    I don't know what a driver IC looks like or what the power transisters look like are they the two small ones by the LEDs or is it the same size as the ones I blow up

If the power supply transistors blew out, it's possible that the output transistors have failed (shorted).

If you're going to try to repair it, there are likely 2 blown driver transistors near the driver IC (TL494). You must check them. If they're blown, the new 3205s will blow out again.

Keep blowing amps and high voltage output voltage please help


If your amp keeps blowing then you need to check your speaker set up, as its very possible that you have a blown speaker somewhere, or a couple of wires shorting together and that is causing the amp to overload... also check the ohm's of your speaker set up, remembering that:

Two 4 ohm speakers wired in parallel = 2 ohm whilst
Two 4 ohm speakers wired in series = 8 ohms

Car amps are rated at 4 ohms and failure to match speakers to this can cause amps to run very hot or blow.

I just replaced an amp and now the inline fuse by the battery keeps blowing


Most likely you have your power and ground connections reversed on the amp. That will cause the fuse to blow immediately upon contacting the two sides of the fuse. If the fuse stays intact for a short while but pops after turning the amp/car on and your connections are correct then there's a problem with the amplifier and it either needs to be serviced or replaced.

Pyle PLA885 amplifier blows 25amp fuse. Ideas?


signs of a short, did any wires touch while you where hooking or un hooking the amp? if not then the internal power supply probably has a short in it and needs to be repaired. you can swap the fuse for a good one and hook it back up and make sure you don't touch any wires and if it blows it again then your issues is internal and will need repair if it doesn't and everything seems fine then wires could have touched or the amp was ran past it's limit and blew the fuse to protect it self. good luck and ask any more question you have

Fuse blew on on cable coming from batter, replaced fuse now my kenwood excelon ddx7015 and amp xxv-02a wont power up , but when i test the fuses they have power


What size fuse are you using? You need a 30-
amp at least and #8 to #10 wire I would go
with the # 8 maybe lower, if it blows a fuwse
now you have a shorted output in your amp.
May This Will Help.

Amp grounding out


If the amp is blowing fuses, you could have one of several problems. The only one of those problems you could fix yourself is if you have a shorted speaker. A speaker that is shorted in the voice coil can cause the fuse to blow. To check if this is causing it, dis-connect the speakers and then turn it back on. If no fuse blows there is a good chance that a speaker is shorted, take the speakers to somebody or someplace that can check them properly. If the fuse still blows with no speakers connected, you have an internal problem in the amplifier.

If the fuse blows before you even turn the amp on, you have some shorted components in the power supply. If the fuse blows after the amp gets turned on, you have some shorted components in one or both of the output channels.

Unless you have some experience with electronics and have the proper tools to troubleshoot electronics, there is really nothing you can do yourself to fix the amp if it has internal problems.

You should take it to a repair center and get an estimate for repairing it, that way you can decide if the cost of the repair is worth the price of the repair. Sometimes it is better to just buy a new amp, but you first need to know what it will cost for repairing it. There is no way to tell you how much it will cost to repair without having the amplifier in front of me and troubleshooting it to see exactly what is wrong.

If I can be more help let me know, I have been repairing car and home audio equipment for almost 18 years and can offer you good honest advice.

Good luck,

Dave

Keep Blowing Fuses


Sounds like the amp is shorting somehow. You are obviously shorting out somewhere between the battery and the amp. Are you sure you grounding location is a good one? is the fuse blowing only when you turn the stereo on? Something is not hooked up correctly.

If the fuse at the battery is blowing then it's a short.

If the fuse on the amp is blowing then its probably a bad amp.

Amps


If the amp blows a fuse with no remote voltage applied, the amp has a short in the primary side of the power supply. If the fuse only blows after remote voltage is applied, the amp probably has shorted output transistors.

Amp blowing fuses


The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).
