Can I use a subwoofer without amplifiers in a car?
You will always need an amplifier to run the transducer. The amount of amplification you may need will depend on what you pretend to do.Think of it this way. A loudspeaker power capacity is its capacity to handle power. Loudspeaker drivers are not self-sufficient and they have no power, they can handle power up to a certain limit.A 1000W woofer will work from 0W to 1000W, depending on its sensitivity. You should be able to have the loudspeaker “work” with 1W. So connecting it to your head unit directly would make it “work”. Would you be able to get good results? Probably not. Usually, the subwoofer needs twice the power you are feeding to the rest of the speakers in order to get “acceptable” results or be effective enough for you to notice it is there.Also, the woofer would need to be connected to a mono channel, if you connect it to either the left or the right channel of your head unit, you may not get all the information depending on how the recording/mixing was made, and you do not have an amplified sub out mono channel on the head unit. So, the result will be poor.But you have to consider that even your head unit has amplification inside (almost all do, some are only preamplifiers and will need external amplification for all speakers). Your car speakers would not work otherwise.So, without any amplifier at all, not even the one from the head unit, you can have the sub in the car, but it will be as useless as would be all the other speakers in the car without one. Unless you are an inventive person and manage to find a different use for your loudspeakerBut you have plenty of options on the market that “do not need” a separate amplifier. Just look for an active subwoofer, that is a subwoofer with an enclosed amplifier, one that does not need a separate one. You can find those in all sorts of shapes and with different specs. Just chose one that fits your needs.
If You Have A 1600 watts Amplifier Do You Have To Use The Whole 1600 Watts?
No, the whole amplifier doesn’t need to be feeding the speakers/woofers. It all depends on the impedance, the RMS power the amplifier drops out at, and the RMS power on the woofer. For example, here’s an amplifier. It does 1600 watts at a 1 ohm load and 1000 watts at a 4 ohm load. Your woofer is a single voice coil 4 ohm, 1000 watts RMS. You wired the woofers in parallel for a 4 ohm load at 1000 watts. 1 ohm, 1600 watts. 4 ohm, 1000 watts.
Can I use this amp with these subs?
Hi all, I have a Sony xplod amp, model xm-1502sx. specs. on it are: Amplifier Type Dual Channel RMS Power at 4 Ohms 0.04 W x 150 RMS Power at 2 Ohms 1 W x 150 I have 2 of these subs: profile baja bx10 4 Ohm Fs: 35 Qts: .57 Qms: 8.56 Qes: 0.62 Vas: 2.17 Xmas: .19 Re: 3.6 Le: .7 Mounting Depth: 4.5" Maximum Power Handling: 200W RMS Power Handling: 100W Cone Type: Polypropylene Magnet Size: 30 oz. Voice Coil: 2", 2-Layer Frequency Response: 20Hz - 1KHz Yes I know the amp and subs are not of the highest quality. How would I go about connecting them? Should I use one sub or both? Does it have to be bridged? Thanks
Can I use a 7.5 amp fuse in place of an 8 amp fuse?
Yeah, you can use the 7.5 amp, but it could blow easily. Higher amp fuses will always work, but if you use a higher amp fuse, you are defeating the purpose of using a fuse in the first place. Fuses are used to help protect your electrical system from damage by blowing if there is a power surge. If you use a fuse that is rated too high for your circuit, you run the risk of damaging your system.
Can you use an amplifier for a condenser microphone as substitution for phantom power supplies?
You would need an extremely rare (they are made, but not widely used) mixer or amp with a built-in phantom power supply switch, OR build your own (which isnt that hard), OR switch to a dynamic (non-phantom supplied) mic.A simple 48-52v supply across pins 1 and 2 is all thats needed. This can be inserted by a specially made cable, or an XLR M-F “passthrough” Neutrick’s makes a nice one. Easier still — why not just use a phantom power supply?
Can I plug an acoustic guitar into an electric guitar amplifier?
At the risk of sounding like a jerk here, some of the answers I've read to this question are nonsense.For the simple answer to your question: Yes you can & No it will not.An amplifier amplifies sound. It doesn't matter what guitar you plug into it… the amp doesn't care. An acoustic will not sound like an electric if you plug it into any amp. It will sound like an amplified acoustic.If an acoustic guitar comes equipped with a pickup, you can plug it into any amplifier. Will it sound different than being unplugged? Yes it will, especially depending on the kind of pickup the guitar uses.There are a few different types of pickups for acoustic guitar, they can be used individually or in combinations.A piezo pickup is placed under the bridge and amplifies the sound board, an internal microphone works off of the sound pressure inside the body, or you can have a system that utilizes both and allows you to mix the sounds together. There are also soundhole pickups like the Dean Markley or Seymour Duncan Woody, these work like a traditional magnetic pickup; you can also go the route of using a standard dynamic or condenser mic.On to the amplifiers.Whats the difference between an acoustic amplifier and an electric amplifier? I don't know!Marketing? Solid state… Tubes… hybrid; why do they make it so difficult?Money!Ok, some acoustic amps are pretty cool… they have reverb, chorus, “feedback eliminators”, single speaker, dual speakers, dual speakers with a horn. Single channel, double channel, triple channel, effects loops, line in, line out, direct out, balanced direct out… options is what I'm getting at.Most acoustic amplifiers are solid state which are excellent at producing clean tones; what goes in comes out louder with a high level of purity. There are tons of solid state guitar amplifiers out there that can do the same thing without all the bells and whistles.Guess what, a tube guitar amp like a fender deluxe reverb has a great clean sound… and tube amps have a different quality that I think sounds great with amplified acoustic guitar… and it doesn't make it sound like an electric! The key is setting the gain; if you have a separate preamp gain, keep it low and bring up the master volume to keep it clean.Experiment and have fun!
Can i use any wire as remote on amp?
you can use speaker wire as remote wire. preferably 14-18 gauge will work best for typical amps. only use one wire out of the 2
Why do we use op-amps?
We use Op Amps because having a tremendous amount of gain and differential inputs makes it -so- much simpler to design many types of circuits.The insane amounts of gain mean that the circuit can use massive amounts of negative feedback, making unparalleled linearity and bandwidth possible.Here is a good write-up by Analog Devices:http://www.analog.com/library/an...If you really want to learn about Op Amps, the best book IMHO is "Op Amps for Everyone". It has been through a few editions, the 2nd and 3rd editions are free online, the fourth is available in print and is well worth the price.2nd Edition PDFPage on ti.comPrint:Op Amps for Everyone, Fourth Edition: Bruce Carter: 9780123914958: Amazon.com: Books
