# 2 ohms: 500 watts x 2 chan.
# Bridged, 4 ohms: 1000 watts x 1 chan.

im just wondering coz 2ohms 500watts for 2 chan. is equivalent of 1000, right?
or the use of 4 ohms with single chan.???

Are they both into one sub or are you planning 2 subs with 500 watts vs. 1 sub with 1000 watts? If it's just one sub...it's the same, if it's 2 subs, then the two will be louder all else being equal.

Depends on the box.

thank you for the reply denonite and fresh1 at least i have a little idea

what does the box have to do with anything? OP, yes 500x2 at 2 ohms stereo is the same power as 1000x1 at 4 ohms mono, both are 1000 watts. Whatcha gonna use that amp on? If you're gonna use that amp for a subwoofer or subwoofers run the amp at 1000x1 at 4 ohms and get a subwoofer thats either single 4 ohm voice coil or dual 2 ohm voice coils or two subwoofers that are dual 4 ohm voice coils each or dual 1 ohm voice coils each. hope this helps

Absolutely nothing I guess. I have seen with my own two eyes 1 sub on less power get louder than 2 subs on more or equal power, but I guess I was dreaming. It could also depend on the number of speakers, which was never brought up, nor was the purpose of the amplifier/setup.

Theoretically, 2 12''s would be louder than 1 12'' on the same power, because there is more surface area with two subs than one, which means more air is being moved, and as we all know sound is basically moving air. Thanks for not answering the original question or adding anything useful besides impedance options, but I have a better one. Check this out:

To the OP, what you're gonna wanna do is get four 250 watt rms 4 ohm single voicecoil subs and wire them in pairs, wiring in parallel down to 2 ohms, then wire the pairs in series up to 4 ohms, giving you 1000 watts.

thanks again fresh and T money..... i have a 2 channel amp with 1000watts (?) and 2 10s jbl gt 1014D so i decided to make a parallel to make it 2 ohms and use both channels..... what do you think?

i guess reading> you. If you read i told the OP that both 500x2 and 1000x1 are both 1000 watts, so wouldn't that tell anyone that they are equal in loudness. OP never mentioned what he was gonna run the amp with so i gave him options on which way to wire it if he's using a subwoofer. Whats your point, i have seen 1 sub get louder than 4 subs of equal size all running on the same power. Obviously if he did mention subwoofers than we could ask him what enclosure he would be using on the amp and then explain which set up would be louder.

Anyways, OP if you have two jbl 1014d subs, they are single 4 ohm voice coils so if you wire them parallel you'll get 2 ohms and the amp you listed is stable at 4 ohms mono. That amp will not work to its full potential with the subs you have. You should either get a mono(1 channel) amp that is around 700 rms at 2 ohms or wire your subwoofers in series and run the amp at 8 ohms. You won't get much power but atleast you won't blow the amp. What amp are you referring to by the way?

Uhhhh, did I miss the title of the thread? That's why it depends on the box, which means my original statement was correct, as it has now been made clear that it is for subwoofers. Thanks for playing.

P.S. "i told the OP that both 500x2 and 1000x1 are both 1000 watts, so wouldn't that tell anyone that they are equal in loudness" You can tell the difference in loudness between 2 speakers getting 500 watts each and 1000 watts to 1 speaker? That's awesome. Probably impossible, but awesome.

Hug?

OP please list the amp, but it sounds like your best be would be to change the amp like t money said, or change the subs to better match the amp. If you change amps, I think there is a Kenwood in the for sale section that would be an excellent choice.

You're so smart lol. "Uhhhh, did I miss the title of the thread? That's why it depends on the box, which means my original statement was correct, as it has now been made clear that it is for subwoofers. Thanks for playing". So since you assumed he's using the amp for subwoofers, i guess its fine for you to assume he wouldn't be using the same box for the subwoofers lol. He's asking about amp power not amp and subwoofer set up. duhhh. Thanks for coming out lol. "You can tell the difference in loudness between 2 speakers getting 500 watts each and 1000 watts to 1 speaker? That's awesome. Probably impossible, but awesome" Wish i could understand your english, have no idea what your point is.

Sorry for the hijack OP, some people get butthurt when you ask them a question
