TRUE or FALSE?

Im shopping for an amp that will deliver 1000watts rms to 2 subs.(1k per sub) A friend of mine told me I could by an amp that has 1k rms x 1 @2ohms and if I wired the subs right I could get the full 1k to each sub instead of the power being shared and split in half. Is he an idiot or am I inexperienced?

False

False and don't buy any Pyle crap or anything similar that says 2000 watts and expect to get it either.....

Since you even bothered to post the question the answer to the question I have boldfaced would be ~ Both.

But there's nothing wrong with inexperience. We were all there once upon a time. Now you've come to ask a question about something you didn't know - now you'll know and consequently you won't be as inexperienced any longer. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Inarguably your friend is an idiot, though. Kick him in the nutz for us and tell him to quit spreading misinformation that is not only incorrect but flatly stupid.

An amp is designed to output X amount of wattage at Y level of electrical resistance.

Let's use your example of an amp rated to output 1,000w X 1 @ 2 Ohms.

That amp, when presented with 2 Ohm worth of resistance, outputs 1kW.

Whether you use a single Dual 4 Ohm subwoofer or 100 different subs to achieve that 2 Ohm load the amp's output at that resistance will remain static.

A single DVC 4 Ohm sub with the coils wired in parallel to make a 2 Ohm load will get the full 1kW by itself.

If you were theoretically able to combine 100 different subs to create that 2 Ohm load and the resistance on each individual driver were the same then each one would receive 10 watts of the amp's 1kW output.

Now I guess there is some truth to your idiot friends statement.. A lot of amps that put out X power at 2ohms do put out two times X power at 1 ohm... That being said... This is not always true and is definently not a rule of thumb to follow...

Any recomendations? I was looking at the power acoustik a300db which says it does 2300rms @ 1ohm but Ive heard they arent always honest. $400 max shipped.

out of curiousity what subs are you trying to power?

2 15'' Type R's or 2 15'' Solobarics(L7) still undecided.

I always thought that was weird, I mean it is a resistive load and P=(V^2)/R so theoretically halving the resistance should always double the power, but I am betting that efficiencies and other things get in the way of that.
