Does Anyone Know What's Wrong With My Amplifier?

Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 35 Registered: Jun-06 | This thread is a newer thread to my amplifier problem. To view what's already been said, click on the link... https://www.ecoustics.com/electronics/forum/car-audio/241083.html This morning when I went out to fix my friends brakes, I noticed that my amplifier was ON and WORKING! After letting it play for about 5 min, I turned the volume up alittle and still played ok, so I turned it up alittle (and when I say alittle I mean by like, 1 or 2) and it turned right off on me again. Like before, I checked all the wires and fuses and they were all still ok and also, there was no red light on when my amplifier turned off. Like before it wasn't hot either, it was still pretty cold. Does anyone know what could be wrong with my amplifier? |

If it does, then your gain/level is not set correctly, or you could have a low ohm resistance on the speaker terminals. |

Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 38 Registered: Jun-06 | no, it's a Pioneer TS-W301R. The amplifier (MTX Audio Thunder 4122) I got off ebay a long while ago refubrished from MTX. Do you guys think that maybe it wasn't fixed correctly? |

Silver Member Username: Troy81Tavernier, Fl Us Post Number: 420 Registered: Mar-06 | no but i was serious, it could very well be one of the voice coils burnt and the other one plays until the cone starts twisting whats your voice coil config, does it go to about 2/3 volume then shut off, cuz an amp will run at too low an imepdence and wont shut off untill it trys to pust out too much power, did you ever get a smell coming from you subs? also, has it ever worked before? |

Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 39 Registered: Jun-06 | "yup, if it ever worked before with the same setup then im willing to bet you meltedt part of your voice coil... audiobahns?" Are you talking about the subwoofer or the amplifier? And if it's the subwoofer, then how can it turn off my amplifier? The subwoofer is brand new and I don't push anything to hard. For my volume controls, my head unit goes up to somewhere around 50-60 and I always keep my volume at 25. Also on my head unit, I have my Lows set at +3 (out of +6). My gain on my amplifier is set at around 1/3. |

Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 40 Registered: Jun-06 | No...there has never been any sort of burning smell or any type of smell comming from the subwoofer. Yes!...My system worked for about a week before this started happening. The gain, volume, and everything else has always been the same, I haven't changed anything since ive had everything hooked up. |

Silver Member Username: Troy81Tavernier, Fl Us Post Number: 424 Registered: Mar-06 | well if you melted part of your voice coils that would drastically lower your impedance hence turning off your amp, im just throwing ideas, sorry if im offending you, it could be that the amp is blown |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 44 Registered: Jun-06 | Well I was planning on getting an amplifier to replace it anyways and use this one on my 6x9's but, it seems like I won't be able to... No, im not offended and thanks for throwing some ideas out here at me. Better having some ideas than being confused on what's going on... How would I check to see if the voice coils are melted? What would be some signs or things to look for? (Ya, sounds stupid but, ive never seen what a melted voice coil looks like...) If the amplifier was blown, then why would it turn back on? If it's dead it should stay dead! |

Silver Member Username: Troy81Tavernier, Fl Us Post Number: 425 Registered: Mar-06 | to tell you the truth ive seen melted voice coils and i dont know what they look like, the only thing i noticed was the soldier from the wire was all over the inside of the cone |
|
Silver Member Username: JohnfiacIl USA Post Number: 202 Registered: Mar-06 | Hahaha troy i like that one, "It must be audiobahn" my voice coil was on fire, the carboard under it was burned up as soon as i turned it on...i bought it on ebay, he said it was never used and it looked factory sealed still.... i never got it fixed or money back for it  big waste... To check if the coils are melted you need to remove the cover... YOur would see some copper wires wounded around a ring ussualy from 2-4inchs round... look very closesy around them for wires that are burned(somtimes looks like they are cut when they come apart after melting) also check your power connections on the inside of the amp....from your terminals to the motherboard oft he amp. |
|
Silver Member Username: JohnfiacIl USA Post Number: 203 Registered: Mar-06 | It sorta sounds like it is a loose power connection on the inside of the amp if everything else is fine.... maybe your hit a bump or give it to much bass and it moves... I had a jensen that the soldier on the positive terminal was broke and it wigled on and off all the time. that might be it right there. |

Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 50 Registered: Jun-06 | Hm...i'll have to check that out, the amp was refurbrished so maybe that's what was wrong with it in the first place? Well, now that im out of school I have plenty of time to operate on this amp. Tomarrow i'll have to open her up and see what's going on inside there! Sorry if this was answered above, but how would the voice coils melt? Because like, their RMS is only 150 and im giving it 200. Is 50 more watts too much for this woofer? If the problem is the woofer, im glad I have a 1 year warranty from sonicelectronix! (NOTE TO SELF: TS-W301R's ARN'T GOOD IF THIS WOOFER IS BROKE! DO NOT BUY ANOTHER 1 AS PLANNED -_-) |
|
Silver Member Username: JohnfiacIl USA Post Number: 205 Registered: Mar-06 | depending on brands and all you can over power some woofers, but the woofer would have anything to do with the amp not turning on, if it was the woofer it might put the amp into protection or somthing but i dont think it should ever turn it off. |
|
Silver Member Username: Troy81Tavernier, Fl Us Post Number: 428 Registered: Mar-06 | well my audiobahns were sposed to take 1100rms but i melted them with 575 |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 52 Registered: Jun-06 | Ok, well I didn't want to unscrew everything to take a look at my Pioneer so I switched it with a 10" MA to see if it would work. But, since it didn't, then that means that my Pioneer is still ok and theres something wrong with my amplifier. Im about to take it apart right now to see if something wrong. This is the first time I opened up an amplifier, are there any main things I should be looking for? |

Silver Member Username: _jay_Post Number: 159 Registered: Mar-06 | ...did you check to make sure you had good ground? |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 54 Registered: Jun-06 | I opened my amp up, but nothing seems to be out of the ordinary. Nothing is melted or loose. There are a couple things in here that I don't know about though. Like, there are a couple marks in here and by marks I mean like someone took a perm marker and colored a couple places. Also, there was a green piece of tape on some grey square thing (don't know what it is but, it's labeled 105J63) |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 55 Registered: Jun-06 | Yes, the amplifier was working for 3 days with out any problems before this started happening. |
|
Silver Member Username: Troy81Tavernier, Fl Us Post Number: 432 Registered: Mar-06 | im sorry but i know about as much as i know about aliens about insides of amps, sorry, good call on checking your voice coils though, good idea, also like it was said before, do you have a good ground?, if theres paint on the metal, sand it off and try it then |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 57 Registered: Jun-06 | Well, if the ground was bad from when I first installed it, why would it work for a couple days then just...not work anymore? I don't know, but, sometime im gonna barrow a voltmeter from a friend and see if maybe something isn't getting power anymore. Originaly, I hooked up my negative to the latch on my trunk, well, not trunk, but like, back door I guess (SUV...). Also today place the negative in different places around my SUV to see if it was that, but, I got nothing from like 5 different places. CURSE MY AMP! |

Silver Member Username: Troy81Tavernier, Fl Us Post Number: 434 Registered: Mar-06 | we'll get to the bottom of this, when it turns off how long does it stay off for? did your lights dim alot when it did work? cuz it could be starving for power.. is it going into protection or just turning off? that could be an ohm issue.. def need to check your ohms asap if anything smash the amp with a hammer then try it haha jk dont do that |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 59 Registered: Jun-06 | lol, maybe I will if I have to replace it... When my amp turns off, it will stay off until the next day...strange isn't it? No, my head lights do not dim when it was working. The amplifier is not going into protection, it just...turns off... How would I check my Ohms??? I contacted a member of MTX and they don't even know what's wrong with it. They said if I figure it out "Please let us know what it was" (that was their quote...) |
|
Silver Member Username: JohnfiacIl USA Post Number: 226 Registered: Mar-06 | a multimeter ..... what subs do u have\model? |
|
Silver Member Username: Troy81Tavernier, Fl Us Post Number: 436 Registered: Mar-06 | how much trouble would it be to rewire your remote? it might have a bad connection, but as you can tell im running out of ideas sorry, if i think of anything else ill definately get back to you |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 62 Registered: Jun-06 | Today when I went to get take my final (last test before I graduate ) It started working again and when I left to go home it was still working. I turned the volume up a bit to see if it would turn off and it didnt! So im not really sure what's going on with my amplifier but, I will probably be replacing with a Audiobahn A2002T so im not gonna keep screwing around with this amplifier to know why it's doing what it's doing. Probably end up putting it on ebay for $1 and see how high the price will go for it. Thanks to everyone that gave me ideas, suggestions and answered my questions! Unlike MTX......... |

Silver Member Username: Troy81Tavernier, Fl Us Post Number: 437 Registered: Mar-06 | uhhh, im sorry i helped you, a non working amp is better than audiobahn, if i were you i would make bass with your mouth instead of buying an audiobahn, audiobahn is like donating to charity |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 71 Registered: Jun-06 | Well then, what amp would you preffer to get that will power 2 Pioneer TS-W301R's nicely? |
|
Silver Member Username: Troy81Tavernier, Fl Us Post Number: 438 Registered: Mar-06 | whats your budget? |
|
Silver Member Username: Troy81Tavernier, Fl Us Post Number: 439 Registered: Mar-06 | that, and what r your voice coils? |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 76 Registered: Jun-06 | Single voice coil, 4 Ohms on each sub, im willing to spend around $200 on an amp for my subs |
|
Bronze Member Username: KaerfplSpencerport, NY USA Post Number: 77 Registered: Jun-06 | Here is a thred I made with some different amps that would work with what I have. Any of them ok? https://www.ecoustics.com/electronics/forum/car-audio/242021.html |
|
Silver Member Username: Troy81Tavernier, Fl Us Post Number: 442 Registered: Mar-06 | i would pick a kicker mono block that is 300- 400 watts at 4 ohms, but if you want to spend some money on an awsome amp, get a JL that is 300-400 at 1-4 ohms, that would be the best |
