Just got a set of 240gt's and will be getting a IDMAX12D4 aswell and am stuck on what amps to buy?

I like the look of the alpines but think that the power will not be enough as I was think of the MRV-T420 for the dyns and a MRD-M501 for the IDMAX (or do people think these will have enough power) so I was wondering what other amps at around the same price people could reconmend, but please not audison as I find them a little to plain to look at as I know the 2.500 + 1.400 are the best ones to get.


Any help would be good, and also may end up putting in a set of rear speakers so maybe a powerfull 4 channel would be good.

Thanks

There's a guy from OZ on ebay selling u-dimension amps at good prices.

How much exactly is your budget?

[shiny_car]

it depends on how you personally define loud. and i guess that's too hard without having the dyn's and IDMAX installed!

in very general terms, most speakers/subs go very loudly with 30~50% of their rated power being delivered. it's as much as you'd probably use for normal operation.

it's always 'nice' to power-match your components, but realistically (unless you compete in SPL or poorly efficient speakers) you may be overcapitalising.

as such, the alpine V12 combo you suggest is probably plenty of power for your needs. tune it correctly to get full power from them (with volume setting up full and no clipping) and you should have a very usable system. of course there's the option for the more powerful V12 monobloc, or consider bridging a 4-channel for the dyn's (or bridging 2x 2-channel amps).

alternative amps would include the PG Ti Elite / xenon, boston accoustic, tru technology, dls, precision power, xtant, JL audio, soundstream, etc. all these brands offer high SQ amps that may suit your needs.

my shortlist would include (aside from alpine V12 and audison LRx):
*tru tech
*boston GT-24/28
*JL audio 300/4 + 1000/1
*PG xenon 200.2 + 600.1

but for no good reason other than availability, reputation and model choices; yet they would offer the SQ you'd want i suspect. sorry, not sure on pricing (i have a habit of deciding first, finding out price later :wink: )

[PROS15]

if u r after powerfull sq amps then i think u should have a good look at the new range of rockford fosgate punch series of amplifiers, they r really powerfull and now incorporate a lot of tghe features only seen on the power sreies in the past, add to this superior cooling technology which gaurantees long life and these r great value
something u might look at would b the p5002
this is powerfull enough to run as 2channell for splits
or bridged for sub 500wrms
and all of these amp r highly under rated, ive witnessed this model amplifier with a birth certificate rating of well over 600wrms, and all the rockford amps comply with the new CEA amplifier standards rating, so this is gauranteed power

[BlackRain]

Those new rockford amps need some serious cabling (or at least thats what the website says).
And they don't have the smallest foot print around. Their 2003 predecessors were a much more user friendly size IMO. Those amps had tiny footprints for the amount of power they were giving out.

Personally I think the new range is too high maintenance and you can probably go something a bit more 'convenient'.

I'd be lookin at the stuff that shiny mentioned. All high quality stuff there to match the rest of you gear.

And throw Zapco into that list too..they're excellent amps. Big difference from the old V12 amps I used to run, and retail prices were virtually the same.

[biteme]

O.k have been doing some looking and have come up with two amps that I am very keen on and want to know if the will give me enough power for the gear I have and that I will be getting.

PG Ti 400.2 for Dyns
PG Ti 600.2 for IDMAX12D2 now not dual 4 and I dont think this amp will run a 2 ohm


These will be coming from the states as they are much cheaper and yes I know about the warranty issues.

What ya all think of these?????????????????????????

the Ti amps are excellent. note that if they are 'titanium' series then they have become superceded models; whereas the 'titanium elite' is the current top range series. not sure if there's any major difference though: evolution rather than revolution.

i'd seriously recommend a monobloc for the IDMAX ahead of a bridged 2-channel. it'll offer a slight edge in grunt. choose the impedence IDMAX to match, whether that be D2 or D4 depends on the amp and it's associated power output.

i would use something morepowerful than the alpine MRV-T420 amp unless you use two and bridge them

dyns love power and 2 X 110watts rms @ 14.4 really will not do

look at something at least 2 x200watts rms or more!!!

[E320Titanium]

I think the PG Titanium Elite amp will be out of the question due to its cost at around US$10,000. :shock:

AND YES IT IS 2500 watts PER CHANNEL x 4. :hehe:

But if you like the PG Titanium amps (some one else on here does too :wink: )
then have a look at the Ti500.4 75x4 or 250watts x 2 bridged for your front stage and a Ti800.1 mono block for your sub.

[Brian Mc]

Check out the-
ARC Audio 400.4 & ARC Audio 900.1
Rockford Fosgate P4004 & P3001
Boston GT40 & GT22
Your Alpine are a good choice as well.

Zapco 350 for Dyn's 2x100wrms 4ohms
Zapco 500M for IDMAX 1x 360wrms 4ohms, 1x 500wrms 2ohms

or

TRU Tech C-7.2 2x250wrms 4ohms for Dyn's & 1x1500wrms 2ohms for IDMAX

or

Boston GT24 2x175wrms 4ohms for Dyn's
Boston GT24 1x900wrms 2ohms for IDMAX or Boston GT28 1x1250wrms for IDMAX

or

PG Xenon 200.2 2x200wrms 1-4ohms for Dyn's
PG Xenon 1200.1 1x1200wrms 1-4ohms for IDMAX

all comes down to your budget and /or if you want to stretch it...

[heimerich]

With that price range, why don't you consider Audison LRx???

utter nonsense
i had the PG zx 600ti feeding dynaudio sys240 Esotars so about 160wrms per side and they went plenty loud
as shiny said, you'll rarely even use 50% of the power you have on tap and will be overcapitalising. all these ppl saying theyve fed so and so amounts of power into their amps.. its all wank factor IMO
that alpine amp will be fine in terms of power and there are heaps of other alternatives as the others mentioned.
keep in mind the old rule that for a 3db increase in sound pressure level you need to double the amount of power being fed to the speakers so realli between 110wrms to 140,150 or 160 there wont realli be a difference apart from added headroom.

Caliber Zetus Z-4800, 360rms x 2 bridged for the dyn's. or Ca475+ 2 X 240rms for the dyns.
a Caliber CA2000D+ for the sub.

see http://www.eaudio.co.nz/z4800.htm for the zetus.
http://www.eaudio.co.nz/ca475plus.htm for the CA475+

"i had the PG zx 600ti feeding dynaudio sys240 Esotars so about 160wrms per side and they went plenty loud"

did you ever try the spits with a more powerful amp?

ive used many amps and i can say the more powerful i went the better my system sounded. I dont care a bout a loud system i just want an effortless sound that is clean. More power gives you this. So far my old ppi is still the best thing ive used on splits rated @ 2 x300watts rms beat my bridged xtant 404m 2 x 200watts rms. My adcom i preferred in bidged mode running 2 x300watts rms. With the dyns i had i just preferred more power.

i know of one person a few years ago using bridged alpine 1505s to run their dyns, this person had also found that the dyns improved with power.

the best thing about my new speakers is that they dont need this kind of power 85watts rms is enough :-) , however im now choosing 150watts rms per channel.
