Sold FS:Memphis 4kw *NEW*

[MEMPHISFLEX 10+ year member]

Dont know how this will work out since Ive made alot of enemys on here and so forth, but ill try it! Ill ship first, and everything. So anyways I have one of my Memphis 4kws left, this one was in my buddies demo build for his shop, hes a memphis dealer, used very very little maybe 20min of play time at most, did a couple shows with it thats it. Had it hooked to two Memphis 08 mojos at 1ohm, never dropped below 13.5volts. The amp was clalmped at one of the comps at 4460wrms @1ohm at 13.8volts, and these are .5ohm stable. Still have all orginal boxes, manuals, plastics, will have the full memphis 2 year warranty also! Gunna ask $660shipped, which is cheap for a pretty much brand spanken new one, I have seen used ones go for that much!! Trades welcome!

edit:Ill get pics up as soon as I can, the wind is making my sat. internet really slow, and cant upload on photobucket.

Ummm these test were done out of the durango in lafayette at RP's shop. And the other high voltage test were done on the new SS van they are building. It is basic math... amperage times voltage equals wattage.... And who says the test you READ are accurate either come on man... you are taking way too much offense to this. And memphis is mainstream. And I did the exact same test on my kole 2400d and it is doing 1400watts rms at 1.3 ohm with imp rise. you telling me that amp is over a 1600 watt rms amp? same method same results.. If you argue the results you argue that the kole 2400d does more than 1500 to 1600 rms

Ok you are right about the durango... it Did only like 1980 or some sh*ty watts.. However it was like 3.8ohm rise and at 10v drop.. We resently tested the 4kws in our ss van at 1ohm on 16v batterys with a 1.8ohm rise doing 4430 watts and 5200 at .5 ohm with the same rise

Ok i just clamped the 4kws in my avalanche they were doing 3278 at 1 ohm with a 1.9 ohm rise off 16v batterys *car off* @38hz

batterys resting at 16.9v dropped to 16.2v

Something everyone needs to know is just because your amp says 1500 watts doesnt mean it will do it in real world app even if it is a true rms rated amp.

Second Thing is Memphis 4kws are Bad A$$ amps how ever like every amp they have atleast one down side. 4kw being they are current hogs and run hot.

Big plus side being under right power and app they produce a butt load of power.

System for those that dont know:

2 Memphis Mojo 15's

2 Memphis 4kws

6 16v Powermaster Bat

Daily Tuned

152.2db termlab sealed on the dash @38hz

Man I can't say for every test you have done... but the one I did for you guys in the durango was approx 2400 watts and imp rise was around .8 ohms. it was I believe 50 something amps and 40 something volts. Now again if you did independent testing that is fine. Just going off when I was there. And the test for 5kw when I was there I believe was imp rise around 1.2 but any testing you did after that I wasn't there for sorry if inaccurate. ONLY going by what I saw. Not downing anything you guys do I like soundcheck a lot. But I have some guy attacking me here that obviously doesn't understand the total science behind things and got pissed off

and I never stated the amp was bad by any means. it is a GREAT amp for the price. figure the kicker 2500.1 is what 1200 ish shop cost (not sure off top of head but for sure more than 4kw) and that thing is a great amp but doesn't do 4kw

any amp on this power level needs a beefy *** electrical to even keep it above 12v. measuring at 10v and 3.8ohm rise you're obviously going to get some shitty readings. no one should buy this amp or any amp like this without the proper electrical backing and expect power that isn't there.

for a few months i carefully ran my 4kw off a 220amp alt, 2 runs of 1/0, and only a g34 yellowtop up front. i would never let it get under 12v and ran it 12v all day long, rarely would get warm. but i can see how 16v and .5ohm would makem get hot. but out of 5 memphis amps ive ever ran the hell out of, i've never had one that wasnt near bulletproof to thermal limits. great amp imo

it was .8 at 10 something volts

On music I am in the 13's for the most part. But when I play a 49hz tone (Tuning) i drop to around 12.5 after a second or 2. Amp gets a little warm. i have never felt it hot. But then again i aint feeding it the current it deserves.

whoops. misread ftl.

and memphis is definitly mainstream compared to the things we deal with in here.

And exactly!. this is what I was trying to say in reference to the planet audio's earlier. After imp rise and voltage drop most amps are lucky to see half of rated RMS

Yeah that is a 4 door from the bed you are hitting those numbers from that impressive... I just upped the power on mine. wired that amp 1/2 ohm daily and taking it... pulling like 175 amps getting a tad warm lol. We are metering it this weekend if everything goes right on brocks new meter

 

[vehementSPL 10+ year member]

Well that sux cause I was about to use the Memphis 4k on my 2 Critical Mass UL12 (can handle 2500 RMS each). I figured that since they're 1.5 ohm VC's that the Memphis would put out around 3k (since they're rated at 4k @ 1 ohm, and 2k @ 2 ohm). So what do you guys think it would put out at 1.5 ohms? Or should I wire it at .375 ohms and hope that it's closer to 1 ohm with rise? Or is that too dangerous?

I would put it at 1.5. Remember most subs are rated at a wired RMS.... or at least from what I have seen... But that is up to you.... But besides that I would be afraid of smoking the amp. ... but what do I know... ::shrugs::
