In the pyramid post you hear a lot of stories about being unsuccesful in smoking an amp. How about some stories about those who have been succesful(intentional or not)in destroying amps. Every onece in a while someone metions something about one of the rockford a2 amps smoking id like to hear the circumstances.

Over the summer I put 4 15s on a power acoustik 2200. I used the same amp for over a year on 2 15s without any problems. needless to say the amp didn't like all 4 speakers and the smoke rolled out of the amp, and that was my only amp for personal use.

I've got a Power 650 that I used in my old Beretta... Back in summer of 92-93' I was cruising around this place called Shawnee Mission Park where all the hot chicks grow and I was having a great time with some friends of mine until my sub stopped working. I sobered up immediately thinking my amp or sub (an old SPP-124 RF) was toast, so we left to find out what happened. I go home to check things... so I first check the in-line speaker fuses, they were ok so stupid me thinks the internal board fuses had popped. I pull the amp off the mount and take off the back cover.(?) Anyway, it's hard to see if the little bastards were intact so I get some needle pliers, wrap the tips in elec. tape and pull each one out. Needless to say my grip on one slipped and a fuse dropped onto the board where it proceeded to discharge all the internal caps and fry all right-channel MOSFET's.($300) Turned out to be a blown sub. At least the new sub was free. Damn MOSFET's.

Sure have, took an old Jensen amp that my friend had lying around and tried to have a little fun. Ran it parallel into my JL 15W4 dual 2 ohm sub. Played it for quite some time and it suddenly quit, I looked in the trunk and smoke was pooring out the poor s.o.b., I never laughed harder in my life.

I bought a "demo" Clarion 920EQ for about 100 dollars less than usual. I hooked it up and listened to it all day. Turned the stereo on that night to show a friend and BLAM! Smoke was pouring out of my EQ brain in the glovebox. The two main input rca terminals came off with the rca cords when I tried to get it out. I don't know why I put this story in "humerous stories" it actually made me cry.

i also had a jensen amp.i had it running 2 10's and a 12(amp running at 1.33 ohms).it got pretty hot to the touch but it would run hard all day long and never shut down or smoked.

When I got my Z28 at 19 I dropped my Alpine 6x9s in off a LearJet 65x2 while I was building the box. I'm cruizing with a buddy when the music quits. THe amp was almost glowing and smelled real bad. CHecked the Alps and they were frozen.
Alpine blamed the amp and wouldn't warranty the speakers.
LearJet blamed the speakers but fixed the amp.
Sales guy in our store was putting a RF 2300 on the board. Hooked up power first and then accidentally touched the ground to the heatsink. BANG! Mmmmmmm, blown caps...

Hrm, back to the S-10. Sherwood 25x2 amp and the LA Sound Malibu 120 (60x2). Evrything was clean until I introduced the Sherwood, then the whole system got noisy!!
Replaced the Sherwood with a RF Series 1 20x2 (little black grills) amp. Wrong fuse was in it, 10 instead of 15....Sizzle...Crack...POP!!! Dealer replaced for free . All was good then.

When MTX says there amps aren't 2 ohm mono stable don't try it! I had a 2300xw when the new ones first came out a couple years ago. And I threw a old 15" 2 omh MTX terminator sub in my car for kicks. I ended up fryning the amp after a half hour, the emblen on the front of the amp melted onto the nice white paint. MTX says the power supply was fried they fixed it under warranty. Still have the Terminator somewhere.

I've killed one amp so far, and that was a Jensen. When I first started getting into car audio, my first amp was a Jensen (50x4, probably really did 15x4 or something). Anyway, I was washin' my baby, and I guess the seal on my trunk isn't all that great and some water got on my Jensen. When I turned on my car, I didn't have any stereo. I was like, WTF?! So I walk back and there my Jensen is, smoking and water all over it.
I still haven't killed my RF 800a2 though. I've been runnin' her at 1ohm mono, and she has yet to cut out on me. I don't see why people say they don't make RF's like they used to...

I had a PPI ProMos 50 in a friends comp car. I had just finished a pretty kewl install in it (an 87 GN), and he was using my amp till he got his MTX Terminator (remember those, the PPI built red ones?). Anyway, we had a motorized amp rack that showed off the board, well, to facilitate this, I removed the bottom plate of my ProMos, instead of cutting a hole in it. Didn't realize that the outputs depend on that piece of metal to hold them to the sink. Ran for about 5 minutes at low volume while I cleaned up a little. Jumped in to see how she played, paused CD, cranked volume, un-pause... boom boom silence. PPI did fix it for me though, hats off to Bart Deal, who was with Phaze last time we spoke. Worst part? Regionals in Indianapolis were 2 days away. Fed-ex'd both ways, had it about 3 hours before we left for Indy.... Placed 4th after about 10 minutes of good tuning time.

I've had my initial share of shorted outputs when I started out. But the best memory of intentionally smoking an amplifier has to go way back to when I worked at a service shop, and a customer traded in his "Ampzilla" power amplifier(home audio), our technicien decided to "take it to the limit", the resuting smoke show, was facinating but the smell kicked us out of there for two hours, and remained for 3 days.

I had a installer put a kicker 352xi in a truck on pair of 8ohm JL Audio 10w0. He was a new installer so we made him have some one check everything out before he tried it out. So I checked it out and every thing was cool so i had him try it out and pull it around front. As he was pulling around me and one of the sales guys were out front talking and noticed smoke rolling out of the windows as he pulled up. He hoped out and imdiatley pulled the fuse and started flipping out cause it was glowing red under the seat. After the smoke cleared i got in there and start to see what was going on. Every thing was still fine so i pulled the amp put a new one in ran it for a while no problems checked the bad one all that you could make out on the inside was a couple of caps and resistors that didnt melt yet the rest was on glob of plastic. Belive it or not Kicker warrentyed it and said it must a been a def. equiptment.

my techs at work call that the I D 10 T problem
heh..... is speech, it sounds harmless enough, but write it down, and it becomes IDIOT
customer comes up with a blown rockford 100a2, we ask what hes running on it, he replies, 2 orion XTR 12 4 ohms, we ask if he bridged it, he says yes, we yell across the bench, john, its an I D 10 T problem this time.. he looks back, laugs, we replace the amp and tell customer its his only I D 10 T exchange... heheh

I (back in the day when I knew nothing about car stereo), helped a friend of mine with an 89 dodge shadow wire his stereo. He had new 4 inches, a tape deck and a 40 watt power booster all SPARKOMATIC. He also had found some 10 inch realistic home speakers. Needless to say, we through the 10s in the hatch, wired the factory speakers in and put the 4s under the seat. All into that little power booster in 1 ohm mono per channel. It got really hot and kept burning up fuses, but it didn't blow, distortion was a little high (around 2%), finally it just died, it got so hot that it melted the inside of his dash (it was mounted in the ashtray) and shorted out the connection. Lot of stereo for only $35.

Well, here's one for you all. I had a Jensen amp, a couple years ago, my first amp. It was rated at 75x4, I think, but I had it bridged to 200x2. So anyways, I ran it like this for quite a while until I got something better, then I sold it to a buddy. I hooked it up to a couple of kicker 12s in his camaro, and all was well. Then he bought like 4 15s off somebody, and decides he can just wire up all 4 of them the same way the 2 12s were wired. He has a camaro, and got a piece of plywood that kinda fit in the well. He mounted 2 kicker comp 15s to the plywood, and put the other 2 15s in the corners of his hatch, with no baffle, nothing. The 15s were one RF series 1, one old style kicker with yellow KICKER lettering, and the 2 comps. Anyways, his power wire it 20 guage speaker wire running from the fuse box. Needless to say, he comes to my house, smoke pouring out the windows, and I hook up some 10 guage and disconnect the extra 2 15s. That amp finally died after he sold it to another friend, this one ran the RF series 1 and the old kicker off it, but he spliced into a couple of RCA cables and connected the inside wires to his rear speakers, at the speakers. It was funny, you could slap the rear fender and make the subs hum. Well, that's my novel.

Well here is a few amps all blown in the testing and screwing around with the truck our team is doing. Orion 2100hcca. Running at 1 ohm mono with the voltage on the truck droping to under 9.0 volts. Hcca 2100 was returned and never seen again.
Autotek AMX200.2's one blew at USAC finals cause someone sabatoged the RCA's to the amp. Then the other 2 AMX 200.2's at usac finals cause of a short in the podum. The 3 AMX 200.2 were fixed by Autotek no question asked. We got the 3 back and in testing again blew one of the 3 cause of low voltage again and runing it lower then factory rated.
We got the voltage problem fixed and are amp other AMX200.2 is kicking some arse.

A couple years back, when RF released the new batch of Power series amps, my brother decided he wanted one. So, we got him a 50x2, figuring we could use it for just about anything. So, when I was looking at all the little features, it mentioned being able to handle low impedences, and it had thermal overload protection. We decided that since it was new, we could vaporize it to see how low an impedence it could handle, and if the thermal protection was as good as the guys at the shop said. I started with one sub, then added another, then two more, then four MORE. The amp was a bit warm, but at full volume, it just kept going. So then I pulled out my Veritas Accumatch, and started over. We eventually reached 3/16 ohm load, and the amp played full-tilt(4v head, gains at minimum=FULL OUTPUT) for seven minutes, after which it thermaled out, and we had to let it rest, because I was able to melt plastic on the heatsink, but it NEVER hurt the amp. I put a pair of fans on it, and then it could go for about 20 minutes before overheating. But I couldn't kill the thing through abusive install work. Now, if I ran jumper cables from my battery bank to the RCAs...

Yep. We had a 50m on 24 8 ohm 10s all parallel in our sound room. No sweat. When we sold the 50m we dropped a 50m2 on it, bridged. Again no sweat.
