N00B Question

[BlownEARdRUMS 10+ year member]

I was told that if I get a 1000 watt Mono amp to play my 2 500 watt subs. They will not blow because amps and subs work like so: "think of it as gallons. each sub wants 500 gallons, so you will need 1000 gallons to fill them both up. "

Is that correct? I always thaught that the amp would still put out say 1000 even if you have say 2 1000 watt subs, I thaught that the amp would just have to work harder to put out the 1000

Thanks for puting up with my n00b ignorance //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

depends on the vc config of the drivers and the load the amp sees. say 1000rms@1ohm and you have 2 dvc 4ohm drivers rated for 500rms.

that'd be a perfect match (provided amp puts out rated power) and it'd be splitting the 1000watts between the 2 drivers (provided you aren't clipping the signal from the amp).

make sense?

I have 2, dual 2 ohm coil 18's...

Former explantion

"it says your subs are dual 2 ohm. for that, i would wire the voice coils of each speaker in series to bring the load up to 4 ohms. then you will have a pair of 4 ohm subs. once both are wired like that, connect the two speakers in parallel and you will have a total load of 2 ohms. then, find the amp you want that does 1000 watts at 2 ohms and you are done. (500 per speaker right?)

hope this was helpful. "

Why does it spilt and not just give the strait 1000. I guess I am thinking of amps wrong...

My thaughts were like an eletric motor. if it is at 100 rpm it draws 5 amps, add a load, it will try its best to get back to 100 rpm and draw 10 amps. I am applying that theory to amps. just replace rpm with watts. lol. w/e I sorta get it. amps will only put out its max per one load, if more loads are added the power output drops.

**** I feel like a n00b now LOL

There are 2 subs. Why would you think that a 1000 W amps would put out 1000 x 2 = 2000 W just because you increased the number of subs. According to that logic, if you added 20 18's, you could give them all 1000W off of the same amp.

oh and disregard max power. you'll rarely see it except maybe in 1 sec bursts or peaks.

yea its just like

HP sells cars, torque wins races

max sells amps, rms is what really counts

get a JL 1000/1

wire it to 4 ohms and still get a 1000wrms out.
