ok i just heard sum1 sayin these are not good amps? i thought they were good amps giving 2000wrms at 1ohm, was i wrong??

They are good amps, but need a decent power supply. Some people have had problems caused by low power to the amps IIRC.

Also Im not to sure but Pro Plus customer service isn't supposed to be up to much but I can't really comment having not ordered from there.

Hope that is a little help even tho its a little sketchy, others might be able to help more.:)

As volvoman says, supposedly they make the power they say they do, but due to the way the amp's pwoer supply is designed, when the voltage drops (due to massive current draw) the amp draws more current to compensate, and it fries it's pwoer supply stage IIRC. So split charge is a must when using this amp. But apart from that problem and the lack of a subsonic filter, people are generally impressed (for what the cost).

dont get.. get something better built. IMO.

they are all fine and dandy if ur boot is full of batterys and u just burp at spl comps but in the real world, driving in the street, it sucks. much too much unreliable for my liking.

I have just Brought one, Wont be installed untill march.

I have been Recomended to Get a good alt some thing like a 120amp alt or 180/200amp alt, and 2 Yellow tops in the boot. :)

As people said they are ment to be good for the money. Cheap power. I only want it for Daily Driving.

I had one for a year,and never had the slightest problem with it. :p

i had one for a few months and it went ar4e over tit on me, thats with yellow top and 15v reg.
ask bassmechanic about its reliability problems as well.. he was saying one of the toridial transformers just fell off.

well dodgy imo.
as with all things regarding hifi. you get what you pay for.

I can vouch for the power issues with them. I used to have 1 when they first came out and blew it within a day. The place I got it from changed it and the new one died within a week. I was using 2 yellow tops at the time with split charge but only a 60amp alternator and 2 gauge cable.

When they go they go in a big way. One of them set fire and nearly took the sub with it. The second one just made a weird sizzling noise and cut out. Shortly after that Pro Plus actually took the 1ohm power figure off their website but its back on now. I dont know if they've improved it or what.

I would say get something more stable or prepare to fit some serious battery/alternator power.

nope its not mate, that ones currently off for repair :)

my other blew because the split charge relay blew, so no charge from alt, means it was effectively running engine off and voltage fell and fell, output transistors blew...

keep the engine running if your spanking it, run a batt or two in the boot, and nice thick power wire and there fine!!!

enjoy :D :clown:

Yeh 2 Yellow Tops hopefully 180amp alt split charge and 0AWG all round :)

i'm gettin one but only runnin it at 4 ohm i got 4 gauge wiring but no second battery got a cap on it will i get any probs ?

sooo.... basically nemesis 250? nice cheap for the power.....but 2 yellow tops 300. mega alt couple of hundred?!?

soooooo........end up costing the same as a quality amp that dont need the mega power supply as a necesity...hmm :lol: ;)

on the site it tells you the specs of the ammount of current required to run them

4 ohm = 35 amps
2 ohm = 90 amps
1 ohm = 190 amps

hope these specs mean i'll be ok runnin it in my car at 4 ohm with uprated wiring but no special alternator or battery

Its not until you start dropping the impedance that you get problems. My mate had one at the same time as me running a couple of 12's at 2ohm and had no problems. In fact its still running now nearly 2 years on.

Its almost as though the Nemesis wants to be 1 ohm stable but can't. Like Jordan wants to have a nice face but can't.

Onnie
28-01-2004, 05:24 PM
mine went nuts running 2ohm..
never run it at 1ohm, except after it developed its problems just to see out of curiosity..

like snowie said, bigger alt, more batts, what else?? might as well just get a DECENT one in the first place.

IMO :)

I'd agree with that.Theres better out there for not much more cash and you wont need as much other hardware to back it up. Avoid if you can unless you want grief.

In my opinion if you buy an amp that claims to be 2000 watts RMS at 1ohm then you kind of feel annoyed when it doesn't do exactly what it says on the tin without a majorly uprated electrical system.

Snowie
28-01-2004, 06:03 PM
yep :cheese:

cant wait to get my us amp....hmmm 1000w on the box @ 11v...... and theyre underrated and dont over heat.... thats an amp!

ah but a Gennsis ( how ever u spell it ) monoblock 1200wrms at 1ohm pulls 170amps!!!! thats only 20less than the Nem, and the new puts out 800wrms more.!

28-01-2004, 07:56 PM
Oh yea i found These Numax Batts that are £70 each and have 110amps so 3 of them wud be just under £200 and be betetr than 2 Deta Orbital Deep Cycle ( like yellow tops ) :D

28-01-2004, 07:58 PM
but how good is the genesis's circuitry? and is it a class d? - no! :p :p

I was'nt saying in the Slightest fact that the nem will be better, i am just saying u still need a good power surply for the genesis's ;)

I'll probably be getting Numax batts to run my Nemesis, they are great value for money.

By the way is the £70 you quoted including postage because i've seen the 110AH Numax for sale at about £45-55 not including postage?

Keviño
28-01-2004, 08:27 PM
a good power supply is a must for any car audio imho...

but i dont think a genesis monoblock will really require 3 batts and 2 alts :p

and imo u goin a bit overkill on the nem, but, hey, thats not a bad thing :)

On this Webby there > HERE (http://www.adverc.co.uk/products/batt/numax.asp)

There NUMAX - Leisure/Marine (Deep Cycle) L110 110 346 x 172 x 239 , £56.01.

All prices ex-VAT

It says, so i am guess about £70 each, i dont know about including postage not sure.


kw_maher [Mr T lover lol] True but dont for get i will have a Directed 4500, i am guessing thats got atlest 60amps?

Bear in mind that the Numax Leisure batteries are designed to supply a small amount of current for a long period of time, and thus aren't really suited to a car audio environment...

Very true, I do aggree. I'm sure they will be capable of producing high currents though. They are deep cycle and therefore have thick plates, so should be able to cope with higher current draw. I'm sure I read on a Numax leaflet that they can be used to run a starter motor.

I don't think they will do the job as well as a yellow top or deta but for the price I think there worth a try.

You can get several Numax's for the price of a yellow top and all those AH's and CCA's have got to add up to something.

Besides Reactsystems has been using Numax's for a while and I haven't heard him complain about them.

I guess I won't know till I try though. Just my 2p. :)

28-01-2004, 09:04 PM
Sorry Blade u know i am a Complate Radish.

Ok what i am saying is Reactsystems is using them. And they Say Deep Cycle so why cant we use them?

Blade
28-01-2004, 09:05 PM
Your welcome to go ahead and use them, but I wouldn't expect them to perform as well as other batteries, as the design is not optimised for discharging large amounts of current over a shorter space of time... Black-Cat looked into this before, i'm sure he could shed some light on the subject

hotdogs_r_us
28-01-2004, 09:09 PM
Ok thanks blade.

I mean i know nothing, But if we were to use 2/3 Batts would it then Proform better?

bassmechanic
28-01-2004, 09:24 PM
me and andrew were talking about batteries last night, from what hes saying (and hes used em for a while now!) they seem to cope well enough ;)

They are also not sealed like the Optima.

Optimas can be placed anywhere at any angle.

These will have to be placed facing up and also on a battery tray which won't corrode if battery acid leaks and also will not let the battery acid flow anywhere.

Cheers, I'd forgotten about that. Won't make a difference to me though, I'll be building them into MDF boxes to keep them secure. I just need to work out a way of getting some ventilation to them. :)

You'll need to treat the MDF to make them safe :)

If the battery does leak, it will run down the battery and melt the MDF.

Spraying the MDF with Hammerite will solve the problem. Normal spray paint might do the job, not sure.

dude, theres absolutely loads of stuff on the forums referring to this.. use the seach function! :rolleyes:

maybe this is what you want?

http://www.rthursby.co.uk/acatalog/deep_cycle.html

the £55 one is the numax... the small price may outweigh the downsides.. but for a better deep cycle thats sealed, you cant really get much cheaper than that!
