how much you lookin to spend on the amp?

Here is a beast by Hifonics: http://www.woofersetc.com/index.cfm?fuseaction=product.display&Product_ID=4216

and another : http://www.woofersetc.com/index.cfm?fuseaction=product.display&Product_ID=4215

soundstream also makes a XXX amplifier : http://www.woofersetc.com/index.cfm?fuseaction=product.display&Product_ID=3174

and there's lots of 4000 watt amps, just have to look, woofersetc.com is a good one i think.

what vc is it

I assume you are also upgrading your charging system...? That's a big, inefficient sub that's gonna **** up alot of power, without a very stiff charging system you are wasting your money on such a setup.

Not dumping on your idea/system, just giving a heads up.

he said on ROE that it's going to be 16volts

I've played with the SS XXX15 many times. It's a bad *** sub to beat the crap out of. It's one of my favorite, so called "SQL", subs.

Out of all the Big amps...get the Hifonics Cyclops or the Goliath. Here's the reason why: The hifonics has the best protection circuitry. With that amount of currently draw...you will be clipping the crap out of your amplifier. Having the best protection will save your amp. I have never blown my Hifonics Cyclops. I even ran it at 0.125 on each amp. Even with a full clip...the amp went into protect. Many other amps will blow up very quickly.

Just maybe that's the reason why we bought a pallet of Cyclops for our shop. =)

thanks guys

i think the xxx15 is quad 4 coil

1.4ohm x4

i was thinking about a 1 ohm stable amp

what u think about the lanzar optidrive 4000d

i think its the same board as the soundstream xxx6500d

what box size should use

i willing to build a big box lookin to tune around 45hz

With that amount of currently draw...you will be clipping the crap out of your amplifier.

The fact that the amplifier will draw lots of current (we are talking about multi kilowatt amps here after all) should have no bearing on whether or not the amplfier's gain are set to allow it to clip or not. Id really like to know why you think the amplifier being large and therefore having a large current draw will mean the amp is more likely to be pushed into clipping.
I know you usually know your stuff Tuan, but this one has me scratching my head.

How many people do you actually know that has a large amplifier and turns the gain all the way down? Especially regular customers. When you throw in a 4" inefficient coil into the equation...many will tend to push their amps a little harder because of the expectation of the big amp big sub...and without the proper electrical system. I'd have to say that over 90% of car audio enthusiasts with big amps do not have the sufficient electrical system. Of course...you and I will never drive it to clipping...but many others will. Let's assume that it will clip one way or another wether for daily or competition...wouldn't you prefer to have an amp with a better protection circuitry? That's my point.

People also say going with an 'underpowered' amplifier results in the owner turning up the gains till it clips in most situations. Hence the notion that 'underpowering kills'. This is the first time Ive heard it argued the opposite way. But either way, we are on the same page, incorrect gain settings. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Maybe we should stop saying people tend to set gains incorrectly the majority of the time when X size amplifier is used, and just admit most people misadjust their gains no matter what sized amp they are running. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Yes...absolutely true. And because of the clips...etc...amp protection is crucial. Let me give you a great example...I have a customer with a Hifonics Maximus amplifier: stock alternator, 4 yellow tops...and cranking it all day long everywhere he goes. Still hasn't upgraded his electrical system after much advise.
