put in the cd on track 4. Do i find it very had to believe that a cd could do this, sure, but i dont know why we each had problems on the same track on the same burned cd.

My amp seems to be fine because now it plays for a little just fine, then goes into protect, i thought about the resetting idea and just haven't gotten around to it yet (i've been at work and only thought of it late last night).


So both setups were quite different in wiring and fuse ratings, both had good quality amps that broke, and both went bad on the same cd on the same track. I am 100% confused why his blew and mine went into protect and why each one went to begin with.

 

Hmmm...never considered that it could be a single "note" recorded (or mis-recorded since the origional is fine) higher than all others. His gain, knowing him, was probably cranked; I myself would have thought to have been set correctly, but looking back it did happen when i was in the process of raising the sub-out from -17(normal) to 0(very rare). How high could that "note" have been recorded?

Would this possibly explain why my amp will play fine (i say fine, but i swear i can hear it extreemly slowly lose output before it goes into protect. also could be mind games) for random amounts of time, usually dependent on volume, and then go into protect? then come out and repeat the process? Should i try "resetting" it like seth suggested?

 

and thanks a lot Seth and Chris (and anyone who joins later ) these are exactly the answers and help i was looking for. Most people just said "that sucks" and looked at the pretty pictures, lol.

 

maybe i should be a bit more clear. MY gains are set at 1/4 with a 6.5V input which according to DEI is correct. I also hardly ever run the amp hard and it is basicly brand new so i know there isn't a lot of wear and tear on the amp. So, i'm not eliminating the option that the cd did it with a clipped tone, but i know for a fact i haven't been running a clipped signal.

Also, something else i dont think that i have explained is that when i say it cuts out and goes into protect, this is on cds that i know very well and are both store bought and copied cds. It never had any problems on these cds until this mystery started.

Now with that said i will of course reset the amp and see if that fixes anything (have to wait till tomorrow obviously), if it doesn't then there is no point in resetting the gains since it will go into protect so i'll just send it to DEI for repair. Didn't mean to sound rude or anything in this post, i just dont think i explained some things well enough. I know about basic clipping and installation issues and have pretty much eliminated then as the main cause (like i said, i know my buddy pushed his amp hard), i would hope i'm not that limited in my knowledge

 

it was some latin house cd, i dont know any more because it was my firend's. I do know that it was a copy off an origional, but the origional was never played in a "system" before and they person who copied it is known to make really shitty copies

 

thanks seth, you were right all i needed to do was reset my amp. i also called DEI and they thought they same that all you did, there was some garble of tones or something that clipped my buddy's amp to hell and sent mine into protect. But everything is fine for me at least

now, after you guys saw that damage, and considering the situation, do you think PG will be willing to help my buddy out even though he got the amp over a year ago off ebay?
