I know it sounds dumb to all you stereo gurus but I was just wondering what it meant and what's a good number to get? Thanks!

an ohm is an electrical resistance. it depends how many you want for what you are doing. give me some more info and I'll try to answer your question better.

Well, I have been looking at some new speakers lately and I have seen varied numbers for the ohm. All I want is a pretty decent sounding system. I have one 12" sub and I wanted to find some decent 6x9's to go with it. I want the sub to hit but not as loud as everyone elses cars. And I need some good 6x9's so the sub doesn't drown out the actual music. Any suggestions? Thanks. Oh, these are the specs of the sub

Single woofer
IMPP composit cone
Long throw excursion
Dual layer surround
Long voice coil design
MAX. Music power: 400W
Nominal Power: 100W
Speaker size: 12" (30cm)
Impedance: 4
Sensitivity: 92dB/W (1m)
Frequency response 20-4,000Hz
Gross weight: 4,51kg 9LB 15oz

ok most 6x9s are going to be 4ohms unless you do some funky stuff with the wiring. I won't get into it unless you want me to. also by looking at the specs I'm guessing you have a pioneer sub? also what kind of amp are you using? how much power? for 6x9s I would recomend something with a higher SPL rating. I spent $100 for a pair of kenwood 6x9s and they sound pretty decent. its up to you how much do you want to spend also? also did you want to know what an ohm was because of you sub or just a general question? hope I helped!

you only really need to pay attention to ohms when you are looking at amps and subs. 98% of speakers are 4 ohm and any others will be clearly marked or mentioned. most subs are either 2 or 4 ohms per voice coil. the point of dual voice coil subs is to vary installation setups. i myself have a dual 4-ohm voice coil sub. that means its got 2 4-ohm voice coils. this allows me to run the amp at 2-ohms when its bridged parallel and 8-ohms when its bridged in series. this becomes more useful when using multiple subs.

i got a little description of ohms in my site here ... http://home.earthlink.net/~deadtrend...mplifiers.html
thats basic right there, you can search "what is a ohm" or something like that from www.ask.com, and get a big session about it.
