How can I wire a 2 ohm and 4 ohm kicker dual voice coil speakers to a JL 500 1 channel amp


Ok, so you have a single 2 ohm speaker and a 4 ohm speaker with dual voice coils? The JBL Is a 2 Ohm load I believe.


I ran through the maths...

Series parallel with the 4 Ohms in series in parallel with the 2 Ohm gives you 1.6 Ohms

2 x 4 ohms in parallel with a 2 ohm in series gives you 4 Ohms which is no good.

All three in series give you 10 ohms which is no good.

All three parallel gives 1 ohm.

So with this set up you cannot create a perfect match. So you will always run the risk of bad audio or the amp blowing at high output.

Kicker impulse 325xi 2 channel


have this amp, had this problem, had to crack it open to re-solder the RCA input jack as the soldered mount connections failed. Seems like the issue was the input spiking when those connections moved around, or it was caused by poor connection between the mosfets and heat-sink(causing near-instant overheat condition). There are 4 or 6, don't remember. They were attached to 2 slide rail looking pieces of aluminum that fit in the shell. I broke them free (as it made the job faster) and reattached with minimal heat-sink compound. Thing runs like a champ now. Get another 20 years out of it.

Heard a pop, tv went off, and it won't power up


Power supply in most cases and a lot of the time the part is under a heat sink where you cannot see it.

You might have more help if you posted the question again with the exact brand and model number.......

I have an R4000 that seems to turn itself off whenever it chooses to. The fan speeds up and of course seconds later, I either have a blue screen or it is just off. I cannot afford a new computer as I am in...


When Compaq r4000 Too heat >> fan speedup to cool the processor temperature down.
Mostly old laptop has the same problem > over heat
1.Locate your Heat sink Beside/below the unit..try clean it as u can,specially the fan it self,something might interupt the fan speed eg.hair fall, dust.
2.Power ON and quickly press F8 >>> it will show some text line >> choose safe mode >>> enter >>> enter
3.On safe mode youll see a black screen desktop with safe mode marker on every angle.
4.if there any restore mode pops out choose it to reverse your system to the date earlier eg.1 month ago
5.restart >>>

The fan on my CE1000 does not come on when the amp is powered up. The amp seems to be playing normally, but I am afraid I may over heat the amp if the fan is not working. Is this normal?


The Thermal Senser on the Heat sink may be Defective. Heat the Thermal senser and see if Fan Turns on. It is a device with 2 screws holding it to the heat sink

Technics SU-G95 Amplifier, Intermittent popping/crackling noise


The heat sink has the power modules attached but also has 2 power transistors that become disconnected from the circuit board when the heat sink moves or flexes. The pins on each need to be resoldered (it helps to bend them a bit too, prior to soldering). Had the same problem on the same amp today and that was the fix. There was no sound other than a clicking when the volume control was rotated.

Popping and fading of sound


The "popping" sound could be electricity jumping from one place to another.An internal SHORT in a transistor, an internal OPEN in a resistor.Intermittent [sometimes it does,sometimes it dose not] arcing electronic parts.
Dust [metal filings,very fine hair that burns like a fuse] & dirt [anything metal], arcing (shorted) capacitors.Bad connections on ANY ground connector.
Possible:: your surround sound MASKED the popping sounds by acting like a FILTER.Which lets me to think that your problem is in the audio section.

DENON AMP OVERHEATED


More than likely, you popped an amp channel. My experience is that it is the one closest to the middle of the heat sink.

Take it to an authorized service center, and be prepared for a large bill. Good luck...Rob
