Internal capacitors keep burning

Had the amp approx. 1year from new, recently about 2weeks ago, internal capacitors burned but amp was still working, replaced capacitors but it occurred again. Want to know what other components i should check for damage and cause.

Youre overloading the output reduce to at least 4 ohms impedence speakers

Does the jl audio 250/1 have any internal fusing that would affect output . my buddy hooked up booster cables backwards and it did blow main fuse at battery but now lights are on and noboby is home.


I have seen circuit traces litterally burn up from reverse polarity. Also the capacitors on the 12 volt main line can smoke and causing the DC/DC circuit not to function. Traces can be repaired with the proper sized copper tape and capacitors are cheap. The only way to be sure is to open the unit up, look for strange liquids and evidence of burn or fire.

My amp started to smoke, and cut off,had a real loud burning smell,has not worked since.


Sounds like it was playing? If it was your voltage dropped and the mosfet power supply got toasted. These amps are notorius for burning up at low voltage. Kicker did not put a low voltage shut off on it.,

So i hooked up the amp useing the pre-existing 8 gauge wire with a 30 amp fuse it worked for about and hour and started blowing the 30 amp line fuse. i replaced the line from 8 to 4 gauge and installed an...


this sound like a case of arcing power wire it happens very very easy if u use cheap wire especially from walmart. whatever u do keep using fuses and get a batt test asap. if u take out the fuses ull burn the amp like no other and plobably burn out the power rails which will be cheaper to buy a new amp after that

Why does my mtx 6001 amp keep cutting out, it has worked fine for 7 years now


something is starting to fault out, either is internal, with like the thermal protection failing, or its external like the voice coils of the subs slowly burning up, changing the impendence. or it could be something simple like a ground wire or positive wire working loose from all the years of vibration.

My transistor keep burning wat can be wrong


You may be overloading the amp with too much subs or to low of a ohms load that it can handle and setting it to maximium setting.

Possibility is also it is poorly soldered internally and a solder bead has short circuited the circuit board. So no matter how many times you replace the fuse it blows. Or a small metal object got inside and caused it too short too!! Send it back to Manufacturer if you got warranty or else open it up yourself and investigate the problem see if you a burned tracer and reconnect it or a burned component like a resister or capacitor and replace it with the same value at Radio Shack. You may have to learn how to solder, desolder using a pencil soldering tool. The Soldering gun is too strong and may damage it further unless your very skilled at it.

Burned up


You can try opening it up check the circuit board and see what capacitor burned up or other resistors, transistors got burned and go to Radio Shack and solder the new one to replace the burned one. Or if you still have the reciept return it to the manufactorer and hope it has a 1 year Extended service protection on it so they can replace it.

Amp worked shortly, now no power


It sounds like you clipped the amp and did damage to It and possibly the speakers. I would check all connections and wires first. If you used too light of wire you may have either burnt the insulation off or burned through the wire. High power amps need large power cables. If thats all ok, did you have a fuse from the pos power terminal? Check that. If every fuse is good and the connection are good then it sounds like you may have blown an internal component in the amp such as a Transistor, Diode, or Capacitor. This would mean taking it to a service facility.

Sony xm


internal heat capacitor or even a bad connection indside amp is bad giving you a hi output load wich the amp has an auto matic sensor to send it into this offset you speak of so it does not burn up
