Stupid amp ?

[SamG97Camaro]

Ok I know nothing about car audio and this question will prove it, so sorry guys. I have always wanted to know about powering subs. If I buy 2 10's with and rms of 400W will i need an amp that is 400x2 or 200x2...I know i can go less in W and I plan on it but i meant for the sole purpose of the most it can handle. I just wanna learn how all this stuff works, thanks for all the help, maybe someday I'll understand it.

can the 2 10's each handle 400w???....400w rms??...or just 400watts....you need to look at the specs of the speakers soundomain.com is good .....my audiobahn 12's say 500w on the back of them, come to read they can handle a steady 6-700w rms power with a peak of 1000w a piece....you should look into a mono amp which is specifically meant to power subwoofers....I myself have a 2 channel 1000w amp but thats just because it was cheaper you also need to look into what impedance (ohm) you will be running at, some amps say they have 1000w but thats only if running at 1ohm, some subs may not work smoothly with a 1ohm load and could possibly fry the voice coils.....goto sounddomain.com and read some of their article, or goto our stereo/electronics section and read everything....you will learn alot ;)

lesson in electronics:

Speakers and amps are rated in two different power terms: peak power and rms(continous)power. Peak power is about twice the amount of rms power. If a speaker or amp says it operates at 400watts rms, that means 400W continous with a peak of about 800W. The peak hits when the bass hits hard. Amps and speakers also have an impedence value. Inpedence is resistence to electric in ohms. If you have a 400Wrms@2ohm amp and you have 2 10inch speakers @2ohms per speaker you will only get that full 400W if you wire the speakers to have a total impedence of 2 ohms, which is not possible with 2 2ohm speakers. you can either hook the speakers up in series or parrell. in series you add the impedence of each speaker and in parrell you divide the impedence by the number of speakers. If you hook your speakers up in series, you will get a 4ohm load, which will cut the power of the amp by half;200W. if in parrell, you will get 1ohm, which doubles power. Some amps are not stable at 1 ohm though. Find out the exact specs on your speakers and amp and do the math to get the most power out of your system.
