ok, so i have an old speaker box, but at least 3 of the speakers are blown, and i don't know how big the speakers are that i need to buy, do i need to measure the hole they go in, or the cone itself, or what? also, i don't have ANYWHERE NEAR the power i need to blast these speakers at full power (2 boxes an 800W cone, 2 tweeters, and 2 midrange, plus my 4 100W speakers for teh surround) and i need to know if, even though i don't have that much power, will i still get the great loud sound i want (like it's simply a maximum), or do i need that much power just to get any good sound?

Please don't answer if you have no idea, only answer if you acctually know what you are talking about, or have some sort of instructional site for me to go to or sumtin. thanx alot.

ok, guys, by the way, it's a home speaker set, i know what impendance is, the speakers are all running 8 ohms, as is suggested from my receiver, which only pushes 400W

If we are talking about decent speakers, you shouldn't just replace a speaker with the same size speaker. Speaker cabinets are built to match the specifications of speakers, sound quality will suffer if they don't match.

Write down all the information written on the magnet & buy the proper speaker to replace the speaker, if it needs replaced. If it doesn't need to be replaced, rebuild it, or have someone rebuild it.

Maximum wattage, or peak wattage is meaningless. RMS wattage @ 20Hz -20KHz is the only useful wattage information for speakers & amplifiers. All other wattage ratings is just marketing hype that serves no purpose for the consumer.

It's a lot better to have have too big of an amplifier, than too small of an amplifier... unless you actually like constantly blowing speakers. An under powered amplifier will blow your speakers a lot faster than an over powered amplifier.

I know this sounds so wrong, but the proper size amplifier for a speaker is one that is rated 1.5 to 2 times higher than the speaker is. So if you have a pair of speakers rated at 100 watts RMS, you need an amplifier rated at least 150 watts RMS @ 20Hz - 20KHz per channel.

Oh boy, where to begin-
The power rating on a speaker is typically a maximum load- a 100W speaker can handle 100W load- but you also need to understand impedance. The impedance of a home theatre speaker is typically 4, 6, or 8 Ohm (8 being the most common). A wattage rating NEEDS to be accompanied by an impedance rating because they are directly related. Likewise the power rating on your amplifier should also give 4 and 8 Ohm ratings at the very least.
If your are running multiple speakers from a single amp channel, it makes a big difference how you connect them as well. A SERIES connection (where the signal flows thru one speaker, then the other) of two 8 Ohm speakers gives you 16 Ohms; a PARALLEL connection (where both speakers are connected simultaneously to the amp) drops your impedance to 4 Ohms. As a general rule you do NOT want to drop your impedance any lower than 4 Ohms.
Generally speaking, running an amplifier into a HIGHER impedance load will not harm anything; running an amplifier into a LOWER impedance load can damage the amp.
Amplifier power is often misunderstood- if you have a 100W amp and you double the power to 200W, you've only increased your max volume by 3dB, barely a noticeable difference to the human ear. Amplifier power has more to do with signal processing and clarity than it does volume. At normal listening levels, your amplifier is only pushing a couple of watts per channel; the power is used when there are sudden changes like a movie sound effects explosion.
Unless you're running an outdoor PA system or a concert hall system, 100W per channel should be more than enough to handle your music or movie system. If you need to go higher than that, you'll probably be deaf in a couple of years.
As far as speaker size is concerned, you should measure the diameter of the driver cone itself. Typical speaker sizes are 4, 6, 61/2, 8, 10, 12, and sometimes 15in drivers, though I'm sure there are some anomolies.

Is this for your car or home? Because to power them, you'll need a car AMP for your car, and for your home, you'll want a an AMP attached to a CD player or your computer.

Anyway, you will need an AMP to connect the speakers via speaker wire. As for speaker size, you can measure with a ruler from the cutout in the box. the sizes go in increments of 2. Tweeters are usually 2" to 4". The mains, are can range from 6" to 20" and above. Subwoofers come in all sizes, bigger than the sattelites and mains and mids.

The 5.25 speaker is especially used for the mid variety frequency and the ten inch is especially for the bass. length and watts does no longer matter. First you need to make your techniques up what you're utilising the speaker for. From the skill score of the audio gadget, it sound like a vehicle audio speaker. you won't be in a position of combination vehicle audio and homestead audio. vehicle audio is designed for a small section and homestead audio for greater desirable room. you do no longer see many homestead audio audio gadget that have that variety of skill score in any respect. undergo in techniques that the bass is the main annoying frequency interior the audio. you besides mght ought to have a skill amplifier that would grant the sound sparkling alongside with the audio gadget. by skill of staying with call style call you will get sparkling sound. Demo the audio gadget first along with your individual source of fabric. wish this could help you out.
