Well here's to it still not working correctly.. 30mins into my drive today pushing the amp and it went into protection again. I am at my wits end with this thing. As for thermal means it had doth the pads and the paste stock. I reassembled it the same way thermal pads and compound. I find it odd tha...

Ok so back onto the amp... I tested out the thermistor for the fan and no good.. Fan still didnt come on. I touched up the solder and ran the amp at 2ohm for quite some time and got it good and hot. Fan came on and was working. Got the amp back installed and took it for a drive and pushed it real ha...

So I took the amp apart again. Cleaned up all the fets and applied some more heat sink thermal compound again. I also took out the fan and tested it as well. Fan worked outside the unit. Took a drive and tested out the amp. I am almost 99% positive that its thermal related. As soon as the amp starte...

Ok so here it is quite a while later. Blown Fets. Burnt transformer. All fets replaced with identical replacements. All old heat sink gel cleaned up with isopropyl. Heat sink compound reapplied as if they were all CPUs so its not too thick. Amp still shuts down and goes into protection mode at rando...

Like the Title says. I blew my Xenon 1200.1 and was in the process of replacing all the FETs and also noticed that the power supply coil took some sort of a hit and looks as though it shorted. I am trying to find a replacement but without knowing any specs on this it seems rather difficult if not im...

Ok amp is back installed and working flawlessly. It seems to actually work better than before... The fairchild Fet replacements (FQA30N40) fit perfectly and function perfectly. I personally dont notice any difference in the amp with the new Fets. As for the bad solder joint that was my bad... When I...

Ok I think I found a bad solder joint.. Fixed that all up and shes sounding good again...

Wish everything was that easy. Now I gotta figure out some way of covering up that other large coil as I think that was what caused the issue in the first place.

Any suggestions?

Thanks again,
James

Ok So I got the New Fets in.. The AMP is no longer blowing fuses but going into protection mode now. Any suggestions?

The Fets were replaced and that was all that was done.


Thanks again,
James

Thanks.. avnet will work great. I found a source for another brand with simular specs however it should provide a little better performance. Fairchild p/n FQA30N40 I have some samples of the fairchild on the way that should be here tomorrow. Has anyone used these as replacements before? Any concerns...

If the current is shooting up my guess would be a dead short somewhere... PG made a change a while back to the amp that placed a piece of brown cardboard type tape to the top have of the case. Is this there? Also how do the caps look. Any of them look like they are swollen on the tops?


James

I need to find a cheaper place to pick up roughly 8 output fets P/n IRFP360LC

Anyone know of any leads on getting these.

Thanks again,
James

Well That seems kind of strange... I under advice of The Tech Support person pulled the unit apart to check for cracked solder, buldging caps, anything burnt or obvious failures as well as check the Fan function and making sure it was plugged in... Everything seemed to check out fine... Well not to ...

Thanks for the offer.. Its gotta be for a 95 civic w/o AC which seem to be few and far between... I might call a few shops and see if I cant get a rebuild kit and just mod mine into a HO...

James

Well I talked to PG today and we definetly think the amp is overheating... I can drive for about 30mins and everything is fine then it starts to go into protection mode... We checked the fan and that was working good atleast powered by a seperate source. Checked for bulging caps and those all looked...

i plan to call pg and see if i can open it up and visually inspect for cracked solder joints ect without voiding my warranty as i am IPC certified in pcba rework and repair but i dont know if that would be an option or not...

well about to the end of my 30min drive to work it did it again. I am thinking it has to be an amp problem as its fine for a little while. but to please pg i will take apart the polks and verify its not polks wire job

My Fluke is a true RMS so it shouldnt matter.


James

Well I just went thru the System again.. Set the gain to 69.2v using a 50hz test tone... with my deck farther than I would ever turn it up... I am not tearing apart my speakers and I highly doubt that is the case...

Will try again in the morning on my way to work.


James

Well I spoke too soon.. Happened again... Called Tech and they were pretty much no help... Said it must be the Speakers causing the issue. Kinda funny as they V8001 came off yesterday working perfectly and the 1200.1 when it using all the same wire except the Additional Power and ground wire that wa...

Well I think I am good now... Seems it is not shutting off any longer and seems to work pretty damn good. What a stepup from the V8001. I have the Amp running ~ 40v right now as I am not home to raise the Voltage any more. Will do that tonight and report back. But so far where its at with the speake...

Mine is a Xenon 1200.1

I will try bridging the outputs and see if that helps... I turned down the Gain some so hopefully bridging it will fix the issue...

If not I will Give PG a call later today when they open.



James

I just picked up a 1200.1 from the F&F sale and got it all hooked up today to replace my 8001. I set the Gain correctly using a Fluke DMM to 49.3v which should give me the 1200 rms that I am looking for. Subsonic is 14 ish clicks for around freq cutoff around 20 ish if I remember correctly. Bass...
