hey all. i need some amp help

[GrandmasterCow]

hey. i have a pyramid pb880,1200watt amp, and suddenly it shut off while i was on my way home the other day. i checked wiring, its all find. when i disconnect ground, the yellow and red lights on the amp turn on, when i connect it back, it sparks and all lights on amp shut off. no matter what im gettting no sound from the subs. nothings vhanged from before it stopped working, and all the fuses are working and all cables are intact. im completely lost...??

This is very strange. Try unhooking all your speaker wires coming from the amp and see what happens. It is possible that you have a short iside the box. Dunno for sure, just an idea. Also make sure none of you power or ground feeds are arcing over to any of the other terminals. Maybe something internal in the amp is causing the problem? Afterall, didn't you say it's a pyramid?

[v6maro]

ok #1 it's a pyramid
#2, they suck ***
#3 you fried the internal fuse

always always always dissconnect the power from the battery when doing this, for this exact reason.

oh yeah, the two ligts you saw were the power and an Ohm light, before it fried.

so wait. is there anything i can do to get it workin again? i removed all speaker wires to it and it still does it. also, my turn signal stopped working around same time my amp stopped working. the turn sig. on the left side, while amp is on the right...

[megabass]

Hold on here. Do you even have voltage from your turn-on wire? Strange about the turn signal. Hope you don't have them tied together somehow unless it's just a coincidence. Check your fuses. Even if you did fry the amp, no big loss IMO. You can get a lot better amp used off ebay.

HEY did you check your remote wire comming from your radio this wire cuts the amp on and off.
it could have got disconected or shorted some how

[GrandmasterCow]

yea the remote is fine. all wiring so far is fine. the turn sig just stopped working, no, they're not connected or anything. its really off. one minute working, next stopped. if i have to get new one, anyone recommend and good ones? i got 2 10inch 800watt audiobahn subs and 2 10in 500watt jbl's

[GrandmasterCow]

still aint workin =\. i jsut checked all wiring again and did some stuff some friends told me too, but it still didnt work. does anyone got any ideas at all? heh. anyway to test it? cause it seems like its not accepting ground connected heh. when i disconnect ground, protect and power lights come on. but when i connect ground, they go off. they only on when no ground connected, and remote on. even when ground and positive, audio cables and speakers all unconnected and only thing connected is remote, the two lights still light. i dont get it =\ heh

update:
well i shook the amp and it ratled so i oopened it up and saw that a resistor blew up, and the raddlting was the aluminum casing peices. i have to get another resistor and solder it in and it should work hopefully

[GrandmasterCow]

anyone got ideas?

[GrandmasterCow]

ok welp seems like its totally fuc*ed to hell today. i got 2 new fuse's for my amp at radioshack today, cause the two on it where blown, and it caught fire when i hooked up the positive!

[99firebirdconv.]

its the fuse or capacitor inside the amp. If you have a reciept take it back if they will warranty it, but yes Pyramid sucks, thats why this has happened. I had an old amp that did the same thing as you posted in your first post, the problem is internally. ;)

[GrandmasterCow]

yea, that's a lil prob: i purchased online with 2 year warrenty in june, but i got nothing to prove i bought it. no email cause aol deletes your emails, and my parents threw out the box for some odd reason...
