Would 13cm speakers fit ok?
hi, im buying some new speakers for my vauxhall zafira elegance and im not sure about the sizing. would i be able to put any size speaker in or would i have to find some that are the fitting size. iv found some speakers for the front and back, the front speakers are 16.5cm which is the standard size for the car and iv also found some rear speakers but they are 13cm...but the size for the back speakers is 13.5cm. do you think the .5 really matters do you think they would fit or not. The Product Spec For The Front Speakers : 16.5cm/6.5'' Blue Injection-Molded Polymica Cone Woofer Specially Treated Rubber Edge Suspension 40 oz. Magnet Structure 0.75'' High Temperature Aluminum Voice Coil 28mm PEI Dome Tweeter 260 Watts Max Power Sensitivity: 90 dB Frequency Response: 55Hz-20KHz Impedance: 4 Ohms Mounting Depth: 1.15'' the rear speakers are the same but smaller in size (13cm)
What is the difference between 4 ohm and 8 ohm car speakers?
Two things... Most amplifiers give only 2db higher sound volume at 4 ohm compared with 8 ohm and a perfect amplifier (which normally are incredible expensive) give just 3db higher... And 3db is actually the minimum sound volume difference you easy can hear with music, when you adjust the volume!And most SIMPLE amplifiers / car stereos demand 4 ohm or higher... And even when an amplifier work with 4 ohm instead of 8 ohm speakers, are they then like a car engine that run almost too fast and some get over heated, so they shut down temporarily or simply melt down... Remember also that a 4 ohm speaker often goes down to 2-3 ohms when they play music... And when you use 4 speakers, will normally 8 ohm become 4 ohm for the amplifier and most amplifiers demand minimum 8 ohm speakers IF you connect four speakers, which normally is written on the back... So you better buy 6 to 8 ohm speakers!And if you want to play loud, remember that you can easy find fine speakers that are 6 to 10db more sensitive, than ordinary 88db/w/m speakers and plus 10db sound actually twice as loud!
Can 2 ohm speakers be used on a 4 ohm stereo system?
Yes, but...Let's say you have a 100W amplifier designed to drive a 4 ohm load. This means that the amplifier is designed to provide[math]V = sqrt(P * R) = sqrt(100 * 4) = 20V[/math]and[math]I = sqrt(P / R) = sqrt(100/4) = 5A[/math]If we don't want to overload the amplifier then we won't want to exceed these limits. So a 2 ohm load can be given a maximum of[math]P = I^2 * R = 5 * 5 * 2 = 50W[/math]without driving the amplifier out of its designed specifications. This maximum current will occur when the volume knob isn't at maximum, so it will be quite easy to wind the wick up too far.So the amplifier won't be able to deliver the "nameplate" power into the load. Most amplifiers are voltage rail limited. If we assume that the amplifier has 20V rails (per above) then the amplifier could, in theory, attempt to deliver[math]P = V^2 / R = 20 * 20 / 2 = 200W[/math]Depending on the amplifier, this could simply result in distortion until an output protection circuit engages, or it could blow up the output stage, or it could blow up the speakers.
Can you use 8 ohm speakers on a 4 ohm stereo system?
Can you use 8 ohm speakers on a 4 ohm stereo system?Yes. The Ohms rating stated on an amplifier is generally the minimum, not maximum.Note that if the power rating of an amplifier is rated at x Watts at 4 Ohms, the maximum output at 8 Ohms can be as little x/2 or one half the rated output at 4 Ohms. IOW, as Ohms go up, maximum SPL (sound pressure level or volume) goes down.This also delineates the problem of an amplifier driving a lower Ohm load: as the Ohms go down, the amplifier tries to deliver MORE power, likely more power than it’s circuitry is rated to handle.Remember that Ohms is a rating of impedance - the AC equivalent of resitance (also remember that audio is essential an AC or alternating current).As Ohms drop, you get closer and closer to a short circuit. As most of us know, putting a short across the source of power (i.e.: a power amplifier). This is going to cause that source to overheat and/or burn if the circuit is not interrupted by a fuse, thermal breaker or other protection device.I know this is more than you asked for. I hope, however, that it gives a broader picture of that the Ohms measurement means.Good luck.
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.
Is there a fuse for the speakers in a saturn l100? if so would this cause the speakers to not work?
take the speaker that is easiest to get to and hook it up to the house Stereo to test it. and if it works and worked fine before u put in the aftermarket Stereo in then u have to bypass the factory amp usually under the seat or in the trunk look at the owners manual and go to install shop for bypass wire harness kit maby 20-30 dollars tell them they will understand i had a 1995 Mazda b2300 truck had the same problem. and if you want to check out the wiring in the truck or car take the Stereo out and disconnect the wire to 1 speaker from harness and put Speaker to it if it works and the door wire does not the wire is shot from opening and shutting the door or moisture hope this helped
Where to put tweeters in a 1995 s10?
I've always liked A-Pillar mounted tweeters. You A-Pillar is the bars on the side of your front windshield... I've got gauges on my driver side A-Pillar, and i would think that a tweeter would fit just fine in the same enclosure i bought for my gauges. Just buy the right diameter. I bought mine from the local parts house, but look up JCwhitney and Summit for your model A-Pillar gauge pods and see if they fit for your application. They may also make pods SPECIFICALLY for the tweeter.
Why do my front door speakers not always work in my car?
I have had my stereo system in my car for quiet a while. The door speakers are stock, the head unit is not, and I added 2 10 inch subs with a 1000 watt sony explode amp. The whole setup has worked. Recently though my front door speakers stopped working. They are off most of the time but sometimes they'll randomly come on (going around turns, stopping, sometimes just cruising) and they'll stay on at that point until I shut the car off (most of the time). It leads me to believe that its wiring but I've checked all of them as far as the head unit goes. I even put the stock unit in and it didn't do anything.
Is it necessary to have midrange speakers in a car?
in most three way designs the mid range is built in and yes if you want clarity in certain notes it is necessary to have mid range
