    I have an Alpine CDE-9852 for my deck, a Solo Baric L512, and a crunch pzi 250.2 for my amp. I had it working fine for a couple months and it sounded wonderful. Then the lights started flickering when the bass hit. And after awhile the sub would just cut out once I turned my deck volume past 5 or so. I was persistant and tried making it stay on and it resulted in my amp smoking. I am still able to get the system to work, but my amp will always end up smoking after a few minutes. I have not the slightest clue what to do. Any advice?

    Does anyone have a circuit diagram for the MTX 4001 Amp?



    My amp blows its fuses as soon as energized. I've checked the output transistors and they are all fine. There is no sign of burnt components or odour from the circuit board.



    I'd like to check out the power supply circuitry, but I need the diagram, or some expert suggestions.



    Thanks

If you saw smoke something fried, im surprised it still kicks on at all. my best advice is if you kno how to use a soldering iron, see if you can locate the problem, (i.e. melted wires and such), if not best would be to look for a new amp. hope this helps

SOURCE: Amp won't turn on

disconnect audio inputs and outputs and see if one of those are causing it , if it still does it with all audio inputs and outputs disconnected then there is a problem with the power amp

SOURCE: I have checked all connections to my amp

Your amp could be in protection mode! Sometimes turning up to high or wires touching will put in protection mode! It will have to be unplugged for a day or two to drain all power out of the memory. Leave accessorie/ignition wire hooked up, just not power and ground wiring. It should reset itself.

Amp fuse 30a keep blowing


You have possibly melted a couple of wires together along the radio circuit. Also the radio unit itself has 1 or more protection fuses actually inside the unit that have blown, usually at back of unit in little bay near the wire clusters.
Check your relays too, a blow out through jump starting can do all sorts of little burn-outs.

Well it's temping to put in biggfer fuses as the problem gets worse but the size of the fuses are to keep you from burning things up so you've from your probem with a 30 amp smoke test. The raditor fan wire is melted somewhere in the wire harnes to the wire for the trck lock or even key on circirts. the likly place to look is inside the stering collum. It takes the skills of removing the steering whel and the lcok plate and even then thats does'nt have to be where the problem is. You need to look under the dash after you remove the covers and use you nose to smeel for the burnt wiring and open up any thing the smells like it's been hot and anything the appers melted together. once a harness is found melted you need to seragete all the wires in the loom but don't cut the wires justy seaparte them. once you think you've got then all pulled apart so no bear wires touch each other or any meal parts put in the correct size fuses and see if you can connect the battery with out a spark. if you can you may then start checking to see what works and what does'nt.. This all sounds like too much work or too hard to do then you'll need to pay someone theat knows alot about car wiring problems to do it for you. I'll been doing this kind of work for the last 20 years and a'm alawys finding new things that are fried and burnt up. We all charge by the hour to do this work so the most experieced mechanic that works on cars like yours will probly find and fix the problem the fastest. therefore they may charge more per hour but their likly to get it right quicker and it'll stay fixed after they fix it.. This is the most likly kind of work to go sour after it's fixed cause they might miss a circuit that you use and they did'nt try. and as soon as it burns again it's back to the drawing board and if big fuses are use the fire can take the whole car.

Many cars have the cooling fan on a thermostat or time delay, to allow it to run for a short period of time after the engine turns off, to cool the engine off. You may have just never noticed it before. So I wouldn't worry about that.
Your real problem is the blowing fuses, apparently you have a short somewhere in your wiring. Putting in bigger and bigger fuses is a great way to set fire to your wiring harness. It's possible that the wire is pinched or chafed somewhere, and perhaps when you hit a bump just right, it touches and shorts.
You may have to take this to the Chevy dealer or a GOOD independent shop to have them chase it down. Unless someone out there knows exactly what this is, it could be a tough one to find.

A/C smelled like smoke then blew 30A fuse - Silverado 1500 2004


You may want to change the blower motor as a precaution.
Do all the fan speeds work?
If not .....change the fan resistor board which is right beside the fan at the same time you change the blower fan motor.

Weather King blows fuse in Criterion II furnace


You probably have a shorted wire between the heater and the a/c. There are two wires that conncet the control power to the outdoor a/c from the heater they should be on terminal c & y in the heater. disconect those two wires and try it again if the fuse doesnt blow you have a short in the wire between the a/c & heater
