high power small footprint amps

[adio 5,000+ posts]

Can anybody recommend a sub amp that DOES RATED 1900 - 2500 watts @1 ohm with a very small footprint??? I have a crescendo s1500.1 now but im just wondering....

the crescendo BC2000D appears small. largest dimension is 16". Also the Synergy Audio WFO 15.1D is pretty small too, just at about 17". Lot's of people giving feedback that they're getting close to rated on them. And the Orion XTR2500.1D. 2500x1 @ 1 ohm and 12.6v. Longest measurement on that amp is 14".

Stetsom 4k

Wired to 1 ohm, youll clamp around 2k to 2.5k with 12.8 volts

Only way to get 2k out of a korean 2k is wiring half ohm or lower at 14.4 to 15 volts.

PRV Audio AD4000.1 2Ohm Amplifier 4100w RMS High Efficiency Car Amplifier AD4000 | eBay

Ive been trying to look into these amps, maybe picking one up and to see how well they may operate.I really havent looked up any real testing results yet though.May be an amp to be considered??

Anyoneeeeee use a prv amp yet, I was reading/researching various threads about people who tested Brazilian amps and most of the problems start to occur at 1 ohms testing, on amps rated at 1ohms. The 4000.1 prv seems like a good buy at $399. Anyone with feedback besides "if you have good electrical"...no disrespect but has already been confirmed by the majority.

Yep. This is because it's not proper to wire speakers in a fashion that would exhibit a reactive load around 1ohm. So the internals are not built to sustain that output.

That's why it's common to say if it's rated at 1ohm, expect their 2ohm output rating from it.

Some Taramp's amps that we have had a hand in releasing as well as a few others over the last 2 years have been upgraded to handle more "abuse" since people no longer know how to install audio anymore..

The amplifiers that are 14.4v rated can handle 0.5ohm wiring with explicit recommendations to prevent potential failure.

With these new amps, there are 2 ways to get maximum output, wiring low or running high voltage. Luckily, the safer and cleaner method is to ditch wiring low and run over 15v and wire no lower than 1ohm. You will retain over 90% efficiency levels while keeping the amplifier happy and loud.

So for example can I wire at a one ohm load since my two woofers are dual 4ohm and just keep my gains down. The two

Ohm output would be more than plenty.

 

[shizzzon 10+ year member]

Yes. I do not understand why need to keep gains down.. Sounds like you are looking at amplifier too large.

However, if you are like me, i typically use MUCH headroom so to allow my equipment to never clip even at the speakers thermal limit.

Clean is always best.

 

[BCotrell 10+ year member]

That is the plan, to have the headroom.

You get what you pay for. Nothing cheap is good and nothing good is cheap.

I plan on picking up one of these amps after the new year and run it for a bit to see how they perform/work. I may take some pics and run a thread to let people know about my experiencing of the brand and model chosen. I know its a few months out, but I am also needing to get some installation done to accept one of these to run
