What else can I help you with?
If you replace a 4 ohm speaker with an 8 ohm speaker can the amplifier blow the speaker?
A1: The output impedance of a power amplifier is always less than 0.1 ohms. There are no 4 ohm amplifiers on the market! A2: I actually just bought a new car radio/CD player that specifically shows 4 ohm speakers on the sticker. It is designed to work optimally with 4 ohm speakers. If you use 8 ohm instead, it will work, but you will not get the full power output that is specified. The amp can only kick out so much voltage and so much amperage - if it is designed for 4 ohm speakers, and 200 watts (stereo, so 100 watts per speaker), it can supply 20 volts (P = V^2 / R). If you used 8 ohm speakers to this amplifier, each speaker would only get 50 watts powered at full output voltage. Alternatively, if it is designed for 8 ohm speakers and 100 watts per speaker, it can provide 40 volts. If you used 4 ohm speakers instead, each speaker could be given 200 watts at 40 volts, resulting in severe overheating and damage to the amplifier.
Should you replace all of the electrolytic capacitors in an amplifier that has some burned out and has not been used in more than 20 years?
just to be safe i would change them all. If one of the other caps breaks it could leak onto the board and fry it.
Can you hook a water drain pipe to a 3'' sewer pipe and it be safe?
If you are talking about a roof water drain pipe to sewer it is illegal. If you are talking about a sink drain pipe well that is where they all connect to so yea.
Can an ac amplifier amplify the DC signals?
An amplifier generally amplifies an AC waveform (such as sound), and is powered by a DC source. The majority of the power at the output is then coming from a DC source (the power supply in a power amplifier will convert the 50/60Hz AC power in to DC for the amplifier circuitry). So you can make the argument the above (question) is a true statement. But an amplifier wouldn't be used to convert from DC to AC power (in general).

How can I safely connect an 8 ohm amplifier head to a 16 ohm speaker cabinet?
To safely connect an 8 ohm amplifier head to a 16 ohm speaker cabinet, you can use a series connection method. Connect the positive terminal of the amplifier to the positive terminal of the speaker, and then connect the negative terminal of the speaker to the negative terminal of the amplifier. This will create a total impedance of 24 ohms, which is safe for both the amplifier and the speaker.
Is it safe to connect a 300W ampilifer to a 60W Speaker?
Without getting into the multitude of variables and keeping this as simple as possible, NO ...Simply connecting a 300 watt amp to a speaker (driver or cabinet) will do no harm, that is, until you make an attempt at raising the volume! A speaker rated at 60 watts means just that ...it can handle 60 watts. At low volumes, no harm will come to the speaker, driven more powerfully, harm may soon come to it.
Can you use speaker wire for power wire for an amp?
It is not recommended to use speaker wire for power wire for an amp. Speaker wire is not designed to handle the high current load required for powering an amplifier. It is best to use appropriate gauge power wire to ensure safety and optimal performance of your amplifier.

Can you run speakers with an amplifier that has a bigger rms rating than the speakers rms rating For example run an 80 watt rms speakers with a 120 watt rms amplifier?
Yes you can. Contrary to popular belief, an amplifier rated with a higher output than the speaker rating rarely damage the speakers. If the amplifier overdrives the speakers, the sound quality will be dramatically affected. Most listeners will turn the level down to reduce the distortion being heard. The amplifier's power rating is the maximum power that it can produce and it does not mean the output power will be at that level. On the other hand, an amplifier that is overloaded will deliver distorted signals to the speakers. At high power levels, the distortion can be damaging to the speakers in a way that simply over driving a speaker is not. Therefore, it is as safe to use an overpowered amplifier with speakers as it is an amplifier that is rated at the same power or even lower power than the speakers.
Can 8 ohm speakers be used 4 ohm surround sound system?
It physically can but that is like putting the wrong amount of water through the wrong size pipe. It will work for awhile but something is going to give. In your case that risk involves a fire hazard. I wouldn't do it.

How many speakers can go into a single stereo system?
All amplifiers are rated to handle a certain speaker impedance. The majority of loudspeakers have an impedance of 8 ohms while most amplifiers will be able to drive a minimum load of 4 ohms. It is important to check the ratings of the amplifier before adding more speakers. If two 8 ohm speakers are wired in parallel, the total impedance will be 4 ohms. If 3 speakers are wired in parallel then the total impedance will reduce to around 2.5 ohms. If the total speaker impedance is lower than the rated impedance of the amplifier, it is quite possible to damage the amplifier as the output level is increased. To be safe, make sure you understand the impedances of the speakers and the amplifier's rating before hooking anything up.
What cable do you connect when installing a battery?
connect positive first then negative that is the safe way to do it
Is it safe to connect a 4 speakers to a 4 ohm amp?
First, you must know: There is no 4 ohm amplifier. All audio amplifiers have an output impedance of smaller than 0.5 ohms. So you use impedance bridging. No problem to connect the 0.5 ohm output to your 4 ohm loudspeaker. Scroll down to related links and look at "Impedance bridging - Wikipedia".
Is it safe to put the invisible shield's solution on the speaker at the back of the ipad 3?
You should not spray any solution into the speaker port of the iPad.
What kind of speaker wire should you use?
It is recommended to use oxygen-free copper speaker wire with a gauge appropriate for the length of the wire run and the power of the amplifier. Thicker wire (lower gauge number) is better for longer distances and higher power levels. Additionally, using wire with insulation that is rated for in-wall installation is ideal for a clean and safe setup.
