You are asking the wrong question. What you need to focus on when asking this question is amplifier efficiency rather than just the impedance of the load. If both amplifiers were the same efficiency into those respective impedance loads, there would be zero difference in current draw. What ibanender is likely eluding to is that most class D amplifiers will be more efficient at 4ohm than 1ohm, so the 4ohm impedance would likely result in less current draw. But the reason is because of the difference in efficiency, not impedance. It just so happens that efficiency is generally correlated with the impedance of the load the amplifier is driving. The same difference in current draw could occur between two different amplifiers of the same power driving the same load simply because of a difference in efficiency between the two amplifiers. So, moral of the story.....current draw is directly related to efficiency, not load. Efficiency is generally correlated with the load (lower the load, lower the efficiency). But efficiency of different designs and amplifiers will be different, so driving a higher impedance load does not guaranty a higher efficiency when comparing two different amplifiers. Thanks.... So moral of the story is I am looking to run 4 ohm still.... And depending on efficiency maybe I'll think about 1 ohm.

holy shyt!

welcome sir!!!

I assume you mean for your Icon? Do you have d2 coils? A lot easier and cheaper to find an amp putting out 1000wrms at 1 ohm instead of at 4 ohm. I know... wishful thinking.... Try to find a used Kronos. Hmm... You and I have discussed the Kronos before... It does has a SSF correct? looks like it is from 11-48hz ... That's good as I have moved to a ported enclosure... But the hook up for it looks insane.... I spoke with I think Chris from ZED audio and there is a specific way to hook up that amplifier to use it for a subwoofer... Basically I have to split my subwoofer output to all 4 inputs on the amplifier which he mentioned might "dirty" up the signal, to what extent I'm not sure... But hearing the word dirty and talking about output didn't sound good... I think because you're splitting the output connections the pre amp voltage then drops by a 1/2 to each input? And I'm not totally against running an amplifier at 1 ohm if it is stable to do so... Which any Sundown Audio I've been interested in is capable of... Just don't want to strain my stock electrical too much during this summer cuz I like turning the volume knob until it stops....

Assuming they were similar technologies, the 4 ohm would probably draw less current. However, in the mobile market, you aren't going to find a wide selection of 4 ohm class D, so you'd probably be comparing a Class A/B vs D which isn't a valid comparison. right, I'm not sure what you mean by saying there isn't a wide selection of 4 ohm class D amplifiers? If you mean that can output 1000w @ 4 ohm then you'd be correct, there isn't alot out there. But I was throwing a number out... I can easily find an amplifier that can output say 800w @ 4 ohm and one that outputs 800w @ 1 ohm. So the 4 ohm amplifier would draw less current from my electrical?

First question: Is your W6 sealed or ported?

Moral of the story.... Keep what you got unless it was like a M2a you were getting out of the deal....

Amazing man! Wish I could go to one of those events.... Looks insane!!

My curiousity is about actual Sundown ratings. Spec from your official site claim the rated output at 14.4v ... But all I keep reading are ratings higher than the specs and at 12-13v ... Reason I am asking is because I seem to hear alot of mix up about running amplifiers at 1 ohm and their current draw. I do understand the amps generates more heat and becomes somewhat "less" efficient at lower impedance.. Does it cause more strain on my vehicle's electrical though? Let's say for example I get 2 amplifiers, one is rated a 1000w @ 4 ohm load and the other is rated 1000w @ 1 ohm. Would one amplifier use more current than the other theoretically? Or is 1000w the same expense no matter the impedance?? I know some other conditions affect this answer but for argument sake, lets assume they are exactly the same except for output at different loads...

+1 ....

I will most likely pick up a SAZ-1500D when I get my monies in order and I'm not looking for a place to live....

Actually for his amplifier setup, the SA15 would be an almost perfect match up... A Dual 2ohm subwoofer will have a 4ohm or 1ohm load in the end depending on wiring. His amplifier is not rated to run at 1ohm which would mean he can't do it and if he could that would be too much power for that subwoofer. If he runs the subwoofer at 4ohms the SA15 would see about 750w of power... My vote stays... so ur saying get the dual 2 ohm sa 15 and run it at 4 ohms???? Yes I was saying that... This could work out even better as it has potential for a much higher output.... Potential being the key word here...

I need full power at 4 ohms!!! And by full power I mean at least 1000w at 4 ohm load...???

nice work!! looks like your getting the job done

That build does look insane already... Nice fit and look man... GL on upgrading though...!

For some reason I love all of the options on their autokits... Just don't know how to find out people's opinion on them since there is no "review" function on their site... It would be a great investment for them if madisound offered that.... Have you heard any of them personally 98???

awesome man!! if you were a Mormon I'd be one of your wives Lance!!!

I don't know if it's really necessarily better? but I'd like you to buy it and give us a review... Then sell it to me for 1/4 the price so I can has it! With a box and that subwoofer though you will most likely surpass that budget unless you go sealed...

welcome sir!!!

One wire is thicker than the other?
