The fans might not be running and if the fans are running then you need to keep the amp cool by letting it have access to the a/c or air from the windows. think of it like if you keep your body in a box for a long period of time and there is no air circulating then your body heats up same thing an amp need air circulating to stay cool.

It keep over heating


How does it keep overheating ?

The first time the temp gauge goes over
215 or 220 you shut it off & get out

You then have it towed or drive a short distance
to a shop & have it fixed --unless you intend to ruin it

My jeep is overheating when stop i change the fan relay head gasket put new radiator and keep overheating when i stop in the lights


It's easy to overlook but a bad clutch fan will cause overheating in stop & go traffic, while you're idling or out on the trail at low speeds. When you rev the motor, you should be able to hear the clutch fan 'roar' up to speed slightly behind your engine speed. It's a noticeable sound when it's fixed, but ya don't pay any attention to it if it has slowly gone bad... other than wondering why you're overheating.
CHEAP "FIX" #1: If your clutch fan is known to be bad, you can remove it and drill two small holes in it where the internal spring is located and put two sheet metal screws in to make it 'lock up' all the time. Put these 180* apart, directly across from one another to keep things balanced. Upside: .20 cents to fix. Downside: Reduced gas milage with it going all the time.
CLUTCH FAN REPLACEMENT UPGRADE: Pull out the clutch fan and use it to enhance your garage wall. Instead of putting in another clutch fan, you can free up some horsepower when you install another electric fan for primary cooling

My acer aspire 5315 shuts off suddenly and won't restart till it wants to. I replaced the battery, no difference....what's wrong?


This could be a sign that your laptop is overheating. If you touch the laptop while it is running & you find it too hot, make sure that the fan is running properly & that the air ways are not blocked.
You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced

If none of this solves the problem, or is not the case, then you might have a bad motherboard.

Overheating amp problem...easially fixed, i think....


depends on the sub rating.

if subs are 2 ohm rated you can ONLY get 1 or 4 ohms..
2x2=4ohm series
2/2=1ohm parallel

if subs are 4 ohm rated wire in parallel
4/2=2ohm

look it up google for diagram if you need one.

Amp overheating and adjusting gain and frequency


Overheating in amplifiers is often caused by a speaker load of too low impedance. If your L7 is a dual 4-ohm voice coil, and if you're using the amplifier in bridged mode, that may be causing your problem. Dual 4-ohm subs, with the voice coils wired in parallel, present a 2-ohm load to the amp. Your amp is capable of running a 2 ohm load in 2-channel mode, but not bridged mode. The best fix with your equipment would be to re-wire the sub's voice coils in series, resulting in an 8-ohm load. The amplifier's power output will drop sharply, but you won't have problems with overheating in that configuration. There's a good chance that you'll still be able to get all the volume you want, even with an 8-ohm setup; otherwise you'll probably want to switch to a mono amp designed for a 2-ohm load.
